Abstract

PURPOSE:To control the supplying amount of fuel gas within a wide range, by a method wherein a solenoid valve and proportional valve control circuit is controlled stepwisely in accordance with a predetermined blasting amount based on a signal from a blasting amount detecting means to control the supplying amount of fuel gas, supplied from a nozzle to a burner. CONSTITUTION:The supplying amount of combustion air is detected by a rotating number detecting circuit 32 (blasting amount detecting means) and the signal thereof is sent to a sequence control circuit 34. The control circuit 34 controls a switching solenoid valve 22 to open the same when the supplying amount of combustion air is more than a predetermined supplying amount but close the same valve 22 when the supplying amount of combustion air is less than the predetermined supplying amount. When the solenoid valve 22 is opened, fuel gas, injection from a nozzle 21, passes through the solenoid valve and an orifice, however, when the solenoid valve 22 is closed, the same gas passes through only the orifice. In this case, the control circuit 34 controls a proportional valve control circuit 33 also to change the amount of conduction of a governor proportional valve 25 whereby the supplying amount of the fuel gas is controlled.
