Where might I need a Damper Motor?
Burner Control
Burner Control
Combustion systems, such as boilers or furnaces, require a precise mixture of fuel and air for efficient combustion. A damper motor can regulate the airflow by adjusting the position of the dampers, ensuring the optimal amount of air is supplied to the burner. This helps achieve proper combustion and maximize fuel efficiency.
Flue Gas Exhaust
Flue Gas Exhaust
After combustion, the flue gases need to be safely discharged from the system. Dampers are used in the flue gas exhaust path, and a damper motor controls their opening and closing. This allows for proper venting of the combustion by-products, maintaining the required draft and preventing the buildup of dangerous gases.
Safety and Control
Safety and Control
In combustion systems, safety is of utmost importance. Damper motors can be integrated with safety controls and sensors to ensure proper functioning of the system. For example, a damper motor can respond to flame detection sensors or pressure switches, instantly closing the dampers in case of a malfunction or unsafe condition.
Turndown Ratios
Turndown Ratios
Some combustion systems may have the ability to modulate their output based on demand. A damper motor can be utilized to control the air supply and adjust the turndown ratio of the burner. This allows for efficient operation of the system across a wide range of loads and ensures optimal combustion performance.
Emissions Control
Emissions Control
Controlling the airflow through the dampers can also help manage emissions in combustion systems. By adjusting the damper position, the amount of excess air supplied to the combustion process can be optimised, leading to reduced emissions of pollutants such as nitrogen oxides (NOx).
