What is the function of a burner in a boiler system?

The burner in a boiler system plays a crucial role in the combustion process. Its primary function is to mix fuel—such as natural gas, oil, or another combustible substance—with air to ensure that a proper mixture is achieved for efficient combustion. Once this mixture is prepared, the burner ignites it, producing heat as a result of the combustion reaction. This heat is then used to raise the temperature of the water in the boiler, ultimately generating steam or hot water for heating purposes.

This operation is critical because the efficiency and effectiveness of a boiler are largely dependent on how well the fuel and air are mixed and ignited. The heat generated then enters the system, helping to manage the heating needs of a building or facility. Understanding the burner's function is essential for maintaining boiler efficiency, safety, and performance.
