It is confirmed that, the operation level of stoker boilers can be improved such as enhancing the combustion intensity, boiler thermal efficiency and flue gas temperature of furnace outlet.

证实了炉内增拱可较大的提高炉内燃烧强度，提高抛煤机锅炉的热效率和炉膛出口烟温。

These will result in local heat accumulation at the outlet of burner, very high temperature of flue gas, uneven distribution of temperature in furnace and damage of nozzles.

这将导致燃烧器出口处热量局部聚集，烟气温度非常高，造成炉内温度分布不均及喷嘴的损坏。
