Filed: 1979-08-31
Abstract: PURPOSE: To reduce the power to be supplied to a heater for heating a vaporizer after starting combustion by adopting a combustion system in which a spray nozzle and the vaporizer are combined to obtain a large combustion quantity and a quiet combustion sound and providing the vaporizer in the proximity of one wall surface of a combustion chamber.  
     CONSTITUTION: After the electric current is applied to a heater 5 to heat the vaporizer 4 to a predetermined temperature, a blower 3 is driven to supply combustion air through an air feed hole 11 into a mixing chamber 7, and a fuel supply pump 2 is driven to spray fuel through a nozzle 1. Upon this occasion, fuel comes into collosion with the vaporizer 4 and is gasified, and mixed with combustion air thus entering the combustion chamber 7. In the combustion chamber 7, a gaseous mixture of fuel and air flows out of a flame hole plate 9 as it increases the mixing degree by a mixing promoting plate 8, and ignited by pilot flame 10, thus burning within the combustion chamber 6. After starting the combustion, the peripheral wall of the combustion chamber 6 is heated, and the temperature of vaporizer 4 increases. Therefore, the power to be supplied to the heater 5 is reduced, and economization of power is attempted.
