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. Gases exiting the ESPs pass through a flue gas desulfurization unit (FGD), to remove SO2, and are then exhausted through a stack.

An SO 2 scrubber system is the informal name for flue gas desulfurization (FGD) technology, which removes, or "scrubs," SO 2 emissions from the exhaust of coal-fired power plants. A scrubber works by spraying a wet slurry of limestone into a large chamber where the calcium in the limestone reacts with the SO 2 in the flue gas.

Power and Cogeneration Water and Wastewater Treatment Solutions

This is to be expected since the gasifier is “burning” coal or some other fuel source and releasing the same types of contaminants produced in a coal-fired boiler. The scrubber’s downstream flow must therefore be treated to remove heavy metals such as selenium, cadmium, and mercury, as well as other process contaminants.

Scrubbers - Global Energy Monitor

Rather than trying to remove sulfur from coal before it was burned by washing it, which had little effect, scrubbers aimed at the “back end” of a power plant, trying to remove sulfur in the form of sulfur dioxide (or SO2) from the flue gas exiting a coal boiler.

Solids accumulate because of evaporative processes, and in order to control the solids buildup, one has to waste high solids water and replace it with lower solids water. That is blowdown. The same thing is true in a scrubber, only the solids buildup tend to be particulate if it is operating on flue gasses, and salts if it is operating on a

Environmental Assessment of A Coal-Fired Controlled Utility

The composition of trace elements found in bottom and fly ash is similar. Based on tests of the coal-fired boiler, the rate of generation of solid waste from a 874 MW coal-fired boiler would be 0.11 Gg/hr of bottom slag/fly ash and 0.13 Gg/hr of scrubber sludge from the FGD operator.

Coal plants without scrubbers account for a majority of U.S

SO 2 is formed during the combustion of coal. The amount of SO 2 produced depends on the sulfur content of the coal burned in a boiler. FGD scrubbers remove the SO 2 from a boiler's post-combustion exhaust (flue gas) by passing it through an alkaline solution. This process is also effective in removing acid gases, such as hydrochloric acid.
