Abstract

Abstract:

Aiming at serious boiler slagging and extinguishing of the 300MW subcritical unit in a power plant, combining with the boiler structure features,

the coal characteristics and the actual operation situation, the main reasons causing the boiler slagging were analyzed. Some targeted control measures for

preventing the boiler slag falling and extinguishing, such as the coal management, the oxygen adjustment and others, were proposed. After the measures

adopted, obvious slagging of the boiler was eliminated; and favorable effect of the control measures was obtained.

Key words: slagging, fire extinguishing, refractory belt, leveling of primary air
