Patent attributes
Combined apparatus for heating a fluid and for producing electrical power is comprised of a burner operable to burn a combustible fuel-air mixture to produce gaseous products of combustion; a heat exchanger adapted to receive the products of combustion and to transfer heat therefrom to the fluid; a gas-operated turbine; and an electrical generator that is co-rotatable with the turbine. In operation, gaseous products of combustion are introduced into the turbine after they have passed through at least a portion of the heat exchanger. The products of combustion expand in the turbine to rotate the turbine, which in turn rotates the generator to produce electrical power. The apparatus further includes a compressor that is co-rotatable with the turbine and generator to provide combustion air to the burner and to circulate the products of combustion through the heat exchanger and turbine.
