Ultra Low NOx Emission Burners
Ultra low NOx burners are required in many areas of California as well as several other states. All of ALZETA®’s burner technologies can deliver less than 7 ppm NOx in most applications. Key to achieving reliable and repeatable results is our premixed, surface-stabilized combustion that provides uniform heating and operates at minimum combustion temperatures.
Combustion temperatures are minimized by operating lean (lower fuel-to-air ratio). This may be achieved by simply increasing combustion air, or diluting with flue gas or another inert gas. While other burners may encounter combustion instability at the lean conditions needed for ultra low NOx, ALZETA’s surface-stabilized combustion is complete and uniform. Heat transfer remains effective within the furnace or combustion chamber, flame length is unchanged and predictable, and CO emissions remain low. These characteristics also make ALZETA’s low emission burners ideal for operation on low Btu content fuels such as biogas or digester gas, in that the inert gases contained in the fuel further reduce combustion temperatures. NOx emissions are similar or lower than with conventional fuels.
ALZETA's Low NOx Combustion Technology
For areas where ultra low NOx regulation is pending or anticipated, an equipment owner can install an ALZETA burner now and operate it as a low NOx burner to receive the benefits of uniform heat distribution, simple controls, and quick response; while knowing that the burner technology can be adjusted to comply with future lower NOx requirements.
