Description
This municipal enterprise, operating J920, totally refused the old less effective boilers. The heat produced by this engine is used for the hot water supplying and heating, the electrical power is transferred to electric power system networks. The electrical efficiency of J920 can be up to 48,7%, which makes it to be the incomparable leader as for the fuel utilization factor at electrical power production and is the most important economical and environmental indicator of the engine. The utilization of the cogeneration equipment with the total efficiency more than 90% confirms the highest effectiveness of J920 in its class.
