Desulphurization pumps are specially designed pumps used in the coal-fired power generation industry to pump flue gas desulfurization (FGD) slurry. FGD slurry is a mixture of limestone and water that is used to remove sulfur dioxide (SO2) from the flue gas produced by coal-fired power plants.

The desulphurization pumps are designed to handle the abrasive and corrosive nature of the FGD slurry, which can cause significant wear and tear on the pump components. The pump casing, impeller, and wear rings are typically made of materials that are resistant to abrasion and corrosion, such as high-chrome white iron, rubber, or ceramic.

Desulphurization pumps may be either centrifugal or positive displacement pumps. Centrifugal pumps are commonly used for FGD applications, as they are able to handle high flow rates and low to moderate pressures. Positive displacement pumps, such as diaphragm pumps or peristaltic pumps, may be used for lower flow rates or when a more precise flow control is required.

Regular maintenance and monitoring of desulphurization pumps are essential to ensure their proper operation and prevent downtime. This includes monitoring the pump performance, checking for leaks and wear, and performing regular maintenance tasks such as cleaning, lubrication, and replacement of worn or damaged components.

In summary, desulphurization pumps are specialized pumps designed to handle the abrasive and corrosive nature of FGD slurry in coal-fired power plants. These pumps play a critical role in the power generation process by ensuring the effective removal of SO2 from flue gas, which helps to reduce air pollution and protect the environment.
