Coal mill pulverizer in thermal power plants

Coal mill pulverizer in thermal power plants

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 330C 650F 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
