CFD modeling of MPS coal mill with moisture evaporation

Cfd Modeling Of Mps Coal Mill With Moisture Evaporation

May 01, 2010 Fig. 2 shows the pathlines of the flow inside the mill colored by velocity magnitude. Due to the tilted vanes of the throat, air flow leaving the throat has a helical pattern. This increases the residence time of the coal particles inside the mill and also enhances the primary separation of the coal particles by imparting a spin to them.

a fire. If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the air. Even when a mill is shut down routinely, there is a danger that any residual coal left within the mill will oxidise, which can explode as the mill is restarted. To prevent a coal fire, the mills
