To grind coal to fine powder for further firing at the huge huge burners fitted in the water walls of boilers in the coal fired thermal power plants mainly to heat water and convert to high pressure, high temperature steam, steam to be fed in turb
Why coal mill are used in powerplantPozemnihokejcb. Why is a bowl coal mill used in a thermal power plant Quora. Bowl mills are one type of grinding mill used in a coalfired thermal power plant. Raw coal fed into the mills gets converted into pulverised coal and carried to the burners by primary air.
Types of coal pulverizers. Coal pulverizers may be classified by speed, as follows Low Speed Medium Speed High Speed Low speed Ball and tube mills. A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods.
Ball tube mills are either pressurized or suction type. In the pressurized type, the hot primary air is used for drying the coal and to transport the milled coal to the furnace. In this type, leakage in the mill area is the suction type, the exhauster is used for lifting the milled coal from the pulverizer to the furnace through a cyclone.
Summary. The Ball Mill is designed to grind materials by turning the cylindrical shell with grinding medium e.g. steel balls, cylpeb, and pebbles put in the shell, and has a simple structure and ease of handling.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand e.g., via a hand crank, working animal e.g., horse mill, wind or water .
Grinding. The grinding function reduces coal fed into the mill into a dust with particles of the size required for combustion. There are two main types of mill in common use the spindle type and the drum type. A typical spindle mill is shown in Fig. 5.
