how to choose the model of coal mill

Coal Mill

Coal is pulverized in the coal mill to a very fine particle size. The coal and primary air are then introduced to the coal nozzle. Swirled air, coupled with the burner throat’s flow-shaping contour, enables recirculation patterns that extend into the furnace.

modelling of vertical spindle mills in coal fired power plants

A mathematical model of a vertical spindle mill used in coal-fired power plant is presented. The model is developed based on a mill size mass balance (SMB) and mill global mass and energy balances. The model has been validated using data collected from a 660 MW unit during mill modelling field tests.
