FIELD: power industry.;SUBSTANCE: invention relates to power industry, in particular to heat and power supply of residential buildings, household and industrial premises. The advantage of this invention is the repeated use of thermal and electrical energy, which reduces fuel consumption and at the same time allows one to receive more of both electrical and thermal energy. When burning fuel in an internal combustion engine, in addition to generating heat for heating rooms, a crank-piston mechanism and a turbine generate mechanical energy transmitted to a generator for electricity production, which, in turn, is directed partially to heating elements installed in a boiler to generate heat, and partially for household needs. ;EFFECT: micro-thermal power plant (micro TPP) is obtained with high energy efficiency for cottages, dachas, small industrial premises and retail outlets.;1 cl, 1 dwg
