The production of the thermal energy technologies in cogeneration, successfully implemented in Brasov

General Electric and Bepco held Friday in Brasov, an event that aims to meet a social need which is increasingly more stringent  in Romania’s cities: the construction and operation of an efficient central heating. The event, held under the auspices of the American Chamber of Commerce in Romania and Brasov City Hall, presented solutions based on thermal energy production technology in high efficiency cogeneration. A solution of this kind has been successfully implemented with CET Braşov. Basically, the four high efficiency cogeneration plants operated by Bepco in Brasov are equipped with 11 Jenbacher gas engines manufactured by GE Distributed Power. The four plants generate 42 megawatts (MW) of electricity and 38 MW heat for the city. “Our cogeneration projects have solved one of the main problems related to energy efficiency of  heating system in the city of Brasov.

“Given the financial problems  the former company responsible for the production and supply of heat to the city faced, we had the opportunity to implement the GE solution based on gas engines, which offer greater efficiency systems to our customers and it contributes to Romania’s objectives in terms of energy efficiency, “said Simina Costan, Managing Partner at  Bepco.  The General Electric gas engines offer increased capacity of cogeneration  to Bepco plants, with an overall efficiency of over 84 percent and an extremely high ratio of  electric genergy/ heat energy.”

“Given the advanced age and the low energy efficiency of most of the urban heating systems in Romania, our gas engines for high efficiency cogeneration offer a major potential for operators across the country who want to upgrade their heating systems. We are pleased that, through this project for urban heating, we can help achieving the energy efficiency goals of the Bepco plants, “explained Karl Wetzlmayer, the General Manager of the piston engines division  for GE Power & Water Distributed Power. For this project, the  Bepco plant CET Nord 1 was equipped with 5 units GE 4-MW J624, and CET Nord 2 with  3 gas engines  in 2 stages GE Jenbacher J624 of  4.4 MW (the J624 engine is the first gas engine model in two-stages  in the world).  The CET Metrom  has two J620 engines and the New Station CET CHP  is equipped with a new J616 engine.

The modernization of the heating systems

The cogeneration Bepco plants,  equipped with 11 Jenbacher  engines type 6, produced by GE, are part of the campaign carried out by Romania for modernization of the urban  and industrial heating systems which are outdated and less efficient, in order  to reduce emission levels resulted in the process of  generating energy. Basically, by implementing the GE cogeneration technology in the place of the separate facilities for electricity and thermal energy,  operators achieve direct savings of energy of approximately 40%,  due to the reduction of the  fossil fuel consumption. The integrated fuel control system of emissions produced by GE helps respecting the strict global requirements and generates a reduced carbon mark.

 

For example, a cogeneration plant of a 1 MW capacity and equipped with a  GE piston engine can eliminate  annually the equivalent  of CO2 emissions generated by 800 European cars. In addition, given the location of cogeneration system being much closer to the end user, the losses during transport are reduced or eliminated entirely. GE Jenbacher, the  gas engine division of GE, constantly develops new projects to improve the performance and efficiency level of the gas engines, by using the latest technologies. Launched in 2010, the two-stages engine, J624,  is one of the strongest and most effective created by GE and  represents a new standard in the gas engines  technology for GE and for the entire industry.
