Pulverised Coal - an overview | ScienceDirect Topics

The raw coal is then fed into the pulverizer along with air heated to about 330°C (650°F) from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.

A Comparison of Three Types of Coal Pulverizers

Properly sized pulverized coal, however, passes into the fan section. In this section, an integral fan wheel, with abrasion-resistant alloy fan blades, transports the pulverized coal from the pulverizer section through the coal pipes to the burners. A typical arrangement of an ATRITA pulverizer system is shown in Figure 3.

Coal Pulverizer - Pall

Introduction. Power generation industry studies have shown that coal pulverizers are an area where improved equipment reliability is badly needed. The Electric Research Institute (EPRI) has determined that 1% of plant availability is lost on average due to pulverizerrelated problems.1 EPRI also identified oil contamination and excessive leakage as two areas where pulverizer drive train failures account for 53% of pulverizer problems.
