Abstract

PURPOSE: To accomplish extremely organic safety control for the sequence of a combustion apparatus by means of an electronic circuit mainly composed of four semiconductor switches.
CONSTITUTION: A forced-draft combustion apparatus is controlled in the operation sequence including prepurging, ignitor action, fuel feed valve action, stop and stanby at an abnormal combustion which occurs in the course of operation by means of the following: an electronic circuit composed of the first semiconductor switch SCR1 for protection at emergency whose function is backed by the third semiconductor switch SCR3 and accessaries, an electronic circuit at a start switch section including the fourth semiconductor switch SCR4 for regulating the action of the first semiconductor switch SCR1 and the action of the second semiconductor switch SCR2 composing a prepurging timing circuit.
