approaches to coal mill modelling use heat balance, mass balance and thermodynamic laws [2–4], but those models are basically linear and cannot be utilised in the present day complex scenario of varying load on the power plants and varying coal quality. In [5, 6], non-linear models have been proposed for the entire coal mill process but this ...

A coal with higher GCV means less coal flow and vice-versa. More coal flow means more volume of air to be handled by the ID Fan, which ultimately affects the power consumption from the ID Fans. Due to change in coal quality there may rise a need of starting or stopping a mill. This affects the percentage APC significantly. Again, the quality of ...

Abstract: 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.

A mill’s heat balance evaluation was done using an Excel spreadsheet to evaluate the mill drying capacity constraint. Coal analysis was done on hard grove grind ability, abrasive indices and calorific value of coal. The effect of low calorific value coal was observed on mill’s response to match the boiler energy requirements.
