To efficiently combust coal, it needs to be pulverized into fine particles (100μm) before being placed in a boiler. A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classification functions.

Presentation Transcript. Fuel oil System • Purpose: (a) to establish initial boiler light up. (b) to support the furnace flame during low load operation. • Fuel oil system Consists of • Fuel oil Pumps • Oil heaters • Filters • Steam tracing lines Objective is to get filtered oil at correct pressure and temperature.
Pulverized coal injection (PCI) is a process which involves injecting large volumes of fine coal particles into the raceway of the blast furnace (BF). Pulverized coal is an important auxiliary fuel used in the BF ironmaking. PCI provides auxiliary fuel for partial coke replacement and has proven both economically and environmentally favourable.

7.2.3.1 General. Pulverised coal (PC) combustion is the most widely used technology for utility-scale power generation in the world. In PC boilers, coal is ground into fine particles (∼100 μm) and then injected with heated combustion air through a number of burners into the lower part of the furnace.
Therefore, one of the major requirement of a power plant is to reduce the cost of handling of coal from the point of its origin upto the furnace of boiler where it is burnt. Various steps involved in a coal handling system as shown in Figure A are : Coal delivery. Unloading. Preparation of coal. Transfer of coal. Storage.
