CHEMICAL GRADE LIMESTONE Flue Gas Treatment Carmeuse

Chemical grade limestone plays a critical role of keeping coal-fired boilers in environmental compliance. It is used in wet flue gas desulphurization (FGD) to reduce sulfur dioxide and other acid gases. This product is also injected into the boiler for additional reduction of acid gases and heavy metals. Additionally, limestone can be added to the coal belt to reduce arsenic and other heavy
