摘　　要：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.Thermal state comparative test between the normal coal water slurrry(CWS) and black liquor CWS from Xinwen was performed in 0. 25 MW furnace for the purpose of investigating the industrial application feasibility of black liquor CWS. Performances of flow, atomization, kindling, burning, fouling, slagging, and pollutant emission were researched. The fouling and slagging tendency for two CWSs were analyzed by using a self-made heat flux meter. The results show that the black liquor CWS is a fuel with good flowability and atomization, easy firing, stable burning, low pollutant emission, low ash fusion point, and strong slagging tendency, in contrast with the normal CWS. So it is feasible for the black liquor CWS to be used in industrial boilers.
