Low NOx axial premix burner apparatus and methods for burning fuel gas are provided by the present invention. The methods of the invention are basically comprised of the steps of mixing a first portion of the fuel gas and all of the air to form a lean primary fuel gas-air mixture, discharging the lean primary fuel gas-air mixture into the furnace space whereby the mixture is burned in a primary combustion zone therein, discharging a second portion of the fuel gas into the primary combustion zone to stabilize the flame produced therein and discharging the remaining portion of the fuel gas into a secondary combustion zone in the furnace space.
