Abstract

NOx reduction apparatuses for use in heat exchangers or furnaces, HVAC units and buildings having such devices, and methods of making such devices. Wire embodiments may have a body, helix, or modified helix, and support members that extend outside the body to hold the body away from the heat exchanger or tube. The support members may be made of the wire, and may include bights, twisted bights, or larger (e.g., helical) turns, for instance, between groups of smaller helical turns. In some embodiments, a modified helix is formed by alternating bends and straight sections of wire. Some embodiments include an attachment mechanism that may be made from the wire and may include a hook. Wire may be Nichrome.
