Study of the efficiency of cogeneration plant based on an internal combustion heat engine (ICE)

Колієнко, А.Г.

The results of thermal and environmental tests of a cogeneration plant (CP) based on a gas-piston internal combustion engine with a total nominal thermal capacity of 2.46 MW are presented, of which 1.26 MW is nominal thermal capacity and 1.2 MW is electrical. Russian aggression against Ukraine led to significant losses of both basic and shunting generating capacities of thermal power plants and to a decrease in the production of electrical energy in nuclear and hydroelectric power plants. In this regard, work on the introduction of distributed sources of electric energy, including CPs based on internal combustion heat engines as gained considerable importance. Given the sufficiently long economic life of such devices, their implementation should be carried out on the basis of acceptable energy efficiency. The article deals with the issue of developing a methodology for surveying the energy efficiency of CPs, determining the technical and economic indicators of their work, researching the factors influencing the energy efficiency indicators of CPs and ways to increase of their efficiency. The work is based on the results of regulatory and corrective works performed by the authors at CPs, analysis and generalization of the results of CPs surveys.
