  • Biogas driven generator set
    Patent number: 5724948
    Abstract: A generator powered by an internal combustion engine is fueled from a source of biogas. The biogas flows through a filter which removes hydrogen sulfide and mercaptans and through a coalescer to remove water vapor. A regulator controls the biogas pressure supplied to the fuel intake of the engine carburetor, and acid-neutralizing oil is injected into the engine intake each time the engine is shut down to protect the engine from acidic constituents in the biogas.
