Burner Controls

    What are Combustion Controls?

    Control systems can range from simple to increasing complex. The more elaborate systems have multiple sensors monitoring Oxygen levels in the exhaust, flame safeguard, fuel flow, fuel-air ratios, and more. The burner control is connected to motors that can adjust valves related to the sensors. The valves can be fitted with individual servomotors or actuators for precise control versus the common used mechanical linkage where a single motor controls all the valves through position of the linkage rod. An example would be if the exhaust has too much Oxygen that is an indictor of incomplete combustion, so the control adjusts the blower motor to a lower rpm so that less air is being used for combustion.

    How can a better Combustion Control System save on operating costs?

    Instead of a high-lo-off control, a modulating burner control system allows for precise control of the flame. With the precise control of the flame energy savings can be made because of the exact attunement to hit the loads. An outdoor temperature sensor can signal the boiler how much hot water the boiler needs to output to match the required indoor temperature.
