A liquid fuel power plant (100) including an open-ended combustion chamber (102) and a first mechanism (112) for delivering a combustible fuel to the open-ended combustion chamber (102). A second mechanism (136) is included for igniting the fuel in the open-ended combustion chamber (102). A coiled tube-shaped mechanism (140) located within the combustion chamber (102) is provided for extending the length of the combustion chamber (102) to decompose the ignited fuel and to provide an exhaust gas comprised of fundamental elements. Finally, a third mechanism (160) is provided for using the exhaust gas to perform useful work. In a preferred embodiment, the liquid fuel power plant (100) includes separate fuel and air input lines (110, 120). The air input line (120) delivers compressed air which is preheated in an air passageway (130) and thereafter mixed with the combustible fuel in the open-ended combustion chamber (102). An igniter (136) causes combustion of a compressed air-fuel mixture in an ignition region (118) of the combustion chamber ( 102) . The residue of the combusted air-fuel mixture is thereafter forced by the compressed air into the coiled tube-shaped extension (140) which forms a reaction region (166) of the combustion chamber (102). The reaction region (166) becomes sufficiently hot to ensure complete decomposition of the combustible fuel. The hot pressurized exhaust gas, which is very low polluting, is directed by an exhaust tube (158) to a load such as a turbine (160).
