Dilution fan

Dilution fans are widely used in power plant dilution fans for desulfurization and denitrification, also known as denitrification fans or desulfurization fans. Due to the stable performance, reliable quality, beautiful appearance, and reasonable design of the dilution fans produced by our factory, they are widely used for denitrification and environmental protection in major power plants across the country. They have been long-term matched with Jiangsu Baina, Jiangsu First Ring Road, Jiangsu Huanfa, Beijing Green Leaf, and the School of Thermal Power at Shandong University. Welcome customers to make purchases.

Dilution fan refers to a fan that provides air for the denitrification system of a power plant to dilute ammonia gas.

（1） Purpose:

Mainly used for100mw-600mwDilute the flue gas denitration reducing agent ammonia from the power station to allow ammonia from the ammonia buffer tank to pass through ammonia/After dilution and mixing with an air mixer, the concentration of ammonia gas is diluted.

（2） Model:

According to the required parameters such as air volume and pressure for the design, the main selected fan model is a high-pressure centrifugal fan.

（3） Characteristics:

It has the advantages of good aerodynamics, high efficiency, smooth operation, and simple maintenance

The function of dilution fan
The function of the dilution fan is to dilute ammonia to a certain proportion and spray it into the reactor flue to prevent ammonia from mixing with air to reach an explosive ratio, thereby causing danger. Each unit is equipped with two dilution fans, one in operation and one backup.

Trial operation and interlock protection of dilution fan
Generally, the dilution fan is designed for one operation and one backup or two operations and one backup, and a chain protection test is conducted. The dilution fan is put into operation during the boiler ignition period.

Selection of dilution fan
Dilution fans are generally selected with high pressureofHigh pressure fan, ensure that the ammonia air dilution ratio is not greater than5%.

Application of dilution fan in China's well-known desulfurization and desulfurization industry
Dilution fans are widely used in well-known desulfurization and desulfurization environmental protection enterprises in China, with mature applicable models and a large number of usage achievements. They are widely used every year in Fujian Longjing desulfurization and desulfurization environmental protection company and Wuhan Kaidi electric power environmental protection company.
