A fan assist burner is primarily designed for?

Better combustion
Conversion boiler
Overcoming appliance friction
Overcoming burner resistance

The correct answer is: Overcoming burner resistance

A fan assist burner is primarily designed to enhance the performance of the burner by providing a controlled supply of combustion air. This is especially important in overcoming burner resistance, which is the natural opposition within the system that can restrict the flow of air necessary for efficient fuel combustion. By utilizing a fan, the burner ensures that adequate air is delivered, improving the overall efficiency of combustion. This design improves the mixing of fuel and air, leading to more complete combustion, which results in higher efficiency and reduced emissions. Therefore, the correct answer highlights the fan's crucial role in aiding airflow against burner resistance, ensuring optimal operation of the gas appliance.
