为研究3台老旧垃圾焚烧机组的运行性能，现场实测3台机组的主要运行参数，定量计算各项热损失，对比分析3台机组焚烧炉-余热锅炉及烟气净化设备性能。结果表明：A、B、C 3台机组实测焚烧炉-余热锅炉效率分别为77.44%，80.14%和82.70%，效率偏低的主要原因为燃用的生活垃圾热值高于机组设计垃圾热值导致排烟温度过高；机组各项热损失中，排烟热损失所占比例最大，其次为炉渣热损失；3台机组排烟热损失分别占总热损失的84.79%，74.21%及76.58%；B机组半干式反应塔漏风率最大（8.56%），C机组最小（2.90%）；3台机组布袋除尘器漏风率均偏大，分别为12.12%，6.54%及11.23%，远高于其设计值（2%）。

In order to study the operation performance of three aging waste incineration units,the main operation parameters of three waste incinerators were tested on site,each heat loss was calculated quantitatively,and the performance of incineratorwaste heat boilers and flue gas purification equipments of the three units was comparatively analyzed.The results show that the tested efficiencies of incineratorwaste heat boilers of units A,B and C are 77.44%,80.14% and 82.70% respectively.The main reason for low efficiency is that the calorific value of burned domestic waste is higher than that of designed unit waste,resulting that the flue gas temperatune is too high.Among the various heat losses of the units,the heat loss from flue gas accounts for the largest proportion,followed by the heat loss from slag.The heat losses from flue gas of three units account for 84.79%,74.21% and 76.58% of total heat losses respectively.The test results of air leakage rate show that the air leakage rate of semidry reactor in unit B is the largest,which is 8.56%,while that of unit C is the smallest,which is 2.90%.The air leakage rates of bag dust collector of the three units are all higher,12.12%,6.54% and 11.23% respectively,which are much higher than the designed value of 2%.
