Flue Gas Desulphurization & Denitration

Flue Gas Desulphurization & Denitration

Solutions / F. G. D. & D.

Flue gas desulphurization & denitrification is applied in the purification process of the exhaust gases generated by nitrogen oxides and sulfur oxides. The exhaust gas produced by industrial boilers, steel, cement, chemical and other industries should go through the desulfurization & denitration and dust removal device to discharge, so that the sulfur dioxide and nitrogen oxide can be dealt with well. The fan is always used with desulfurization & denitration device, mainly including induced draft fan, aeration blower fan and dilution fan.

Induced Draft Fan

In the wet desulphurization process, the flue gas containing sulfur is going to the spray desulphurization tower by the induced draft fan directly or after dust removal by the dust collector.


Aeration Blower Fan

In the method of limestone or magnesium oxide desulfurization process, aeration blower fan is used to provide a large amount of compressed air into the bottom of the desulfurization tower, which can help for the reaction between air and limestone or magnesium oxide.

Dilution Fan

In the SCR denitration process, the role of dilution fan is blowing a large amount of air to dilute the ammonia gas to a certain proportion and then push it into the reactor pipeline.


Successful Cases

London fan products are high quality, good performance, high efficiency and strong stability, which are widely used in many industries. On the flue gas desulphurization & denitrification project, our company actively participates in SIEMAG Wuhan project, Shougang Research Institute of technology project, SINOPEC Luoyang project, Shanxi Guangda coking project, etc. Our fans perform well in each project, which makes us acclaimed by our customers.
