01/06/2017 · The pollutants in flue gas from coal-fired power plant include SO 2, NO x, CO 2, SO 3, HCl and other acid gas which can react with water vapor. Also there are substances that cannot be absorbed by water, such as smoke particles, CO, polycyclic aromatic hydrocarbons (PAH) and other hydrocarbons, as well as trace heavy metal elements(Hg, As, Pb).

30/10/2019 · Sulfur in the flue gasses reacts with the limestone to form gypsum that, when separated from the fly ash, can be used to make other saleable products. Post-Combustion. Coal ash leaving the combustion chamber can be captured and particulate pollutants

Firing with minimal excess air decreases stack gas heat loss by reducing flue gas flow and lowering gas velocity through the boiler. As a result boiler tube surfaces are in contact with the hot flue gases longer (increased residence time) and heat can be more thoroughly absorbed. The longer resi- dence time also promotes complete combustion.
