根据新型燃煤喷枪冷态试验结果，对Ⅱ型、Ⅰ型与基准枪进行了热模对比试验，结果表明：在等同燃烧条件下，Ⅱ型、Ⅰ型喷枪的燃烧结果均优于基准枪，尤其当喷吹烟煤、煤粉粒度变粗、风温降低和增加喷煤量时，前者优势更加明显．富氧（1．2％）及无烟煤中混入烟煤（10％）亦能提高煤粉燃烧率；在本试验范围内其效果均低于新型燃煤喷枪． According to the results of the cold test of the new type of coal-fired lance, the comparison between the type Ⅱ and type Ⅰ with the reference gun was carried out. The results show that the combustion results of type Ⅱ and type Ⅰ lances are better than that of the reference lance under the same combustion conditions, Especially when the injection of bituminous coal, coal particle size becomes coarse, the wind temperature decreases and increase the amount of coal injection, the former advantage is more obvious. Oxygen enrichment (1.2%) and anthracite mixed with bituminous coal (10%) also increase the rate of pulverized coal combustion, which is less effective than the new coal fired lance within the scope of this test.
