Coal pulverizers are the heart of a pulverized coal-fueled boiler. Often, the root causes of nonoptimized combustion lie with the pulverizers. . and fuel flow brought back to mill design fuel .
These systems utilize a pulverizer or mill to grind coal to a desired fineness and .. boiler designs were very conservative and based on single stage combustion.
A vertical spindle mill is also designed for pressurized and suction type requirements. Boiler designers use this type of mill for poor quality coal as this type of mill rejects foreign materials like stones and other high density materials. The power consumed by the mill per ton of coal ground is only two-thirds of the ball mills.
