Power Plant Desulfurization

Guidance

Limestone/ gypsum dry process/ semi dry process/ wet process desulphurization is a process to desulfurize flue gas. It has the advantages of mature technology, low investment, high efficiency, low operating cost, and is suitable for large capacity units. It is the most widely used desulfurization process in the world.

WER takes “practical, innovative, environmental protection, low energy consumption” as the concept of industrial equipment manufacturing. With more than 30-year experience, WER is committed to providing power plant and its cooperative enterprises with integrated desulfurizer project solutions and product customization services. At present, WER has designed and established dozens of advanced wet desulfurization process production lines for large power plants such as China Guodian Corporation, China Huadian Corporation, State Power Investment, CHINA HUANENG, China Resources (Holdings) Corporation and Northern United Power, covering important large power plants in East China, North China and Northwest China, etc.

Limestone is crushed, grinded and slurried and then transported to the absorption tower. The slurry in the absorber is sent to the spraying device by circulating pump for spraying.

Powder Requirements

Raw material: limestone, quick lime (CaO), Gypsum

Powder fineness: 250 mesh, d90; 350 mesh, d90

In order to ensure the comprehensive utilization of desulfurization gypsum and reduce wastewater discharge, the content of CaCO3 in limestone used for desulfurization should be higher than 90%. The fineness of limestone powder should guarantee 90% screening rate of 250mesh for boilers burning medium and low sulphur fuel coal, and 90% screening rate of 325mesh for boilers burning medium and high sulphur content coal. Quicklime can also be used as absorbent. The purity of quicklime should be higher than 85%.


Grinding Equipment

    The PC Hammer Mill, MTW, MTM Medium Speed Trapezium Mill, Ball Mill and the LM, LUM Vertical Mill cover all requirements of crude, fine and ultrafine powder production in the industrial milling field. Production of free combination from 0 to 2500 meshes can be realized. No matter which industry you are in, chemistry, energy, construction material or metallurgy field, SBM will always meet all your demands.
