Abstract

A pulsing combustion device including a combustion chamber having an inlet for combustible mixture and an unvavled outlet open to the atmosphere for combustion gases, a floating valve member mounted in reciprocation relation in the wall of the combustion chamber, the reciprocation of the floating valve closing and opening communication through ports between the supply of combustible mixture and the combustion chamber. The floating valve may be annular shaped with an ignition means extending through a central portion of the end of the combustion chamber. The pulsing combustion device may be used as an air heater by providing an exhaust manifold passing the combustion gases through a closed heat exchanger over which treatment air is passed through an air treatment duct. The pulsing combustion device may be provided with a pressurized combustion air flow regulator providing higher pressure combustion air to a lower pressure combustible mixing chamber to which fuel gas is added.
