COAL PULVERIZING SYSTEM . Figure 1 shows a typical mill system schematic including fuel bunker, feeder, mill, primary air system and relevant dampers. Raw coal is fed from the feeder at a controlled feed rate, to meet boiler steam demand. In the meantime, hot primary air of 300°F to 700°F, depending on coal moisture content, is
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.
Depending on speed pulverizers are classified as lowspeed, mediumspeed, and highspeed mills. Pulverized coal burners may be located on the front or opposed walls or in the corners of the furnace. There are two types of fuelfiring systems: bin system and directfiring system. Coal feeders are either the volumetric or gravimetric type.

2. Central or Bin System: The crushed coal is fed to the drier from the raw coal bunker by gravity. The drying of coal is effected either by using hot gases, preheated air or bled steam. The dried coal is fed to the pulverizer with the help of feeder. The pulverized coal is carried from the pulverizer mill with the help of air and it is ...
A pulverized coalfired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
