ANAEROBIC POWER PLANT BASE ON STIRLING ENGINE Russian patent published in 1997 - IPC

FIELD: power and transport engineering. SUBSTANCE: exhaust gases are fed to a system for producing artificial gas mixture 2 from combustion chamber 7 of Stirling engine 1. Being reacted with alkaline-earth metal a great amount of heat is produced and gas is synthesized. The synthesized gas is then used as a fuel for engine 1. The synthesized gas of high thermodynamic potential enters heater 17 of additional Stirling engine 3 where it supplies heat to fluid allowing a thermodynamic cycle to be executed in additional engine 3 thus producing a useful work. Liquid oxygen is supplied from tank 20 by pump 21 to coolers 9 and 19 where it cools fluid of engines 1 and 3 up to a temperature lower than that of environment. EFFECT: enhanced efficiency. 1 dwg
