摘　　要：进行了电站锅炉受热面污染监测的研究,主要针对锅炉炉膛辐射受热面结渣的问题,采用炉膛清洁因子作为灰污监测模型,基于声学测温技术直接测量炉膛出口烟温,并且通过热力计算和结渣分析,建立炉膛出口烟温、炉膛清洁因子、结渣状态三者之间的对应关系,由清洁因子的数值判断炉膛结渣状况。计算分析结果表明,炉膛清洁因子模型能够达到有效的炉膛结渣实时监测,作为判定指标帮助实现电站锅炉的吹灰优化运行。This paper studies power station boiler furnace pollution monitoring. To solve the slagging problem, we used clean factor for fouling monitoring model and acoustic temperature measurement technology, through the thermodynamic calculation and analysis of the results; established the relations between the chamber exports smoke temperature, cleaning factor and the furnace slag state. Then achieved the effective furnace slag and real-time monitoring, helping to achieve power station boiler blowing optimization operation.
