PURPOSE: To render to automatically stop a blower in order to stop prepurging during steady combustion by a method wherein an ignitor driving signal and a fuel valve driving signal are made into AND signals in the combustion controlling device employed in a pulse combustor.
CONSTITUTION: Because an output terminal 2a for a compressor goes to the low level when the temperature of the load lowers, a transistor 12 is ON and, immediately after that, a capacitor 10 is charged to raise the output of a comparator 11 to the high level, resulting in turning a transistor 13 ON and then a relay 13 is ON to start prepurging. After the elapse of the predetermined period of time, output terminals 2b and 2c go to the low level to turn relays 4 and 5 ON in order to start ignition action. Simultaneous with the ignition or after the ignition timing is expired, the output terminal 2b for ignitor goes to the high level in order to stop the operation of the ignitor, while the output terminal 2c keeps the low level. Consequently, a transistor 14 is made ON and the transistor 13 is made OFF, resulting in turning the blower relay 3 OFF to stop the blower and to operate the device in steady combustion state.
