A combustion burner resulting in low oxides of nitrogen includes a primary combustion zone, for use as an ignition source. The primary combustion zone locating within a combustion chamber, and being separated from the base of the combustion chamber by a wall. A burner provides a secondary oxidant stream that is delivered to the combustion chamber at the base of an exterior wall, to entrain and mix with flue gases present in the combustion chamber. Then secondary fuel is injected into the resulting secondary oxidant-flue gas mixture. Combustion of the secondary fuel with the oxidant flue gas mixture results in lower concentration of oxides of nitrogen emitted to the atmosphere.
