Abstract

PURPOSE: To enable to ignite surely all the time by a method wherein the damper in an air supply passage is closed after the finish of the prepurging period and the ignition does not be done until the closing of the damper is confirmed in the system for a combustion furnace in which the combustion is started after prepurging.
CONSTITUTION: A load driving control circuit 30, which sequentially controls the load containing a blower 41, a main valve 43, a pilot valve 44 and an ignitor 42, and an air supply control device 47, which controls the opening of the damper 37 to control the blast flow rate, are provided. At the side of the secondary winding 24 of a step-down transformer 21, a first electronic timing circuit, an air supply source control circuit and an ignition source control circuit (all these three circuits are not shown) are provided and also a secondary electronic timing circuit D and a flame detecting circuit are provided. And yet the circuits and the device described above are composed so as not only to sent out the signal to close said damper 37 after the finish of the prepurging period but also not to ignite until the actual closing of the damper 37 is confirmed.
