摘　　要：受热面积灰、结焦问题严重影响了垃圾焚烧余热锅炉的长期稳定运行。为采取合理、有效的清灰方式延长锅炉受热面寿命,开展了超频震波清灰技术在某660 t/d的垃圾焚烧锅炉二、三烟道内的应用试验,对比了不同清灰模式对于烟道温度变化情况影响。结果表明:在综合考虑清灰效果、清灰效益以及对工况的影响时,以普通模式按照1次/d频率进行清灰是最佳方案,长期使用可使二烟道出口烟气温度下降10℃左右、三烟道中部烟气温度下降40℃左右。本研究结果可为垃圾焚烧余热锅炉清灰技术的选择、应用提供参考,有助于实现其长期稳定运行的目标。The ash deposition and coking on the heating surface of a waste incineration boiler brings great challenges to the long-term stable operation.In order to take a reasonable and effective way of ash cleaning to extend the life of boiler heating surface,an experimental study of the shock pulse generators technology applied to clean ash in the second and third flue of a 660 t/d waste incineration waste heat boiler was carried out,and the effects of different ash cleaning modes on flue gas temperature were compared.The results showed that,in the comprehensive consideration of the ash cleaning effect,ash cleaning profit and the impact on the working conditions,operate normal mode at a frequency of once a day was the best plan,the outlet flue gas temperature of the second flue was reduced by about 10℃,and the flue gas temperature in the middle of the third flue was reduced by about 40℃during long-term application.The results of this study can provide a reference for the selection and application of ash cleaning technology for waste incineration waste heat boilers,which can help to achieve the goal of its long-term stable operation.
