White Smoke Elimination

It is common to adopt wet limestone desulfurization and denitrification process in iron and steel industry, coal burning power plant, chemical industry and other relative industries. The flue gas after desulfurization and denitrification carries a large amount of water vapor. If it discharges directly by the chimney, not only causing a waste of water, but also resulting the ‘white smoke plume’, which is a visual air pollution and will lead to the hazy weather. The white smoke elimination is a way to remove the white smoke plume by cooling off and extracting the water from the flue gas and collecting the heat to reuse, so that the exhaust gas will meet the environmental standard of emission.

Booster Fan

The condensation and reheat technology is one of the most widely used technology for white smoke elimination. The content of the water vapor in the flue gas is reduced by cooling off the flue gas, and then the temperature of the flue gas is rising after heat exchange device, so as to achieve the purpose of white smoke elimination. The booster fan always used with the heat exchange device. Centrifugal fan is very common type; axial fan can also be used.
