为了考察黑液水煤浆工业应用的可行性,在0.25 MW试验炉上对新汶良庄矿常规和黑液两种水煤浆作热态对比试验以研究煤浆的流动、雾化、着火、燃烧、沾污结渣及污染物排放特性.借助自制灰污热流计分析了两种煤浆的沾污结渣趋势.结果表明,相对常规浆而言,黑液浆具有良好的流动、雾化性能,着火容易,燃烧稳定,还具有低污染排放,低灰熔点、强结渣的特点.故黑液水煤浆在电站锅炉和工业锅炉中应用是可行的.
In order to investigate the feasibility of industrial application of black liquor CWM, two kinds of conventional and black liquor coal water slurries in Xinwenliangzhuang coal mine were compared in a thermal state to study the flow, atomization and ignition of coal slurry , Combustion, fouling and slagging, and pollutant discharge characteristics were analyzed.The tendency of fouling and slagging of two kinds of coal slurries was analyzed by means of a self-made fouling heat flow meter.The results showed that the black liquor had good flow and fog It has the characteristics of easy ignition and combustion, low emission, low melting point and strong slagging, so it is feasible to use black liquor CWM in power plant boilers and industrial boilers.
