ABSTRACT:
A combined heat and electricity generating unit is suitable for use in single family homes and the like. When it is operating it provides heat for heating the home and electricity for use by the electricity consuming devices in the home and the excess is available for sale to the power utility. It includes an air compressor, a fuel pump, a turbine driven by heated combustion products and an electric motor-generator for driving the fuel pump and air compressor and converting energy produced by the turbine to electricity. In an alternate embodiment the electric motor-generator is replaced by an electric motor and an electric generator. In the case where gaseous fuel is used the fuel pump may be a positive displacement gas compressor. The pressurized combustion products enable a particularly efficient and inexpensive heat exchanger. The air compressor maintains a slight vacuum in the housing thereby eliminating risk of combustion products escaping.
