COAL FIRED BOILER -PRINCIPALS - Energy Commission
For a typical coal-fired power station, flue-gas desulfurization (FGD) may remove 90 percent or more of the SO 2 in the flue gases. History. Methods of removing sulfur dioxide from boiler and furnace exhaust gases have been studied for over 150 years. Early ideas for flue gas desulfurization were established in England around 1850.

Conventional PF coal-fired boilers, currently being used in the power industry, use air for combustion in which the nitrogen from the air (approximately 79% vol) dilutes combustion products such as CO 2 and water vapor in the flue gas. During oxyfuel combustion, a combination of oxygen (typically of greater than 95% purity) and recycled flue gas is used for combustion of the fuel.
the flue gas. These factors mean that some form of flue gas treatment may be required. Flue gas treatment for CO 2 capture 5 The major impurities in the CO 2flue gas stream are water vapour, nitrogen, oxygen and argon. SO 2, NO 2, HCl and HF are minor impurities. Mercury is present in trace amounts. Moisture has to be removed to avoid corrosion and hydrate
Coal Fired Boiler Emissions Test - EPA. Entropy tested the exhaust gases from the Unit 1 coal-fired boiler. The furnace burns bituminous coal. Gases from the combustion furnace pass through two electrostatic precipitators (ESPs) to control particulate. exiting the ESPs pass through a desulfurization unit (FGD) to remove SO2 and are then exhausted through a stack.
