5. Seal Fan: The air is from cold primary air, the seal fan sending to coal machinery and coal mill; as for the coal mill, the sealing air is used in grinding roller, roller bowl mill, spring loaded and other parts. 

New Design FD Fans for Boilers

6. Boost Fan: One part air enters into boost fan from ID Fan, the other part air enters into chimney by-pass. The by-pass is not allowed to open during the power unit working, otherwise, the smoke air without desulfurization environmental protection can not reach up to standard. 

Stainless Steel Material High Corrosive Fan

The air from boost fan will enter into gas desulfurization system, in the simulation of flue gas desulfurization and denitrification system of large-scale thermal power station, boost fan is the core of flue gas system.
