The combustion process of the pulverized coal in the boiler is a complicated nonlinear phenomenon. The pollutants emitted from thermal power plants depend largely upon the characteristics of the fuel burned, temperature of the furnace, actual air used, and any additional devices to control the emissions.
The historical development of coalfired power plants is listed in Figure 12. In 1884, Sir Charles Parsons built the first steam turbinegenerator with a thermal efficiency of only %. Two years later he improved the steam turbine performance by introducing the .
Pulverized Coal Fired Boiler Waterwall Corrosion PCFired Boilers generate thermal energy by burning pulverized coal that is blown by a combustion air stream to the burners in the firebox. These coal burners are typically located on the front and rear walls or in each of the corners to be known as wall fired or corner fired burners, respectively.

IEA Clean Coal Centre – Optimising fuel flow in pulverised coal and biomassfired boilers 10 1 Introduction Increasingly stringent environmental legislation and an obvious need to be economically viable mean that operators of coalfired power plants are constantly striving to improve overall plant performance (Rodriguez and others, ).
to coal leads to lower burner flame temperature, which In order to address these issues and develop innovative, costeffective and practical solutions, Air Products undertook and recently completed extensive analysis of oxygenenriched combustion of biomass in a 22 MWe US utility wallfired pulverized coal (PC) boiler. The analysis was
The pulverised coal obtained is transferred to the pulverised coal bunker (bin). The transporting air is separated from the coal in the cyclone separator. The primary air is mixed with the coal at the feeder and the mixture is supplied to the burner. Advantages l. The pulverising mill grinds the coal at a steady rate irrespective of boiler feed. 2.
