Abstract
A low NOx burner has a housing that includes a burner head defining a gas manifold and a primary flame zone downstream of the burner head. The burner has a gas inlet for receiving gas. Flow-through air vents are disposed around a center of the burner head and extending through the burner head thereby enabling cold core air to flow from an annular core space upstream of the burner head to the primary flame zone downstream of the burner head. The burner also includes a plurality of premix air vents in fluid communication with the manifold for premixing air and gas within the manifold and for emitting premixed air and gas into the primary flame zone. A plurality of staging pipes extend from the manifold into the primary flame zone for conveying gas into the primary flame zone. The burner includes an ignition device extending into the primary flame zone.
