To comply with these laws, coal fired power plants are incorporating flue gas desulfurization (FGD) scrubbing processes to remove sulfur dioxide from flue gas. Several different scrubber options are available for coal-fired power plants. In the United States the most popular system is the calcium (limestone)-based wet scrubber (Kalyoncu, 1999).

flue gas. In dry flue gas desulfurization (DFGD) technologies, the sorbent can be injected in a variety of possible locations within the power plant as an atomized slurry (lime spray drying, duct spray drying) or dry powder (furnace sorbent injection, duct sorbent injection). After sufficient contacting time, the sulfur-

The desulfurization effect of limestone grinding machine is remarkable after grinding limestone into powder. The power plant needs about 200-300 tons per day, and more than 130 grinders are selected for grinding equipment. Calcium oxide is used for desulfurization in furnace and calcium carbonate is used for flue gas desulfurization.

CHD Zhouxian Power Plant is a modern oversize pithead power plant and is an exclusively invested enterprise of Huadian power international co., LTD. In 2005, the company cooperated with our company and purchased one YGM130 type high pressure medium speed grinder from our company which is used for desulphurization limestone powder grinding test.

Semi-dry flue gas desulfurization (FGD) technology is used by some coal-based power plants to remove sulfur dioxide from flue gas. In semi-dry FGD systems, SO 2 is removed by calcium-based sorbents in a reactive spray dryer, but the level of desulfurization is lower than in wet FGD systems. This work evaluates the effects of seven additives in the desulfurization of the flue gas: …

The sulfur dioxide absorbed by the desulfurization absorbent reacts with the calcium carbonate and oxygen in the slurry, and finally generates gypsum.In this way, the sulfur dioxide in the exhaust gas from the power plant is removed, effectively avoiding environmental pollution, and the gypsum produced can be used in industrial production ...
