What type of air do infrared burners require for optimal operation?

Infrared burners require optimal combustion conditions to function efficiently, which hinges on the proper supply of air necessary for the burning process. Primary air is the first air that enters the burner and mixes with the gas prior to combustion. For infrared burners, which operate at high efficiency and produce intense heat, they specifically need this primary air to ensure that the gas is mixed thoroughly and burns completely.

Using 100% primary air means that the air is mixed directly in the burner with the fuel before ignition, leading to efficient combustion and the generation of infrared radiation. This radiation is what provides the characteristic cooking heat associated with infrared burners. The correct balance of this air is critical, as any variation may affect the burn quality, efficiency, and safety of the burner.

Other air types, like secondary or mixed air, do not provide the optimal conditions necessary for infrared burners specifically. Secondary air usually refers to air that enters the combustion zone after the fuel has been combusted and does not contribute to the initial combustion mix needed for infrared operation.
