| Abstract: | The predicting model of ash fouling on heat transfer surfaces of utility boiler is proposed. The characteristic of heat-transfer resistance of ash deposit and the effect of flue gas velocity are discussed. The model is compared with experiment data of a 300MWcoal-fired boiler and themodel parameters are obtained. The results are contributed to improve sootblowing optimization model and sootblowing strategy. |

| Keywords: | ash fouling model aggradation rate denudation rate sootblowing optimization |
