COAL BASED THERMAL POWER PLANTS: COAL MILLS FOR THERMAL
Dec 13, 2011 · 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 twothirds of the ball mills.

Heat rate (efficiency) Wikipedia
Heat rate is a term commonly used in power stations to indie the power plant efficiency.The heat rate is the inverse of the efficiency: a lower heat rate is better. = The term efficiency is a dimensionless measure (sometimes quoted in percent), and strictly heat rate is dimensionless as well, but often written as energy per energy in relevant units.
