Raw coal feed pipe pulverizer. Coal is fed into a pulverizer where it is crushed and dried using hot air at from the pulverizer through the transport pipe and into the dust collector. Raw coal is fed into the coal inlet, dried and ground to a fine dust on the grinding table. [].Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner.

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.A brush seal assembly for a coal pulverizer includes multiple identical assembly segments. Each assembly segment comprises an arcuate brush assembly, a pair of clamping block assemblies and a pair of mounting bolts.
