sized pulverizer throat will require more than optimum primary air-flow to minimize coal rejects. The pulverizer "free annular jet" of vertically flowing airflow, in our experience, must be adjusted for a minimum of 7,000 fpm under normal operation. Throats that are oversized will result in either excessive coal rejects (not tramp metal

Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will be ground to a more uniformly fine size and dried to a greater extent. All these factors make the coal/ air mix- ture easier to ignite and, once ignited, more likely to detonate and cause an explosion. ...

pulverizer capacity. Capacity of a pulverizer is a minimum of five factors and these five factors are: tons throughput at a given fineness, at a given Hardgrove grindability index (HGI), at a given raw coal sizing entering the mill and at a given coal moisture content. Throughput alone is NOT a definition of pulverizer capacity! Please read on

Introduction. The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a pre-determined size in order to increase the surface area of the coal.. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.
