<p>A reciprocating piston generator assembly that uses a low-concentration methane as a form of fuel comprises: a lean methane engine; a generator assembly; a fine water mist transmission system; a refrigerating dehydrator; an electric butterfly valve; a pressure regulator; a fuel-air mixer; a TEM controller; a heat load sensor; a combustion chamber for the lean methane engine; an air filter; and a speed governing butterfly valve, wherein the fine water mist transmission system is attached sequentially with the refrigerating dehydrator, electric butterfly valve and low-concentration methane engine; and the pressure regulator, fuel-air mixer, air filter, speed governing butterfly valve, heat load sensors and combustion chambers are installed in the methane engine; that the TEM controller is connected to the fuel-air mixer and heat load sensor; and the generator is connected to the low-concentration methane engine. This invention has been applied broadly in low-concentration methane coal mines and other similar fields due to its favored properties; such as high heat-recovery efficiency, lessened water consumption, energy savings, emission reduction and environmental protection.</p> |
