BHEL specifications for FGD pumps in Bangladesh project

There are 2 units of each 660 MW and each unit is envisaged with one FGD system. Each FGD system will be provided with 5 numbers of Recirculation pump (4 working + 1 standby) which are located inside the Recirculation Pump & Oxidation Blower House. The specificiations for the FGD recirculating pump allow for rubber lining, stainless alloys or silicon carbide materials in contact with the sulfite slurry with a maximum of 27,000 ppm chlorides.

Specification for High Temperature and Acid Resistant Terpolymer Fluoroelastomer

Fluid Sealing Association Standard FSA-DSJ-401-07: This specification provides requirements for the terpolymer fluorocarbon elastomer used in the manufacture of expansion joints for application in coal fired utility and other high temperature industrial applications where corrosive flue gases are present. Four products known to meet 4.1 are Dai-elTM brand terpolymer fluoroelastomer bisphenol-cured , DyneonTM terpolymer fluoroelastomer incorporated cure products, TecnoflonTM brand terpolymer fluoroelastomer incorporated cure products and Viton™ brand fluoroelastomer (B type) products bisphenol-cured. Other equivalent fluoroelastomer terpolymers of at least 68% by weight fluorine content with equivalent curatives are acceptable.
