摘　　要：在3.2 MW卧式炉中对污泥水煤浆和大同烟煤水煤浆进行了对比燃烧实验,分别研究了煤浆的着火、燃烧、结渣及污染物排放特性。结果表明,掺混10%污泥的水煤浆着火容易,燃烧稳定,炉膛火焰分布均匀,燃烧和结渣特性均优于大同烟煤水煤浆。污泥的添加使水煤浆燃烧烟气中SO2和NOx的浓度偏高,实际应用中可通过加入固硫剂等方式缓解。污泥水煤浆在卧式炉中的燃烧状况较理想,为城市污泥资源化利用提供了一条可行的新途径。Combustion tests of a sludge coal water slurry（S-CWS） and Datong bituminous coal water slurry（Datong bituminous CWS） were performed in a 3.2 MW horizontal furnace to investigate the industrial application feasibility of S-CWS.The properties of ignition,combustion,slagging and pollutant emission were analyzed respectively.The results indicate that S-CWS with sludge mass ratio of 10% can be easily fired and combusted stably.With better burning and slagging properties than Datong bituminous CWS,S-CWS produces ample flame in uniform distribution.The addition of sludge results in high concentrations of sulfur dioxide and nitrogen oxides in flue gas,which can be relieved by adding desulfurizing agents in practice.Generally,it is satisfactory to burn S-CWS in the 3.2 MW furnace,offering a new feasible method of sludge disposal.
