Cyclone Separator for Power Plant Flue Gas from China

A high-efficiency cyclone separator uses centrifugal force to remove ash and coarse particles from coal-fired power plant flue gases before further treatment. It is categorized under HTS 8421.39.0130 for other industrial gas cleaning equipment in utility applications. Multiple cyclones often operate in parallel for large-scale gas volumes.

Import Tips

Specify inlet/outlet gas velocities and particle size efficiency curves in import documentation

Ensure high-temperature alloy construction details for boiler flue compatibility

Avoid misdeclaration as simple ductwork by highlighting separation mechanism
