Abstract

PURPOSE:To prevent flame lifting and burning with yellow flames, as of a burning device which is designed to control fuel combustion amounts through the regulation of the number of the blower motor revolutions and the pulse frequency, by forming an integration circuit for the purpose of change-over of the pulse oscillator frequency so as to make the frequency change-over slow-acting. CONSTITUTION:An integration circuit consists of resistors 16-21, the capacitor 22 and the operational amplifier 23, thus enabling the gate potential at the PUT12 to change slowly. With the selector switch 8 open under ''low'' signal condition, the gate potential at the output PUT12 of the operational amplifier 23 is determined by the resistors 18 and 19. With the selector switch 8 closed under ''high'' signal condition, the blower motor (not shown in the diagram) gradually begins to turn at high-speed, and the output of the operational amplifier 23 drops to the levels of potential as determined by the resistors 18, 7 and 19. This change-over process, via the integration circuit consisting of the resistors 20 and 21 and the capacitor 22, is made slow-acting. In this way, flame lifting and burning with yellow flames, which are liable to occur under the aforementioned change-over process, are prevented.
