Abstract

PURPOSE: To provide a combustion detecting circuit wherein operations are highly stable and sure, an adaptable range for resistances of flames is wide and safety is high, by constituting the circuit in a type of an oscillating circuit.
CONSTITUTION: In a combustion detecting circuit, consisting of a flame detecting signal circuit A, an oscillating circuit B, a switching circuit C, an AC coupling means D and a rectifying circuit E, circuits B1WB5, effecting same functions as the oscillating circuit B, are provided. The circuit B1 is a switching means, being connected when a terminal voltage of a condenser 4 is arrived at a predetermined level due to receiving flame signal voltages. The circuit B2 is a timer circuit operated when the switching means B1 is connected. The circuit B3 is a voltage comparator having predetermined reference voltage and hysteresis. The circuit B4 is a reset circuit for resetting a condenser 35 in the circuit B2, and the circuit B5 is a stopping circuit for disconnecting the switching means B1.
