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.

Scrubber - Wikipedia

Wet scrubbers can also be used for heat recovery from hot gases by flue-gas condensation. In this mode, termed a condensing scrubber, water from the scrubber drain is circulated through a cooler to the nozzles at the top of the scrubber. The hot gas enters the scrubber at the bottom.

Flue-gas desulfurization - Wikipedia

Flue gas desulfurization scrubbers have been applied to combustion units firing coal and oil that range in size from 5 MW to 1500 MW. Scottish Power are spending £400 million installing FGD at Longannet power station, which has a capacity of over 2 GW. Dry scrubbers and spray scrubbers have generally been applied to units smaller than 300 MW.
