摘要：PURPOSE:To reduce unburnt gas in a burner, by a method wherein the feed rateof kerosene, supplied by an electromagnetic pump, is reduced than the one during weakcombustion and a combustion flame is brought into close contact with the burner to heatthe burner to a high temperature when a control circuit receives a fire extinguishingsignal, then, the control circuit stops the operation of the electromagnetic pump when apredetermined time has elapsed. CONSTITUTION:When a fire extinguishing signal isinputted into a relay control circuit 24, the input voltage of a V-F converting circuit 45becomes low and an electromagnetic pump 12 supplies kerosene, whose amount is farsmaller than the same upon weak combustion. Accordingly, only the supplying amount offuel is reduced than a normal combustion range to make air excessive while combustionflame is brought into close contact with a burner head 9 to heat the main body 6 of aburner to a high temperature. When 7 seconds, for example, has elapsed under thiscondition, a timer 47 outputs a time-up signal to a relay control circuit. Then, the relaycontrol circuit 24 stops the driving of the pump 12 to stop the supply of kerosene.However, the temperatures of the burner head 9 and the main body 6 of the burner arehigh and the remaining gas of an evaporating chamber 7 continues to burn, therefore, the

amount of discharging of unburnt gas into a room may be reduced remarkably.
