From the coal bin, the coal is fed into the coal pulverizer and dried using ~300° F air . When coal is pulverized, the process grinds the coal into a fine dust which expands the coal's surface area allowing the coal to ignite quicker and burn hotter and faster.
Pulverized Coal Pipe Testing and Balancing By Richard F. (Dick) Storm, PE The first step in optimizing combustion system performance is balancing the air and fuel flowing through each of the plant's coal pipes—the pipes that convey the air/fuel mix from the pulverizers to the individual burners …
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 injector in modern cars.
The raw coal is then fed into the pulverizer along with air heated to about 650 degrees 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.
