摘　　要：通过在卧式圆筒形燃烧炉上对煤泥水煤浆进行试烧实验,研究煤泥水煤浆的着火、燃烧、结渣以及污染物排放等规律,测试配风参数、火焰温度、炉膛出口温度和飞灰含碳量等特性参数,摸索低挥发分(Vad=14.82%)煤泥水煤浆的着火稳燃技术措施。实验结果表明,常村这种低挥发分煤泥水煤浆能在工业炉内正常着火和稳定燃烧,最高燃烧温度能达到1500℃以上,燃烧效率97.22%;由于此种水煤浆燃烧温度较高,设计锅炉时应考虑采取降低NOx和防止结渣措施。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（ Vad = 14. 82% ）were explored. The resuits 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 NOx and prevent slag-bonding.
