摘要
针对空气预热器吹灰优化问题,提出以受热面清洁因子的计算来确定吹灰的起始时间,推导了清洁因子的计算方法,论述了清洁因子与受热面污染状况的关系。开发了吹灰优化系统,通过监测清洁因子的变化来确定受热面是否需要进行吹灰,当清洁因子达到最佳值时停止吹灰。
Regarding the sootblowing optimization for air preheaters, a method has been proposed to determine the start time of sootblowing based on calculated cleanness factors. Specific calculation way of cleanness factor has been deduced, while relationship between the cleanness factor and actual heating surface contamination analyzed. An optimized sootblowing system has been developed, by monitoring the variation of cleanness factor, so as to determine when to start or stop the sootblowing operation.
