Pulverised Coal - an overview ScienceDirect Topics

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. The burner mixes the powdered coal in the air suspension with additional preheated combustion air and forces it out of a nozzle, similar in action to fuel being atomized by a fuel ...

Improving Coal Pulverizer Performance and Reliability

Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported by an air or an air/gas mixture, pulverized coal can be introduced directly into the boiler for combustion. There are several pieces of equipment involved in processing coal to be burned in this fashion. Figure 1 is a simplified diagram detailing this ...
