摘　　要：医疗垃圾是一种对环境危害极大的危险废弃物。用一种固定炉排炉热解焚烧系统,对广州市部分医院的医疗垃圾进行了热解焚烧及尾气净化试验,并对焚烧工况、烟气中主要的污染物含量及灰渣的灼减率进行分析。分析结果表明:稳定运行时炉膛平均温度在850℃左右,二燃室平均温度在1000℃以上;尾气中CO、NOx、HC l和SO2浓度分别为:71mg/m3、125 mg/m3、27.8 mg/m3和21 mg/m3,灰渣的灼减率为2.7%。均远远低于标准限值。A fixed fire grate system for pyrolyis and incineration of medical wastes is introduced in this paper. Its main components include pyrolysis and incineration furnace, heat exchanger heat pipe, cooling tower and bag-type dust collector. The test results indicate that the average temperatures in furnace chamber and second furnace room are about 850℃ and 1000 ℃ ,respectively. The concentrations of CO,NO, ,HC1,SO2 in off gas are 71 mg/m^3, 125 mg/m^3 ,27.8 mg/m^3 and 21 mg/m^3 respectively, all the values are much lower than that of standard limitation.
