摘要：

A mechanism model of coal pulverizing system is developed to calculate the coal powder flow rate entering the combustion chamber with the data of a 300MW coal-fired power plant. This model is going to be used to improve the identification accuracy of the calorific value, which usually takes the coal flow rate entering the coal feeder as the input. The model parameters are based on the structural and operational data of the pulverizing system. Results of the pseudo online identification of the caloric value demonstrate that the model can capture the dynamic properties of the system with relatively high accuracy. Therefore, there is potential application of this model to improve the control performance of the utility boiler.
