Custom Industrial Dampers for Waste Incineration from Kelair Products
Kelair dampers are critical for hospitals and large manufacturing companies to take the necessary safety precautions to maintain a controlled balance of gases and healthy air quality for their employees.
Additionally, with an increase in environmental regulations on pollutants, dampers help support a healthy environment by diminishing their emissions through efficient combustion. Inefficiency when burning some of the most hazardous and unstable elements of waste is a recipe for disaster.
The Role of Waste Incineration Dampers
Using Air & Flue Gas Dampers
Through the incineration of gas, coal, solid waste, hazardous waste, or medical waste, a consistent flame zone is essential for improved ash quality and diminished incombustible leftover waste, bottom ash.
The complex process of waste incineration demands adequate attention to damper control systems and the quality of their functionality in preventing unstable gases or pollutants from escaping directly into the flue. The incineration equipment must maintain a necessary extreme temperature over an extended period of time, obtainable through the regulation of well-designed and installed dampers.

Butterfly dampers 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 light duty industrial ventilation to heavy duty, high volume flow control and isolation applications. Parallel or opposed blade, outboard bearings and linkage, adjustable packing glands and double skin airfoil vanes are all standard on louver dampers from Kelair.
Slide Gate / Guillotine Dampers
These types of slide gate or gullotine 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 also called Tee Dampers are used to redirect air stream (hot gas or otherwise) 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. Refractory dampers from Kelair help reduce heat loss to surroundings 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. They can be mounted to the fan inlet to conserve power at reduced airflow. These types of dampers reduce fan pressure without reducing speed. 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. They are typically wall or roof mounted and applied to mechanical HVAC ventilation systems. 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. Backdraft dampers can utilize pneumatic or electric actuators or be gravity controlled.
Stack Cap Dampers
Stack Cap Dampers or Stack Isolation Dampers both isolate the stack opening to prevent foreign material from entering when not in use and conserve warmth when the stack is shut down or during maintenance. Kelair’s Stack Cap dampers deliver accurate air flow and isolation at high temperatures and high volumes, reducing the stack effect when offline thereby protecting ductwork from the elements.
