The coal combustion process produces many pollutants, and in turn leads to acid rain and climate change like global warming. Operating a boiler that is not optimized further leads to increased levels of unburnt carbon, increased excess air requirements, incorrect primary and secondary air to fuel ratios, reduced boiler efficiency and
Pulverized Coal Fired Steam Boilers 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.
2. Pulverised Fuel Firing: In pulverised fuel firing system the coal is reduced to a fine powder with the help of grinding mill and then projected into the combustion chamber with the help of hot air current. The amount of air required (known as secondary air) to complete the combustion is supplied separately to the combustion chamber.

Circulating Fluidized Bed (CFB) combustion boilers gives the flexibility for combustion of a wide range of coals and alternative fuel sources. All this without compromising efficiency and with reduced emissions. The key differences of the CFB boiler with the universally accepted Pulverised coal firing is discussed in this article.
Pulverised Coal an overview ScienceDirect Topics. Pulverized coal combustion includes wall-fired, tangentially fired, arch-fired, and roof-fired systems. Wall-fired and tangentially fired systems are the most common type of boilers. PC firing uses pulverizers to grind the fuel to particle sizes of typically 70% passing through 200 mesh or 74 μm .

10/3/2010· The combustion of coal in coal-fired power plants (see Chapter 4) produces several solid waste products referred to as coal-combustion products (CCPs), coal-combustion byproducts (CCBs), or pulverized fuel ash (PFA). Solid wastes include fly ash, bottom ash, boiler slag, flue-gas desulfurization (FGD), and fluidized bed combustion (FBC) wastes.
