ことを特徴とした炎検知回路。 A combustion amount switching control circuit C that switches the combustion amount into a plurality of stages, a first timer element A-1 and a second timer element A-2 that are activated by the output thereof and have different time until the start of operation, and their output and combustion. Each flame detection circuit B is provided to compare the flame detection output and output a control signal, and when the combustion amount switches to an increasing direction, the first timer element A-1
The flame detection circuit is characterized in that the flame detection sensitivity is switched by the output of the second timer element A-2, and by the output of the second timer element A-2 when the combustion amount is switched to a decreasing direction.
