Boilers machinery : Coal Pulverizer

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.

Coil Pulverizers for Boilers Bright Hub Engineering

Pulverized coal is the most efficient way of using coal in a steam generator. The coal is ground so that about 70 % will pass through 200 mesh (0.075 mm) and 99 % will pass through 50 mesh (0.300 mm). A pulverized coal boiler can be easily adapted for other fuels like gas if required later without much difficulty.

Types of pulverised coal firing system BrainKart

Crushed coal from the coal bunker is fed by gravity to a dryer where hot air is passed through the coal to dry it. The dryer may use waste flue gasses, preheated air or bleeder steam as drying agent. The dry coal is then transferred to the pulverising mill. The pulverised coal obtained is transferred to the pulverised coal bunker (bin).

A Comparison of Three Types of Coal Pulverizers

Properly sized pulverized coal, however, passes into the fan section. In this section, an integral fan wheel, with abrasion-resistant alloy fan blades, transports the pulverized coal from the pulverizer section through the coal pipes to the burners. A typical arrangement of an ATRITA pulverizer system is shown in Figure 3.

Pulverized Coal Fired Steam Boilers Reliable Steam

A pulverized coal fired 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 pulverized fuel is to use the whole volume of the furnace for the combustion of solid fuels.
