Types Of Boiler Coal Pulverizers Bright Hub Engineering

Jan 29, 2010 Thermal power plants use different types of coal pulverizers. The method used is attrition, impact, or a combination of both. This article explains the characteristics of the three main types- attrition, impact and attrition, and impact or hammer. Selection of the type of pulverizer depends on the grindability of the coal, the capital costs and maintenance costs, and considerations for licensing.

pulverizer differential pressure the difference in pressure at the pulverizer inlet and inside the pulverizer. When grinding cannot keep up with the supply rate of the woody mass, more and more non-pulverized and partially pulverized woody biomass circulates inside the pulverizer, and the pulverizer differential pressure continually rises.

Many coal pulverizer designs do not incorporate any filtration in their lube circuits. The pulverizers that do not incorporate filtration use coarse filtration such as 40-micron cleanable mesh or 200-micron cleanable, stacked disk filters. Such OEM-supplied filtration is often unable to keep up with the inherently high ingression rate.
