Abstract
A combustion chamber of a pulsating combustor is supplied with fuel from a fuel-supplying system and with air for combustion from an air-intake chamber through an air-intake pipe. The air-intake pipe is interiorly provided with an aerodynamic valve having a forward flow coefficient greater than a flow coefficient in a reversed direction. An air-supplying fan controlled by a combustion control unit is connected to the air-intake chamber. A fuel control valve for varying the amount of fuel supplied to the combustion chamber is connected to a fuel-supplying pipe of a fuel-supplying system. When a mixture gas within the combustion chamber is fired at the start of a pulsating combustion system, the combustion control unit rotates the air-supplying fan at high speed to forcibly feed air for combustion into the combustion chamber. When the fuel control valve is operated in order to vary the combustion power, the combustion control unit rotates the air-supplying fan in the rotational direction and at the rotational frequency corresponding to the amount of fuel varied thereby to feed air for combustion into the combustion chamber to realize an optimum ratio of fuel to air for combustion.
