The paper presents development and validation of coal mill model (including the action of classifier) to be used for improved coal mill control. The model is developed by using the mass and heat balance equations of the coal mill. Genetic Algorithm is used to estimate the unknown parameters that are used in the model validation.

Pulverized coal were sampled isokinetically from the PC pipes. there is a significant maldistribution of coal mass flow in the PC pipes. The particulate size was also coarse. the heat release from the combustion of coal occurred higher up in the boiler, leading to a flue gas exit temperature.
