Which component controls the proper function of the burner in relation to air and fuel?

The component responsible for controlling the proper function of the burner in relation to air and fuel is the combustion controls. These controls are essential for maintaining the appropriate mix of air and fuel to ensure efficient combustion, preventing issues such as incomplete burning, excessive emissions, or unsafe operating conditions. Combustion controls can include various devices and mechanisms that monitor and adjust the flow of fuel and air to the burner, optimizing the combustion process for efficiency and safety.

Other components mentioned, such as the safety valve, pressure reducing valve, and feedwater regulator, play crucial roles in the overall operation of a steam system but do not directly manage the air-fuel mixture for combustion. The safety valve is designed to relieve excess pressure and prevent dangerous situations, the pressure reducing valve regulates the pressure of fuel or steam within the system, and the feedwater regulator controls the supply of water to the boiler. While these components are vital for system operation, they are distinct from the dedicated function of combustion controls in managing the burner’s performance.
