Online Ash Fouling Prediction for Boiler Heating Surfaces ...

Depending on its operating conditions traditional soot blowing is activated for a fixed time. However low-frequency soot blowing can cause heat transfer efficiency to decrease. High-frequency soot blowing not only wastes high- steam but also abrades surface pipes reducing the working life of a heat exchange device. Therefore it is necessary to design an online ash fouling ...
