A process for pulse combustion in a horizontal pulse combustor having at least one air inlet flapper valve, at least one fuel inlet flapper valve, a combustion chamber, and a plurality of downstream combustion chamber branches in which each is in communication with a plurality of downstream exhaust tubes. The process includes the steps of introducing air through the air inlet flapper valve into a mixing zone. Fuel is introduced through the fuel inlet flapper valve into the mixing zone. A combustible fuel/air mixture is formed within the mixing and ignition chamber and is ignited there to complete combustion within the combustion chamber. Combustion product gases are exhausted through the combustion chamber branches and further exhausted through the exhaust tubes.

A flapper control valve having a valve housing and at least one valve port plate sealably secured to the valve housing. Each valve port plate has at least one valve port plate through hole. At least one back plate is mounted downstream from the valve port plate and in an open position at a distance from the valve port plate. Each back plate has at least one back plate through hole. In the open position, at least one valve port plate through hole is in communication with at least one back plate through hole. The distance between the back plate and the valve port plate in the open position can be closed thus sealing the communication between at least one valve port plate through hole and at least one back plate through hole.

A pulse combustor having a combined mixing and ignition chamber in communication with a fuel inlet tube and an air inlet tube. The fuel inlet tube and air inlet tube inject fuel and air, respectively, forming a fuel/air mixture in the mixing and ignition chamber. An ignition source for igniting the fuel/air mixture is located within the mixing and ignition chamber. A main combusiton chamber is sealably secured to the main combustion chamber wall and in comunication with the mixing and ignition chamber. The main combustion chamber first splits into a plurality of downstream combustion chamber branches, each of which further split into a plurality of exhaust tubes. The combustion chamber branches of the main combustion chamber have a slot between the combustion chamber branches. At least one reinforcing strut is secured between the combustion chamber branches within the slot between the combustion chamber branches of the main combustion chamber. A plurality of exhaust tubes each have a chamber end in communication with the main combustion chamber and/or combustion chamber branches.

This invention relates to a flapper check valve having a valve housing which has at least one outlet opening. A valve backer plate having a plurality of arcuate backer through holes is positioned generally parallel to a valve port plate having a plurality of arcuate port through holes. The valve port plate and valve backer plate are sealably secured with respect to the valve housing. In an open position of the flapper check valve, the backer through holes are in communication with the port through holes. At least one peripheral spacer/hermetic seal is positioned at a generally peripheral location relative to the valve port plate. Upon combustion within the combustion chamber, the flapper check valve prevents fluid/gas backflow in a direction from the valve backer plate to the valve port plate. At least one flat central spacer is positioned at a generally central location relative to the valve port plate and the valve backer plate. A plurality of inner spacer/guide pins are positioned on an interior surface of the valve port plate.
