工业锅炉是国民经济和人民生活中不可缺少的重要热能动力设备,又是能源消耗的第一大户。我国无烟煤储量丰富,约3600亿吨,仅次于烟煤,但又是碳化程度最高、挥发份最低的一个煤种,尤其是Ⅱ类无烟煤挥发份极低(V~5<5％)、着火点高(900℃以上),煤沫比例大(0～3mm占70％以上),是一种不容易着火又极难燃烬的煤种,在燃烧技术上是一个难题。 Industrial boilers are indispensable to the national economy and people’s livelihood, thermal power equipment, but also the largest energy consumption. China’s anthracite reserves are about 3600 billion tons, second only to bituminous coal, but it is also one of the most carbonated and least volatile coal types. In particular, Class II anthracite has very low volatility (V5 <5%) and high ignition point (900 ℃ above), a large proportion of coal foam (0 ~ 3mm accounted for more than 70%), is not easy to fire a very hard coal burning embers, combustion technology is a problem.
