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.

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.

Coal preparation, which involves feeding, drying, and grinding of the coal, and the pneumatic transport of the pulverized coal to the burners, is fully integrated with the boiler. For lower reactivity coals, the fineness of grind is increased to create a larger specific surface area so as to improve conditions for ignition and combustion.
Pulverizedcoal firing is especially suitable for very large boilers and cement kilns. A wide range of coals can be burnt, but coal preparation and gas cleaning are major cost items. 70% lt; 75 m is required for bituminous coals, 80% for anthracite. Coal dried with air at 250350#176;C for milling in low, medium or highspeed mills.

The promise of coal gasification has even won, at the very least, the interest of some environmental groups that have long opposed the continued use of pulverized coal plants, even though upgrades and the adaptation of such practices as Ultra Supercritical Coal technology, which increases efficiency by roughly 10 percent, have made those plants cleaner.

By rapid pyrolysis of pulverized coal in oxygen and steam atmosphere, powder activated coke (PAC) nanostructured carbon material was derived by one step. Then, nitrogen adsorption measurement, scanning electric measurement (SEM) and Fourier transform infrared spectroscopy (FTIR) test were conducted to analyse the detail characteristic of the obtained PACs.
