Raw Coal Spillage Or "Pyriting"

Pulverizer throats that are not properly sized or have been enlarged by wear may result in serious coal dribble or spillage. Coal dribble or spillage is raw coal that is rejected through the pulverizer's 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 ...

 · While selecting a pulverizer, the coal characteristics play an important role. The Hardgrove index, total moisture, input coal size, output fineness, and mill wear have direct impact on the mill output. The Hardgrove index of coal tells us about the ease with which it can be pulverized. A higher Hardgrove index indies the coal is easier to grind. 50 HGI normally is taken for calculating the ...

Fire and Explosion Prevention in Coal Pulverizing Systems

Fire and Explosion Prevention in Coal Pulverizing Systems

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. RECENT INDUSTRY TRENDS Industry trends which could increase the probability of fires ...
