摘要：

为了实现火电燃煤锅炉各受热面污染程度的在线监测以及吹灰的优化运行,本文以省煤器为研究对象,基于热量平衡的原理,以清洁因子为受热面污染程度的衡量指标,建立了省煤器受热面的灰污模型。该模型考虑了变工况的影响,并在模型中增加了辐射换热子模块。最后利用离线数据对模型进行计算,验证了该模型的合理性。

Abstract:

For the purpose of realization of ash deposition monitoring and optimal operation of sootblowing,taking the economizer as the research object and the cleanliness factor as the measurement of the degree of pollution of heating surface,based on the principle of heat balance,a model of heating surface ash deposition was being established.The model considered the impact of changing conditions,and added radiation heat transfer as sub-module.Finally,with offline data to calculate the model,it is verified that the model is reasonable.

Key words: engineering of energy sources system, economizer, ash deposition, monitoring model, soft measurement
