Coal Pulverizer

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 40micron cleanable mesh or 200micron cleanable, stacked disk filters. Such OEMsupplied filtration is often unable to keep up with the inherently high ingression rate. This results in contamination levels often exceeding ISO ...

Coal Pulverizer

Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) before placing into a boiler, to ensure efficient combustion. Pulverizers have three functions, pulverization, drying and classifiion. The classifiion function plays the important role of ensuring that only fine particles of the pulverized coal ...

Reducing wear particulates in a coal pulverizer gearbox

Reducing wear particulates in a coal pulverizer gearbox

This particular plant had 13 of these coal pulverizers installed. After 10 years of operation, the bronze bull gear was rotated to expose the unworn gear teeth face side. This required four weeks of turnaround time, including maintenance work, at a total cost of 300,000 per unit. Every 20 years of operation, a complete rebuilding of the gearbox was required. Parts and labor for this effort ...

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 ...
