[0002] As the name implies, a desulfurized coal-fired boiler is a device that integrates a desulfurization function into a coal-fired boiler. The principle is mainly to add desulfurizers (such as lime, gypsum, etc.) during the coal combustion process. These desulfurizers can react chemically with sulfur dioxide released from the coal, converting it into solid substances such as gypsum and sulfuric acid, and finally discharge or recycle it through the treatment system. In this way, the sulfur dioxide content in the flue gas is effectively reduced, achieving the purpose of protecting the environment.
