FIELD: anaerobic power plants. SUBSTANCE: hydrogen source of anaerobic power plant is, essentially, hydrogen-producing system based on metal hydride. Engine cooling circuit has pump, heat exchanger- cooler and is passed through heat exchanger-heater of closed-circuit heating loop of hydrogen producing system. Combustion product outlet line is passed through Stirling engine heater, steam superheater, and steam generator of steam ejection refrigerator to provide communication between combustion chamber and condensate storage tank. Closed-circuit heating loop of hydrogen producing system has pump, heat exchanger-heater, and electric heater. EFFECT: extended life of engine heater, increased output of low- potential energy for cold supply to specific equipment. 1 dwg
