Background
The coal is combustible coal, which is called coal. Coal is a solid combustible mineral formed gradually by ancient plants buried underground and undergoing complex biochemical and physicochemical changes. Coal combustion not only produces a large amount of smoke dust, but also produces harmful gases such as carbon monoxide, sulfur dioxide and the like. Organic matters, sulfate, black carbon and other substances directly related to coal emission are main components of PM2.5, and coal pollution is a primary source for causing large-range air heavy pollution. The basic principle of flue gas desulfurization is acid-base neutralization reaction. The sulfur dioxide in the coal combustion flue gas is an acidic substance and reacts with an alkaline substance to generate sulfite or sulfate, so that the sulfur dioxide in the flue gas is removed. The most commonly used alkaline substances are limestone, quicklime and slaked lime, but also ammonia and other alkaline substances such as seawater can be used.
