Abstract
PURPOSE: To make a flame spread perfecty and to enable a safe combustion, by a method wherein an ignition is performed with a small amount of gas, and after ignition, a gas amount is caused to increase rapidly.
CONSTITUTION: With a main valve 4 and a water valve 7 opened through the operation of a control 5, an ignition circuit 6 starts to ignite a pilot burner 2. When flame is confirmed by a detecting circuit 10, the ignition circuit 6 suspends operation, and an output circuit 11, in turn, starts actuation. If flame is detected, a transistor Tr1 in a signal circuit 11A is energized, and output of a capacitor C2 is transmitted to a valve drive circuit 12 from a EET gate F1 through a noninversion amplifying circuit 11C. An electromagnetic type proportional valve 3 is opened, and if a time constant by a resistor R2 and a capacitor C2 is set at 1W2sec, the output of the output circuit 11 becomes an output which sharply rises from 0 to a maximum. The valve drive circuit 12 is also actuated in the same manner by means of the output, and the electromagnetic proportional valve 3 is quickly released from a closing to a full opening.
