Biomass Utilisation for Power Generation through Co-firing in Coal Based. Power Plants. 1. Introduction. Stubble burning has been cited as a major cause of recent mills/vertical roller mills/beater mills. However, this method is not suitable for power plant having ball and tube type of mills due to higher risk of fire hazard.

ABSTRACT. The coal mill used in the coal-fired power plants is modeled in view of the controller design rather than the eduional simulator. on the rotating table and it is ground under the roller. The primary air is generated by mixing hot and cold air, and it is introduced through an opening near the base of the coal mill.
