Abstract
A method and apparatus for a burner adapted to heat a furnace or other environment of use. In particular, a burner for providing a fuel gas in combination with an oxidant to effect controlled reaction of the fuel gas in a manner to reduce NOx emissions is described. Combustion of the fuel gas is shifted from the burner combustor to a location outside the burner once the temperature within the furnace/radiant tube has reached a sufficient level to complete combustion of the fuel gas.
