Limestone gypsum wet flue gas desulfurization system

The wet flue gas desulfurization system adopts the limestone/lime gypsum wet flue gas desulfurization (FGD) technology introduced from the German company LG (formerly LLB), which has the advantages of high desulfurization efficiency, strong reliability, comprehensive utilization of desulfurization by-products, and no secondary pollution. This technology is the preferred choice for flue gas desulfurization of large capacity power generation units, suitable for flue gas desulfurization projects in coal-fired power plants, coal-fired heating boilers, metallurgical sintering machines, and other enterprises. It is the primary choice for purifying boiler exhaust gas.

Main features:

High desulfurization efficiency, reaching over 95%;

The chemical dosage ratio of the absorbent is low, about 1.03;

Low liquid/gas ratio (L/G) can reduce the energy consumption of the desulfurization system;

High purity desulfurization by-product gypsum can be obtained, creating favorable conditions for the comprehensive utilization of desulfurization by-products;

The use of an empty tower design significantly reduces the inner diameter of the absorption tower and greatly reduces the internal components, thereby reducing the possibility of scaling;

Using inexpensive and readily available limestone/lime as absorbents can effectively control operating costs;

The system has high reliability, with an availability rate of over 98%;

Good adaptability to changes in coal quality of boiler coal, and can still maintain high desulfurization efficiency when the sulfur content of coal increases;

Good adaptability to changes in boiler load, the desulfurization system can still maintain high desulfurization efficiency and system stability under different flue gas loads and SO2 concentrations.
