Causes for Flame Failure in a Boiler and Operator

2020-9-24 · Maintaining a good flame in a boiler is the key to a good boiler performance. Unstable flame is always a threat for boiler furnace explosion, which can lead to a large outage of boiler and loss. There are many causes that can contribute to boiler flame failure. Hence it has become a practice of all boiler designers to interlock purging the boiler with boiler start-up.

The National Board of Boiler and Pressure Vessel

The summer shutdown period is a good time to accomplish necessary boiler and fuel burning system preventive maintenance. A suggested check list of such maintenance follows: Drain and flush the boiler, open all handholes and manholes, clean and remove soot and scale from the firesides. Examine the boiler for damage and corrosion.
