Particulate Control Technologies

• Electrostatic Precipitator (ESP)

An ESP is an efficient particulate removal device, with a low equipment pressure drop and high operation stability. It is suitable to dust removal with large flue gas flow rates, and is widely used in the flue gas treatment applications in coal-fired boilers and power plants, iron and steel industry, and metallurgical processes.

• Baghouse Dust Collector

The baghouse dust collector has the advantages of high particulate control efficiency, operational stability and ease of operation and maintenance. The efficiency of the baghouse is not affected by the dust properties or operating conditions, and it is widely used in iron and steel, smelting, chemicals, food, and power industries.

Equipment Utilization	> 98%

 

• Electrostatically Enhanced Baghouse

The electrostatically enhanced baghouse takes the advantages of the ESP and the baghouse and improves the adaptability and reliability of the baghouse filtration system. The electrostatically enhanced baghouse maintains a high particulate control efficiency when operating in conditions with large variations in coal type and boiler load.

• Wet Dust Scrubbing

The wet dust scrubbing system is an ideal solution for treating highly adhesive dust and can be operated under high temperature or high-humidity conditions, where the ESP and baghouse dust collectors cannot be effectively applied. Wet dust scrubbing is especially suitable for treating FCC flue gas in refineries. The wet dust scrubbing process is not affected by the specific electrical resistance of the dust particles and maintains a high particulate removal efficiency when operated in conditions with variations in coal type and boiler load.
