Since the first application using an MPS mill to process pulverized coal in Germany in the mid 1960s, there have been over 2,000 different MPS mill installations operating in coal-fired power plants worldwide. As one of the most popular coal pulverizers in the utility industry, the MPS mill was first introduced into the US in the early 1970s.

The coal contains approximately 40 percent moisture and 12 percent ash. At full load, each unit fires approximately 900,000 lb/h of coal. The boilers are controlled circulation, radiant, single reheat, tangentially fired, balanced draft with divided furnace. Each boiler is equipped with eight mills feeding eight elevations of tilting fuel nozzles,

Low grade coal accounts for half of all coal resources in the world, and super-high-moisture coal with a moisture content exceeding 50% is one such kind. When such super-high-moisture coal is applied to conventional USC boilers, the shortage of mill drying capacity and the decline of

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

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.

Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) before placing into a boiler, to ensure efficient combustion. Pulverizers have three functions, pulverization, drying and classification. The classification function plays the important role of ensuring that only fine particles of the pulverized coal ...
