Oct 15, 2019 · The results show that the removal effect of ash is better than that of sulfur, which further proves that the compound dry separator can only remove inorganic sulfur from coal, but it can not remove organic sulfur from coal symbiotically. Therefore, the effect of ash removal is better than that of desulphurization. 3.2.

Another option is to "wash" the coal to remove some of the sulfur. The power plant can also install equipment called scrubbers, which remove the sulfur dioxide from gases leaving the smokestack. Because nitrogen oxides are created in the process of burning coal and other fossil fuels, some power plants are changing the way they burn coal.

A scrubber is used to remove sulfur dioxide (SO2) from the flue gas from a coal-fired power plant. The scrubber works by spraying high-pH water downward through a tower while the flue gas passes upward, transferring the SO2 from the gas to the water. The influent flue gas enters the tower at a rate of 50000 m 3 /h and contains 645 mg/m 3 of SO2 ...
