The best 10 place to organize Energy Conference in Turkey

Dear Colleagues,

Every year we either organize or just participate to conferences in Turkey on various instances. It is for sure that these conferences help us to communicate with our business colleagues, to learn more about ongoing business activities, to update latest information, to increase our network capabilities, to meet with our potential clients or partners to make further business.

It is a real business potential and there are many private companies in Turkey who are organizing energy conferences. Unfortunately they organize these events mostly in Istanbul. However these conferences in Istanbul have no use for real business. Istanbul is an international city, that is for sure. But for energy business, Istanbul has no meaning for the business opportunities, nor any result for future.

Istanbul is a good place to see historical sites. It is good for other business meetings. It is good for you to take your wife there on company expense account. However in case of energy business, you will return to your home office with almost no result.

Energy business capital city in Turkey is Ankara, capital of Turkey.

All decision makers in public enterprises are situated in Ankara. The Ministry, State water works, Public Electricity companies, Coal Board, Energy regulatory Agency, they all have head office in Ankara. Istanbul is another country for them.

All key local and international companies have offices in Ankara. They should be available to meet with the key public decisionmakers at all times when needed. Living in Istanbul or elsewhere and coming to Ankara for one-day business flight will have no meaning.

When you participate to an Energy Conference in Istanbul in one of fancy hotels in the city center, or in conference/ fair centers on the outskirts of the metropolis, you will have no communication with your counterparts in the public sector. For sure that the key people will come to that event, all expenses paid by the organizers in legal format, you will have the opportunity to listen to their same speeches already presented maybe 100 times earlier. They will be giving the same speech and after they will immediately disappear in order to meet some other business or private colleagues.

The most important energy organizations take place in Ankara. Ankara is the center of all core decisions.

The most important speeches are always given by the Minister himself. You should follow him in all his presentations. He will be giving the latest information on ongoing energy business. All other public figures will be repeating his declaration.

Participation to an Energy event in Istanbul is waste of time and money. Do avoid any event in Istanbul. It is no use for you and for your business expectations.

Remember to join to any event which will take place in Ankara in the main auditorium of the Energy Ministry. That is the most important place for all energy meetings. The key energy figures will be there available for you at all times, by all means. They will have ample time eager to share with you. It is very cost effective.

Also please do remember that you should be available in Ankara one day earlier. We see people coming from other cities by the early flight, arriving to the conference venue at about noon time, and try to leave as early as possible to reach their evening flight as soon as possible. We watch them with pity.

Here are our best 10 place to organize Energy conferences in Turkey. They are all in Ankara, capital city of Turkey.

Ministry of Energy and Natural Resources Auditorium Ankara
National Library in Ankara
Conference Center (KKM) in ODTU Campus in Ankara
Bilkent Hotel in Bilkent University Ankara
Gazi Engineering Auditorium Ankara
Sura Salonu Gazi University Ankara
TOBB University Auditorium Ankara
MTA Auditorium Ankara
ODTU Alumni Conference Hall in Visnelik Ankara
Tubitak Conference Hall in Ankara

We would wish to put Hilton, Sheraton, Swiss hotels into our main Top10 list, but unfortunately, these luxury hotels are difficult to reach at the city center. Key figures, and their staff normally try to avoid to participate to these events since city traffic makes everything so miserable. Car parking is so difficult if not impossible most of the cases. Anyhow it is good to know that we have also other alternatives available in Ankara

Above given list is tentative and it could be revised with your assistance in time. However any new entry of my preference will certainly be in Ankara.

In one of new energy conferences in near future, on 4th May 2007 afternoon, we shall have an important Gas Conference in Ankara Sheraton Conference Center and your moderator will be an humble speaker to try to explain the professional market responses of the Chamber of Mechanical engineers, evaluating the ongoing activities in the gas market, as well as new opportunities in future in his capacity.

Please do join me in that important event. Details are in our web site. You can also ask me the details through my email address. Your comments are always welcome.

CAYIRHAN FGD

A New Step in Clean Energy Production
2x150 MW- Cayirhan Thermal Power Station-
Flue Gas Desulphurization System- 1987-1992

Dear Colleagues

In order to learn the technical and commercial details of “Flue Gas Desulphurisation” we had a very good opportunity to work together with a reputable International Company in installing a system in a local thermal power plant. There is nothing difficult, nothing so secret.

To meet our country's increasing energy demands, the Turkish Electricity Authority's power plants fire poor quality lignite of low calorific value, high ash and high moisture content, which can not be utilized elsewhere. This operation introduces environmental hazards which have to be avoided. Under the current strict environmental regulations, the Authority considers this their major problem to solve, - avoiding environmental pollution while producing electricity from economic fuel sources. Due to the high sulphur content of the fuel from in its mine, Cayirhan Power Plant was selected for the installation of first Flue Gas Desulphurization (FGD for short) System in year 1987.

Since this installation was an integral part of utility plant, and was the first of its kind in Turkey to apply desulphurization techniques to flue gases, Cayirhan FGD system was regarded by the Authority as a major step in the application of these measures for the control of Environmental Pollution.

The successful initiation of this FGD plant emphasizes the validity of this solution of a technological process applied for a cleaner environment. Even the additional costs of such a solution still allow for economical energy production.

Starting at this point, the Authority decided to make long-term commitment to install similar FGD systems in all other utility power plants.

General Information on the Project

The FGD facility, integrated with the 2x150MW capacity Cayirhan Power plant is 120km from Ankara city center, and is located in Nallihan county, near to Cayirhan town. The Cayirhan Power Plant supplies 1,800,000,000 KW-hr of electric power into the national grid each year while utilizing poor-quality lignites from local mines.

The proximate analysis of the lignite which is based to Cayirhan Power Station is as follows,

Average Lignite Proximate Analysis,

Lower heating Value, 2,800 kcal/kg
Ash 41.3 percent (dry basis)
Moisture 27.5 percent
Total Sulphur 4.65 percent
Combustible Sulphur 4.15 percent

Since the combustible sulphur is quite high at 4.15 percent, under full load of the two units of the power plant, 30 tons of SO2 is calculated to be discharged to the local environment each hour. This is the prime reason for building the FGD plant.

The contract for FGD plant was signed on 3rd July 1987. It is on a turn-key basis, with a consortium formed by Bischoff- Kloecner- Lentjes of Germany and the local partner in Turkey. The contractual lumpsum price was 71,638,715 DM, plus 4,387,482,000 TL. By having the credit agreements to cover the project effective as of January 1988, the subject installation has been in operation since November 1991 in parallel with the utility plant.

The financing of the FGD plant was 100% from foreign sources, which also included coverage for the local portion.

In Cayirhan FGD plant, conventional cleaning with limestone solution is applied and gypsum is obtained as the byproduct. The plant comprises 2 each 100% operation lines. Flue gases from each utility unit are cleaned in separate cleaning lines.

The Cayirhan FGD plant is split into 3 major sections, which are the limestone preparation unit, the cleaning tower, and the gypsum water extraction unit.

Flue gases passing through the existing Electrostatic filters and newly modified flues are sent to the cleaning tower by booster fans. The cleaning tower is where the SO2 is removed. For each boiler unit, there is one cleaning tower. While the flue gas raises through the tower, it reacts with downcoming pulverized limestone solution. The SO2 in fluegas is thus absorbed by the solution, forming gypsum.

The limestone solution that is passed to the cleaning tower is prepared in the "Limestone Solution Preparation Unit". The raw material for this unit is obtained from the limestone mine only 7 kms (4 miles) from the power plant. It is transported as precrushed particules with maximum size of 6cm (2.5 inches). There is one additional 100% spare unit for the crushing at the location where the limestone solution is prepared and transferred to the cleaning tower.

The flue gas, from which 95% of the SO2 content has been removed, is then discharged to the atmosphere via the "Wet Stack" situated at the top of the cleaning tower.

The gypsum by-product which is removed from the bottom of the cleaning tower is dried and filtered in hydrocyclones and vacuum filters. This dewatered gypsum is then sold on the market as a saleable industrial product.

Our experience was an extraordinary opportunity to teach us the details of an FGD systems. It is our feeling that now in Turkey with local young intellectual and engineering capability, we can repeat the same project in other thermal power plants without or very limited foreign assistance. All we need is self-confidence and confidence of investor who would put money into similar other projects.

“Believe in yourself, first. Then believe in the Lord, Paramatma. When you have faith in these two, neither the good nor the bad will affect you.” By Sathya Sai Baba

Once again we would like to congratulate the Purchasing Authority and the creditors who put money which made the project realized, and to the engineers/employees who make the plant to run smoothly, efficiently at maximum availability. Your comments are always welcome.

Save The Planet

Dear Colleagues

We are in the business of designing, making, and installing steam boilers for industrial and electric utility applications. Therefore we feel that we are obliged to respond to the announcement for ”Save the Planet” by specifying the common issues from a professional point of view.
Our steam boilers derive their heat requirements from the combustion of fossil fuels - gas, oil, coal, etc. There are a number of environmental concerns connected with this process that we would like to address.

The Combustion Process

When a pure hydrocarbon burns there are two products of this combustion. Water (H2O) is produced from the combustion (oxidation) of the hydrogen components. Carbon dioxide (CO2) is produced from the combustion of the carbon components. These two products are inescapable results of burning hydrocarbons. This oxidation releases heat, which is used in industrial processes, as well as in the home.

Carbon Dioxide

There is a continuing discussion on the effects of the increase of the carbon dioxide levels in the earth's atmosphere. It is one factor blamed for the so called "greenhouse" effect, which predicts a warming of the earth's atmosphere.

Carbon dioxide is a vital component of the earth's atmosphere. From it the trees, and all green plants, derive the carbon they need to build leaves, roots, branches, and trunks. In this process they take in carbon dioxide, absorb the carbon, and release oxygen. In the burning of fossil fuels we are releasing the carbon stored up by the plants thousands or millions of years ago.

Fossil-fuelled boilers for electric utilities and industry are one contributor to the carbon dioxide in the atmosphere. Another major factor in the increase of carbon dioxide levels is the destruction of the world's great forests. This is doubly damaging. Not only are the trees - that take the carbon dioxide from the air and return oxygen to it - being destroyed, but the process by which so much of them are being destroyed - by burning - is adding significant levels of carbon dioxide to the atmosphere.

Automobiles, and other transportation users of petrochemical fuels, are also a significant factor in contributing carbon dioxide to the atmosphere.

It should be the policy of all boiler industry to design and supply boilers having the highest possible efficiency in the conversion of fuel to useful heat. In this way the addition of carbon dioxide to the atmosphere is reduced to the lowest possible level for a given amount of heat produced. There are designs of boiler that are less efficient in this process, and they are less expensive to produce. We should not supply such boilers.

Other Combustion Products

As well as the two major products of fossil fuel combustion, there is a range of other products of combustion that are released into the atmosphere. What these are depends mainly on the fuel used.

When coal or oil have sulphur as one of their constituents, then the products of their combustion will include oxides of sulphur. Unless removed from the flue gases before release into the atmosphere, these sulphur oxides can combine with moisture in the atmosphere to produce sulphuric acid and other undesirable sulphur compounds. Equipment is available to remove these oxides of sulphur from the flue gases. Companies supply such equipment at the request of the customer, where the sulphur level of the fuel calls for it.

Another undesirable group of potential combustion products are the oxides of nitrogen (NOx). If released into the atmosphere these may combine with moisture to form nitric and nitrous acids, thus contributing to "acid rain". Designs of oil and gas burners are available which minimize the formation of these oxides, and these burners are supplied only when specified by the customer.

Fluidized Bed Combustor, Atmospheric/ Circular

In the specific case of coal, there is a combustion process known as the fluidized bed combustor, in which the fuel is mixed with limestone (calcium carbonate) and then burned. During the combustion process the sulphur combines with the calcium carbonate to form sulphates, which are then removed with the ash rather than being released to the atmosphere. Many companies are in the development of fluidized bed combustors, either in “Atmospheric bubbling” or “Circular”. This technology is available in many companies, who are managing a research programme to adapt this process to the specific lignite fuels. Another advantage of this technology is that the combustion temperatures in the fluidized bed combustor are such that negligible amounts of the oxides of nitrogen are produced.

Integrated Gasification combined cycle/ IGCC

IGCC firing technology may be employed. Here in this technology you build a sort of refinery next to the future power plant to generate "Synthetic gas" from poor lignite then you fire this synthetic gas which comprises mainly H2 and CO, in the combined cycle power plants similar to natural firing. We need to make extensive research if it method is applicable for our lignite

Municipal and Other Wastes

Another environmental concern is with the growing volume of solid waste material from our cities and industries. With a greater sensitivity for our environment, and an increasing scarcity of land, the practice of dumping such wastes in landfills is becoming less acceptable. Techniques exist for the combustion of such waste material in an efficient and environmentally viable manner. This process not only minimizes the landfill problem, but also produces heat which may be used in district heating schemes or for the production of electricity. Municipalities are to solve their solid waste disposal problems through industry, who are ready to work with forward thinking municipalities in its application.

Nuclear Power

One major source of electric utility power generation produces no carbon dioxide release into the atmosphere. This source derives its heat from the controlled disintegration of nuclear fuel in a nuclear reactor. This heat is then transferred to water to produce steam to drive turbines. Although there are waste products of the nuclear reaction that require considerable care in their handling, storage, and disposal, many logically thinking people agree that nuclear power offers the best solution for long term thermal power production, with the minimum effect on our environment. In the 4th generation plants there is maximized security and minimized waste. Local engineering capability is to be employed at the highest level in order to absorb the technology for best use in national advantage.

Safety

The combustion processes used in these boilers involve high volumetric heat release rates and intense flames. Careful design and meticulous attention to detail are required to operate this equipment safely. Accurate and continuous measurement, monitoring and control are essential to operate within the design parameters. Utilities should use only the most up to date, microprocessor controls and instrumentation for these tasks. There are suppliers for the equipment which will operate on a continuous basis completely automatically, with a minimum of operator monitoring, thus ensuring maximum efficiency and safety in its operation.

All steam generating boilers contain steam at high pressure. The integrity of the pressure bearing components is of vital importance to the safety of operating personnel. All boilers should be designed, built, and tested in accordance with the stringent requirements of the Boiler and Pressure Vessel Codes of European Union as well as the American Society of Mechanical Engineers.

We have lignite coal as our biggest fuel source and we all agree that we should use that coal

with maximum efficiency and availability,
with minimum harm to the mother nature,
with minimum impact on global warming.

The world has a lot of coal, but right now carbon capture and sequestration is not commercially viable, and no guarantee it will be in the future.

Solar and wind plants have long term availability problem.

Natural gas has national security implications and does emit CO2 which creates global warming.

The primary energy sources for new capacity and energy efficiency measures need to be chosen using some kind of quantitative risk-assessment scheme that most likely will result in a diverse energy mix that includes nuclear.

We are really not sure how to get around/adapt to the global climate change problem without some drastic changes, even if nuclear energy is implemented.

Finally

Although every action we take, every time we move or speak, has some effect on the environment, it is the major effects that must be addressed if we are to act as responsible citizens of a all-too-fragile world.

We should design and supply which does have an appreciable effect on the environment around us. It should be our policy and our concern that any impact on the environment be minimized as best we know how.

We should continue to apply the best technical solutions to these concerns, with maximized local engineering capability and make best use of our local fuel resources.

We will not compromise our designs with inefficient solutions when we know a better way.

We should work with our customers and the community to provide the cleanest, safest, most up to date technology in the equipment that we supply.

We are citizens of this world and intend to act responsibly in it.

The Best 10 Renewable Power Plants in Turkey

Dear Colleagues,

In Energy Commission of Chamber of Mechanical engineers in Ankara Branch, we meet every two weeks on Monday evening in our Ankara office in order to review current energy issues, and try to make appropriate programs/ panels/ technical excursions.

Earlier we had following conversation at the end of our regular agenda. In our country we are just pointing the negative issues. We need to point out the positive developments. We should be more proactive.

There are good developments. There are good power plants/organizations, running smoothly, generating power with high efficiency, at high availability rates. We need to review them and appreciate their performance and advise them to be good examples to continue.

In our draft 2007 technical excursion program, we decided to list them and invite our colleagues as well as students to visit these selected sites, review the operations, write down reports. So we make that list and visited those 10 best thermal power plants one after another

Now we are planning to visit our selection of "The best 10 renewable Power Plants in Turkey". The close location to Ankara is our first criteria in our selection to enable us to organize daily technical tours to selected sites. Here is our list for the best 10 successful renewable power plants we planned to visit later this year,

We would like to visit our selection of the best 10 RENEWABLE power plants of Turkey later this year and further plan to write technical articles to explain these excellent thermal power plants in our month bulletin.

The primary energy sources for new capacity and energy efficiency measures need to be chosen using some kind of quantitative risk-assessment scheme that most likely will result in a diverse energy mix that includes nuclear.

Your comments are always welcome.

Ayen Energy CCPP in Ostim Ankara

Dear Colleagues,

That was on 3rd March 2007 Saturday morning, we had our coach at 0930 hours, we departed from the sidewalks of the chamber of mechanical engineering office with 40 participants,

10 undergraduate Mechanical Engineering undergraduate/ graduate students, 15 young/ 15 senior mechanical engineers, we left the city center, to the Ayen Energy 50 MWe combined cycle thermal power plant for a technical excursion in Ostim, almost 20 km’s west of Ankara.

On the coach, we introduced ourselves as the member of Energy commission of the Chamber of Mechanical Engineers in Ankara

We explained the thermal power plant which we would be visiting, advised the participants how important/ efficient/ new, the power plant is,

Ayen Energy CCPP project is in Ankara Ostim Organised Industrial Zone. Major investor is Ayen Energy in Aydiner Construction Group.

Ayen Energy Co. is founded in 1990 within the framework of the provisions of the "Law no. 3096 regarding the Appointment of Organisations other than the Turkish Electricity Authority for Electricity Generation, Transmission, Distribution and Trading." 15.01% of the corporate capital stock is open to the general public.

The first project accomplished by Ayen Energy on B.O.T model is Kisik Hydro Electric Power Plant (Kisik HEPP) with an installed power of 86 MW at Tekir Town in the city of Kahramanmaras. Secondly, Ayen Energy realized Camlica-1 HydroElectric Power Plant (Camlica-1 HEPP) with an installed power of 84 MW with the same model. The company is to operate both plants for 15 years. Third , Ayen Energy realized Yamula Hydro Electric Power Plant (Yamula HEPP) with an installed power of 100 MW.

The new CCPP project is at OSTIM Ankara organised Industrial zone firing natural gas in CCPP to generate 40,967Mwe electricity. General Contractor is Gama Power Systems (GPS) of Ankara.

GE Energy is the supplier of gas Turbine. GE Aero Energy, a GE Power Systems business, has received a contract from GPS of Ankara, Turkey to provide one LM2500+ with Dry Low Emissions (DLE) gas turbine-generator set.

The 31,077-megawatt LM2500+ HSPT gas turbine-generator set is used by Ayen Ostim Enerji as part of the Ayen Ostim 40,967 MW Combined Cycle Project in Ankara, Turkey.

The combined cycle power plant also utilises a 9,89 MW steam turbine generator supplied by GE Thermodyne of France. The plant supplies a reliable power source to the Ostim Organized Industrial Zone and potentially excess power to the public grid.

The LM2500+ gas turbine-generator set is packaged at the GE Aero Energy packaging facility in Houston, Texas, and delivered to the Ayen Ostim Combined Cycle Project in late August 2003. The unit started simple-cycle operation in late March 2004, and combined-cycle operation in May 2004. Natural gas is served as the primary fuel.

Aalborg is the supplier of HRSG. In January 2003 Aalborg Engineering signed the contract with GPS who is the general contractor of the plant, to supply the HRSG for the end user Ayen Ostim Enerji's new 40,967 MW natural gas fired combined cycle power plant in Ankara, Turkey. The contract covers design, procurement, production, erection supervision and commissioning supervision of a complete dual-pressure HRSG plant.

All equipment is purchased in various countries by Aalborg Engineering and the erection work is carried out by GES company on behalf of GPS. HRSG is Aalborg standart package type "SteamGen8" at 30 tph MCR HP at 55bar/482C, and 7 tph MCR LP at 5bar/ 265C.

GES Electric Construction company is the general contractor for site installation of all equipment plus cabling, switchyard etc.

Electricity sales agreement is completed with Ostim administration. Natural gas purchase agreement is with BOTAS

Inlet air cooling equipment is also purchased. This equipment increases the electricity output of gas turbine by 3-4 Mwe in hot summer period.

There are 154KV high voltage overhead lines passing above the plant, they have no connection with the plant since plant generates electricity at 34.5kV to feed Ostim.

Overall plant layout and necessary basic engineering were delivered by Foster Wheeler Bimas of Istanbul.

Ostim Administration and the Ostim entrepreneurs will receive electricity at some substantial figures lower than the current TEDAS prices. This is a great saving for the nearby enterprises, to reduce their electricity cost during their own fabrication facilities.

This is the first CCPP project for Ayen Energy. Ayen has three hydro plants in operation. With this experience in thermal power plants, it is expected that Ayen would be having similar success stories in future.

We wish to congratulate Ayen Energy management and the Aydiner Group for their new OSTIM CCPP project completion, and hoping all the best in future for more and bigger projects. We then completed our plant excursion. We had tea and cookies, thanked our hosts. We congratulated them for having and running such an State-of-Art Combined cycle power plant with high efficiency, and high availability.

We were happy since our colleagues had visited a very good/ efficient, state-of-the art, latest technology combined power plant in Ankara

It was a real good job. Congratulations to the investors who put money to make the project realized, and to the employees who make the plant to run smoothly, efficiently at maximum availability

Your comments are always welcome.
