Damper

Through aggressive technology development investment and design, NES contributes to customer needs and product production, which has led to a lot of results in Boiler, HRSG and FGD projects.

Boiler & HRSG Damper

Boiler Damper must be designed with high temperatures in mind. Installation of Insulation & Liner or Castable construction is also required. To prevent heat deformation, Thermal Expansion and Blade Deposition should be considered first. We have high technical skills in designing the Boiler Damper.

FGD Damper

The Damper in desulfurizing facility consists of an inlet damper, an outlet damper and an emergency bypass damper. Due to gases containing sulphur, all exposed areas are filled with high alloy with high corrosion resistance. The Seal Air System is also required to prevent leaks in the Damper. This Seal Air System includes several instruments to maintain the temperature, such as the Steam Heater and the thermostatic valve, and the Steam Trap, Temperature Transmitter, Pressure Transmitter and Temperature Element to remove the condensate from the Steam Heater.
