本文根据新型燃煤喷枪冷态试验的结果,对Ⅱ型和Ⅰ型喷枪与基准枪进行了热模对比试验。试验表明在等同燃烧条件下,Ⅱ型和Ⅰ型喷枪的燃烧结果均优于基准枪,尤其在喷吹烟煤、煤粉粒度变粗、风温下降和喷煤量增加的情况下,前者优势就更明显。 According to the result of the cold test of the new type of coal-fired lance, the comparison between the type I and type I lances and the reference lances was carried out. The results show that under the same combustion conditions, the combustion results of type Ⅱ and type Ⅰ lances are better than those of the reference lances. Especially when bituminous coal is injected, the particle size of the coal particles becomes coarse, the temperature of the air drops and the amount of coal injected increases, More obvious.
