Due to the deviation of burning coal type from design coal type, there are some problems in the actual operation of 220 t/h anthracite boiler, such as unstable combustion, frequent fire extinguishing, and high residual carbon content in the ash. By laying refractory belts on the fire side and back fire side of the boiler burner, the combustion stability of the boiler is greatly improved without obvious coking, and the problem of flameout due to unstable combustion is completely solved.
