RPS - Model AA Series - FGD Slurry Spray Pipings
Coal-fired power plants produce boiler flue gases which must be scrubbed of chemicals and particulate before exiting through the stack. The internal and external lining in our FRP headers is virtually unaffected by the acid and high chloride environment inside an FGD tower that eats away at metallic piping. Small- and medium-sized FGD towers can utilized self supporting FRP header designs. In larger towers, even with supporting beams, FRP headers are still the most economical choice. Lightweight, easy to install, with options liked flanged or Victaulic ends, adhesively bonded joints or traditional butt joints, FRP offers design flexibility unmatched by metallic piping.
