The function of a combustion regulator in a low pressure boiler is primarily to manage the fuel supply to the combustion process, which directly impacts the efficiency and effectiveness of the heating system. It adjusts the amount of fuel that is delivered to the burner based on the required heat output. By maintaining the correct fuel flow, the combustion regulator helps to ensure that the proper air-to-fuel ratio is achieved, which is essential for optimal combustion and energy efficiency.

While maintaining water temperature, controlling steam pressure, and preventing overheating are all important aspects of a boiler's operation, they are not the primary functions associated with a combustion regulator. Instead, these functions are typically handled by other components within the boiler system, such as temperature controls, pressure switches, or safety devices. Understanding the specific role of the combustion regulator highlights its importance in achieving reliable combustion and overall boiler performance.
