1. Pulverized coal is the most efficient way to burn coal for steam generation as it burns like gas and is easily ignited and controlled. 2. Pulverizers receive raw coal and pulverize it through processes of drying, grinding, circulation, and classification. Grinding occurs through impact, crushing, and attrition. Circulation air removes heavy particles and classification separates oversized particles. 3. Performance is measured by fineness, grindability, rejects, and capacity. Fineness indicates quality and is measured by particle size distribution. Grindability depends on coal properties like hardness. Rejects indicate foreign materials. Capacity depends on grinding mechanism and conditions.
