<p>A method and system for enhancing the supply of combustion air delivered to a burner of a furnace to increase productivity and thermal efficiency of the burner while minimizing changes to the nominal combustion ratio of the burner are disclosed. Oxygen and fuel are introduced into an air plenum upstream of the burner assembly in controlled quantities to form a nonflammable premix of pressurized gases in the air plenum formed from the air, fuel, and oxygen. The air plenum has an outlet that communicates the nonflammable premix of pressurized gases to the burner for combustion. The nonflammable premix of pressurized gases has a predetermined percentage level of oxygen and a predetermined percentage level of fuel.</p> |
