Gas Turbine Guillotine Dampers
Our design of Gas Turbine Guillotine Damper is the industry’s preferred choice for high-temperature GT service. Through its installed downstream of a Gas Flow Diverter, the GT Guillotine Damper provides 100% isolation to enable ‘man-safe’ entry.
Self-cleaning drives never need lubrication and are highly rugged and reliable. An electric actuator and gearbox give positive drive to the blade in both directions, eliminating the possibility of stretching or mechanical binding occuring in chain-drive mechanisms. Both vertical, side or flat draw orientations are possible.
|The blade is a corrugated construction, fully supported from deflection on all sides by the solid seat. The ‘C’ shaped blade profile channel perimeter enables full thermal expansions in all four directions eliminating the possibility of distortion occuring in conventional solid plate designs.|
|The design provides for a labyrinth path for flue gas through a two-sided contacting arrangement. Super-alloy seal materials retain their ‘spring-back’ properties at elevated temperatures. A minimum of 99.9% sealing efficiency is guaranteed and a 100% with seal-air.|
