Abstract

PURPOSE: To improve the combustion efficiency by a method wherein the controlling device is made up so as to output the command signal for starting the combustion at the low level of the proportional combustion range.
CONSTITUTION: Proportional controlling is performed by rotating a motor 5 on the speed based on the output of a proportional combustion controlling circuit 50. When the command for starting of the combustion is issued by the operations of a controlling circuit 20 and a combustion controlling circuit 30 due to the state that the stop of the combustion results the lowering of the load temperature, a contact 41a is closed to rotate the motor 5. At this time, because the output of the proportional combustion controlling circuit 50 is shorted at a transistor 48, the output of the comparator 66 of a minimum rotational frequency compensating circuit 60 is high level and as a result a transistor 72 is on and then a minimum rotational frequency compensating signal is supplied to a photocoupler 80 to rotate the motor 5 on the mimimum speed. After the elapse of time for prepurging, a relay 42 is on to operate an igniter in order to start the combustion. Accordingly, the improvement of the combustion efficiency is contrived by starting the combustion at the low level of the proportional combustion range.
