A district heating system is described, for heating several homes and businesses in a district. The hot exhaust gas, of a gas turbine engine, is saturated with water vapor, and then passed through each home heater, where condensation of the water vapor provides heat to each home. With low cost coal fuel, burned in the gas turbine engine burner, a large portion of the fuel energy is efficiently utilized for home heating and electric power generation. In this way, low cost domestic coal can replace expensive imported petroleum fuels for home heating and electric power generation.
