To summarize the coal mill controls, they may be divided basically into two major egories:. 1. To control the quality of coal being sent to the burners loed on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.

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.

ATOX coal mill. Working principles The raw coal enters the mill via a rotary sluice and feed chute and is discharged onto the rotating grinding table. The rotation of the table accelerates the flow of material towards the grinding track, where the coal is ground between the table and the three rollers. The coal then continues over the dam
The ELtype pulverizer is a higher capacity pulverizer when compared to the original Etype pulverizer of the same size. E to EL conversions have significantly improved the availability, capacity, and reliability of Etype pulverizers. The ELtype pulverizer is also much less prone to coal dribble problems due to an improved bottom grinding

While renewable energy has undergone wide and rapid deployment, coal is still expected to be the main source of fuel for producing base load power in the near future. This is because coal reserves are expected to last for the next century and its cost is still relatively cheap. However, the emissions from coal combustion are a major environmental concern.
