Importance Of Coal Pulveriser In Power Plant

2009-9-1 In coal-fired power plant, pulveriser is the first major component, whose performance dictates the total power plant efficiency. Uniform flow rate and desired size fraction at outlet pipes along with higher classifier efficiency are three important measures which decide the pulverizer performance.

A Comparison Of Three Types Of Coal Pulverizers

pacted on a grid section by swing hammers, reducing the coal to a nominal 1/4 size. Drying of the coal also occurs in this section. After the coal passes through the grid section, it enters the two-stage pulverizing sec- tion. This section further reduces the coal size by attrition and by impact of coal on the moving and stationary parts.

Raw Coal Spillage Or Pyriting

Coal dribble or spillage is raw coal that is rejected through the pulverizers pyrite discharge. This is caused when the velocity across the pulverizer throat is too low to maintain suspension of coal. Air velocities through the pulverizer throat should be 7,000 to 7,500 Fpm when calculated on a free jet basis.
