What type of burner is used in conversion burners?

Conversion burners are designed to facilitate the modification of heating systems to switch from one type of fuel to another, often from oil to natural gas. The inshot burner is particularly suited for this purpose due to its design, which allows it to efficiently mix fuel and air, providing optimal combustion characteristics regardless of the fuel type.

Inshot burners draw in combustion air through the burner ports and mix it with the gas, allowing for precise control of the combustion process. This is especially important during conversions, as achieving the correct air-fuel ratio ensures clean and efficient burning, reducing harmful emissions and improving system performance.

The other types of burners mentioned do not possess the same versatility for fuel conversion as inshot burners. Ribbon burners, for example, are more commonly used in applications requiring broad flames but are not specifically designed for adaptability with various fuel types. Flash burners are usually employed in situations needing rapid ignition and large heat release but are less common for conversions. Purge burners, while important for system safety and preventing backdraft during startup, do not play a role in the conversion process. Thus, the inshot burner's capability to effectively manage the complexities of fuel conversion makes it the correct choice in this scenario.
