WU Xiao-jun,LIU Ren-sheng,FANG Lian-zeng(Marketing Corporation of Lu'an Mine Group,Changzhi046204,China)By the trial-burn test of slime cws on the horizontal cylindrical burning furnace,the laws on the ignitability,combustibility,slag-bonding and release of pollutants of the slime cws were researched.The air distribution parameter,flame temperature,the temperature of stokehole and the carbon content of flying ash were tested.The technic measures about ignition and stable burning of the low volatile slime cws(V_ad=14.82%)were explored.The results show that the low volatile slime cws from Changcun mine can catch fire normally and burn stably,the highest burning temperature comes to above 1500 centigrade degrees,combustion efficiency is up to 97.22%.Because of the high combustion temperature of the slime,when designing boiler furnace,it should be considered how to reduce NO_x and prevent slag-bonding.
