A burner provided for low NOx combustion of fuel with preheated combustion air in a combustion chamber of an industrial furnace and or a steam boiler has a plurality of fuel jets and at least a single air jet arranged to discharge the fuel and the preheated combustion air. The fuel jets and the air jet diverge from one another, provide dilution of fuel with combustion products, and generate multiple precombustion, combustion and post combustion reaction zones in the furnace. Thus, the burner provides the necessary process conditions and reaction zones required for minimizing the formation of prompt and thermal NOx in the precombustion and combustion reaction zones and for optimizing the decomposition of the formed NOx in the postcombustion reaction zones.
