Mill maintenance costs are one of the highest maintenance costs in a coal fired power station; Testing allows a change to 'condition based' maintenance (from set mill operating hours) which in HRL's experience can increase time between minor / major mill overhauls by up to 10%;

4. Lower air flow results in better fineness & less erosion. 5. Lower air flow can result in more pyrites, but fewer burner eyebrows. 6. Lower air flow means and a greater tendency to plug with wet coal. 7. Lower air flow leaves more reserve fines in the pulverizer. 8. Also note that lower air flow leaves a deeper bed depth of coal, and thus a ...

Once normal coal flow is applied to the mill, a full mill test should be conducted. This should include isokinetic coal sampling and dirty airflow measurements through each fuel line to determine air fuel balance and coal fineness. Primary airflow "Hot-K" calibrations of the primary airflow measuring element should also be conducted.

A method for choosing the optimum fineness of coal in pulverised-fuel boilers is presented. This method is based on economic criteria and takes into account variations of the power unit load as well as the durability and the output of pulverisers. Calculations are performed for short periods of time (e.g. 1 h), provided that it is possible to ...

Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...
