淮北朔里煤矿经过反复试验,成功地将锅炉燃烧后的炉渣再次加工成型煤,供生活用。一、炉渣应用的背景该矿在1990年以前由于技术管理上的综合原因,锅炉燃烧效率低,有6400t炉渣燃烧不完全。据测定,炉渣含碳量达35％,发热量12.91MJ/kg。该矿经认真调查研究后将炉渣、无烟煤、黄泥,以67:20:13的比例,加水掺和后,用125型煤球机加工成型煤,再通过反复燃烧试验,从上火速度、热量供给等实测参数证实,能够满足生活煤要求。检验结果炉渣掺入无烟煤后(不含黄泥成分)发热量19.03MJ/kg,而本矿生产的原煤仅22.95MJ/kg,进一步证实加工型煤
After repeated tests in Huaibei Shuoli Coal Mine, the slag after combustion of the boiler was successfully processed into briquette for domestic use. First, the background of slag application The mine in 1990 due to the technical management of the integrated reasons, the boiler combustion efficiency is low, there is incomplete combustion of 6400t slag. It is determined that the slag carbon content of 35%, calorific value 12.91MJ / kg. The mine after careful investigation and research will be slag, anthracite, yellow mud to 67:20:13 ratio, add water after mixing with 125 briquettes machine molding coal, and then through the repeated burning test, from the speed of ignition, heat Supply and other measured parameters confirmed that to meet the living coal requirements. Test results after the slag incorporation of anthracite (excluding yellow clay composition) heat 19.03MJ / kg, while the mine only 22.95MJ / kg of raw coal, further confirmed the processing of coal
