The most common heat transfer method for coal-fired boilers is the watertube method in which the hot combustion gases contact the outside of the heat transfer tubes, while the boiler water and steam are contained within the tubes. Coal-fired watertube boilers include pulverized coal, cyclone, stoker, fluidized bed, and handfed units.

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.
regulation of the unit's coal mills. The demand for energy input to the boiler is set by the Boiler Master logic. The demand for BTU input is cross limited by total airflow. Total coal flow is calculated by summing the coal flow for each mill. The type of coal flow measurement varies from plant to plant, and may be derived from
