FUEL BURNER CONTROL SYSTEM WITH HOT SURFACE IGNITION

摘要

A gas burner control system includes an electrical resistance igniter (26), gas valve means (32, 34), and a microcomputer and related circuitry. The microcomputer and related circuitry control energizing of the igniter (26) in such a manner so that the igniter (26), after successive ignition attempts, will eventually, in response to a learning routine, be heated to a desired ignition temperature. The microcomputer and related circuitry also control operation of a circulator blower in response to burner flame (42) and provide for numerous checks on the integrity of system components.
