At present, the desulfurization processes used in thermal power plants are mainly dry desulfurization and wet desulfurization, both of which require limestone powder to be used as desulfurization agent, so the pulverizer has also become an indispensable equipment in the desulfurization system.
According to the different requirements of dry desulfurization and wet desulfurization on the fineness of limestone powder, we can provide different grinding equipment configuration schemes. The absorbent used for dry flue gas desulfurization is calcium carbonate, calcium oxide or even calcium hydroxide, and the required fineness range is within 1mm. The SMMVIK Machinery vertical mill, overpressure trapezoidal mill, European mill and other equipment can meet the fineness requirements.
Wet limestone flue gas desulfurization process is widely used in coal-fired power plants today. The fineness of limestone powder as desulfurization absorbent shall be determined according to the characteristics of limestone and the comprehensive optimization of desulfurization system and limestone powder grinding system. For boilers burning medium and low sulfur fuel coal, the fineness of limestone powder shall be 250 meshes with 91% passing rate. When burning coal with high sulfur content, the fineness of limestone powder shall be 90% of the passing rate of 325 meshes.
SMMVIK Machinery has many years of experience in R&D and production, perfect pre-sale and after-sales services to ensure the normal and stable operation of the equipment, and can also configure appropriate production line equipment for users according to their needs and budgets. If you are interested in our equipment, you are welcome to consult, and we look forward to your arrival.
