煤泥是湿法选煤工艺过程中产生的粒度小于0.5毫米的副产品,由于灰份高,含粘土物质多,热值低,持水性强,商品价值低,处理困难。大量煤泥堆积占地面积大,还造成严重的环境污染,预计到1900年入选原煤将达2亿吨左右,煤泥产率按6%计算,则每年排放煤泥1200万吨左右,如能将煤泥直接用作工业锅炉或动力锅炉的燃料,无疑是一种最佳的处理方法。浙江大学燃烧教研组设想用沸腾燃烧方式处理煤泥,为此开展了煤泥沸腾燃烧技术的研究。本文所述即是该研 Slime is a byproduct of particle size less than 0.5 mm produced during the wet coal preparation process. Due to the high content of ash, many clay-containing substances, low calorific value, strong water holding capacity and low commodity value, the treatment is difficult. Large amount of slime accumulation area, but also cause serious environmental pollution, is expected to be selected by the 1900 coal will reach 200 million tons, slime yield calculated at 6%, the annual discharge of 12 million tons of slime, if Using slime directly as fuel in industrial boilers or power boilers is undoubtedly the best treatment. The combustion teaching and research group of Zhejiang University envisaged the treatment of slime by means of boiling combustion and carried out research on the slime combustion technology.
