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
