Coal fired industrial boiler soot blowing system

Coal-fired boilers influence plants to release lignite rich in limestone that contains quicklime (CaO). It rapidly breaks down in water to form calcium hydroxide (Ca (OH)2) and is carried by rainwater to the water bodies from the slag dump zones. Lime-softening procedure accelerates Ca and Mg particles, which gives temporary hardness to the water and then forms NaHCO 3 and white soda.
