Abstract

Abstract: Lowering coal quality will influence the stability of combustion seriously, and unstable combustion causes the significant changes of wall temperature in furnace and water level fluctuation in drum. This will led to the flame out not only during high-load operation, but also in stoppage process, which the unit has to shut-down unnormally because of big block of slag. The combustion conditions of #1, #2 and #4 boiler were compared with that of #3 boiler. The questions left over in burner reformation were analyzed and synthesized combining with the change of coal quality and the operation status of each burner. The reason of abnormal combustion condition of #3 boiler was finded out.

Key words: furnace flame failure and slagging, stable combustion, burner reformation, reason analysis
