Performance optimisation of vertical spindle coal pulverisers
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.
