Custom Dampers for Heat Recovery Steam Generators
Dampers from Kelair provide HRSG bypass systems with the critical accuracy and quality needed for optimal operation.
HRSG systems require highly reliable and durable dampers to enable the proper flow of gases in both single and multi-pressure exhaust systems. As a power source for large buildings, industrial facilities and plants, HRSG bypass “stack cap” dampers must support the necessary precise flow of exhaust gases so systems can effectively and efficiently shut down or pause operation when needed. Environmental regulations and concerns for reduced emissions demand the implementation of quality, durable damper systems to assist in diminishing or omitting nitrogen oxide and carbon monoxide emissions from HRSGs.
Why Choose Kelair for HRSG Bypass Dampers?
Kelair dampers are custom-made to accurately deflect gasses to HRSG Bypass stacks, which reduces energy consumption and emissions. Improved energy efficiency lowers operational costs and extends the lifespan of the equipment. Industrial operators rely on Kelair products to withstand the extreme temperature fluctuations, pressure and mechanical stresses of HRSG systems.

Butterfly dampers used by Kelair have the simplest design and the fastest turnaround. They are the economical choice for applications ranging from light duty to heavy duty and low temperature to high temperature.
Kelair's Louver Dampers are applicable for both light, and heavy-duty industrial ventilation for high volume flow control, and isolation applications. This damper modulates the flow of air and gas in dry or wet conditions or can shut them off altogether.
Slide Gate / Guillotine Dampers
These types of slide gate or guillotine dampers are used primarily as shut off devices. Kelair's rugged, heavy duty designs are available round or square with sizes from 4" up to 96" making them an ideal solution for industrial applications.
Diverter & Tee Dampers
Diverter Dampers or Tee Dampers are used to redirect air stream from one outlet to another. These types of dampers are widely used in incineration systems to divert process air and gas to the incinerator or by-pass to the atmosphere.
Kelair’s Refractory dampers are manufactured to withstand temperatures up to 1900 F in corrosive, particulate and/or process gas environments. This unique design helps reduce heat loss and provide erosion protection for the frame.
Inlet Vane Dampers
Inlet Vane Dampers work with fans and blowers to enhance their performance by controlling air volume and fan shut-off. Kelair’s design boasts no external linkage, eliminating pinch points and damage to the assembly.
Kelair’s Backdraft dampers are engineered to allow airflow in one direction and prevent reverse airflow. Backdraft dampers control airflow in ventilation systems either to modulate or to shut off moving air through a fan opening when it is turned off.
Stack Cap Dampers
Kelair's Stack Cap Dampers isolate the stack opening to prevent foreign material from entering and conserve warmth when the stack is shut down. The dampers deliver accurate airflow and isolation at high temperatures, reducing the stack effect.
