Coal pulverising mill. After pulverising, the coal is transferred by an air stream to the burners. This air is provided by the primary air fan associated with each mill. To permit the heat release from the fuel to follow the steam requirements of the generating sets, the raw coal is fed into the mills by rotary table feeders.

The pulverising (comminution) process is carried out on an on-demand basis by devices called pulverisers (or mills). The key element of the pulverised fuel system is the coal pulveriser (mill).The purpose of the pulverisers is the comminution (size reduction) of incoming coal from a typical top size of between 50 and 75 mm down to 75 microns (μm).

pulverized coal (fuel) carried by air in pipe-networks to feed the boiler furnaces of a power-station. The pipe-network considered consists of four 457mm-diameter mill pipes which take the pulverised coal of nominal size 75micron from a coal-pulverising mill, to a boiler furnace, with 2 pipes going to its front, and 2 to its back side.

In the modern pulverized coal power plant, pulverized fuel preparation totally depends on the grinding mill. Ventilation mills (VMs), which are continuous grinding machines and the most efficient structures in coal grinding technology, have become progressively larger and more efficient, . Fig. 1 shows the VM MB3600 with the following specifications: 490 r/min rotational …

PC firing uses pulverizers to grind the fuel to particle sizes of typically >70% passing through 200 mesh or 74 μm [33]. PC firing typically occurs at temperatures of 2500°F to 2900°F (1370–1590°C). Optimal fuel chemistry can be designed for PC firing through fuel blending, as is discussed in detail in subsequent chapters of this book.

Pulverizers / Mills. Reliable coal pulverizer performance is essential for sustained full-load operation of today's power plants. An effective pulverizer must be capable of handling a wide variety of coals and accommodating load swings in utility boilers as large as 1,300 MW. B&W's pulverizers, found at power stations throughout the world.

This presented a challenge when it came to pulverising it. Before fuel at the power station can be combusted, a set of mills pulverises it into a fine powder using a ring of rotating, heavy-duty balls. This fuel powder is then dried inside the mill with a mix of hot air drawn from the boiler house and cool air.

The basic input into the system is the fuel that is coal. All other systems and equipment only aid in this conversion process. Before going into the details, let us look at the quantity of coal processed in a power plant. A 2000 MW power station could be handling coal in the range of 1600 tons/hr or around 12 million tons of coal annually.
