Patent ID: 8753876

Claim:
A method of recycling thermal energy from a boiler, comprising: coupling a thermal gas conduit from a burner component of the boiler to a biomaterial cooker and a bioreactor, wherein the bioreactor comprises an anaerobic fermenter and an aerobic composter; directing a combustion gas through the thermal conduit from the burner through the biomaterial cooker and the bioreactor to form a thermal gas cycle; recovering liquid by-products from the conduit and the boiler; directing an acidic portion of the liquid by-products through the biomaterial cooker and a basic portion of the liquid by-products through the bioreactor to form a thermal liquid cycle; recovering the acidic portion and the basic portion of the liquid by-products from the biomaterial cooker and the bioreactor; and returning thermal energy to the burner and the boiler from the thermal gas cycle and the thermal liquid cycle to reduce emissions and fossil fuel consumption in the operation of said boiler.
