Annotation: Data of the decentralized manufacture state of thermal and power energy on Ukraine territories, have been given as well as criterion of a drive choice for the electric generator which can be used both an internal combustion engine, and gas-turbine plant are cited in the clause. Schemes cogeneration installations are considered on the basis of an internal combustion engine and two utilizes, on the basis of an internal combustion engine and a water-heating boiler, on the basis of an internal combustion engine and condensation block, on the basis of an internal combustion engine both the steam turbine of low power and the combined scheme with a steam and water-heating boiler. It is proved that while choosing the type of the equipment it is necessary to define the efficiency of various scheme of installation solutions as a whole on the basis of the analysis of their thermal balances. An addition to that power efficiency – operating ratio index is defined of fuel heat, as mellas the basic units in which there are the greatest losses of energy. As a result of the carried out analysis it is established that the most effective of the considered schemes is the cogeneration installations one on the basis of an internal combustion engine and the water-heating boiler.
Keywords: system of heat supply, cogeneration installation, an internal combustion engine, thermal balance, operating ratio of fuel.
