Gas burner for heater has ionisation electrode in flame producing signal related to flame temperature which is passed through two control systems, one of which produces output with higher amplification and smaller time constant than other

摘要

The gas burner for a heater has an ignition burner and an automated firing monitor (4). An ionisation electrode (3) positioned in the flame produces a signal related to the flame temperature or lambda value. This is passed through two control systems (1, 2), one of which produces an output with higher amplification and a smaller time constant than the other. The signals are then passed to the monitor.
