Coal fired boiler is widely used to generate thermal energy by burning fuel in the firebox. Coal can provide lower operating costs in comparison to other fossil fuels like oil or natural gas, it is one of the cleanest fossil fuels available today due to the state of the art computerized pulverized coal handling and combustion technology.

Dust particles in the inlet gas are collected on the filters by inertial impaction, diffusion, direct interception, and sieving. The collection efficiencies of fabric filters or coal-fired boilers can exceed 99 percent.
Read MoreMany coal-fired boilers have been converted to burn cleaner fuels such as natural gas and oil. But escalating fuel costs are causing many plants to re-examine the use of coal as a primary boiler fuel. However, before reconverting to coal, owners must evaluate pertinent environmental regulations and emission control strategies.

Read MoreJun 15, 1994 · Unit One is a pulverized coal-fired, dry bottom boiler with an opposed firing configuration. Low NOx burners are used to control NOx emissions. Normal operating temperature in the combustion zone is approximately 2,000 - 3,000 degF. The boiler produces 4,500,000 lb/hr of steam for a General Electric steam turbine generator rated at 688 MWe.
Read MoreFor coal-fired power plants, the HAPs of most concern are metals such as mercury, arsenic, and vanadium. All combustion processes produce particulate matter. Amounts and size distribution of the particulates emitted depend on a number of factors, including fuel burned, type of boiler, and effectiveness of collection devices.
