Abstract:
A furnace apparatus comprising:a housing; a combustion chamber disposed within said housing, said combustion chamber having a pilot flame; a fuel inlet passage in fluid communication with said combustion chamber, said fuel inlet passage being operable to selectively inject a fuel within said combustion chamber; an air inlet passage in fluid communication with said combustion chamber, said air inlet passage being separate and spaced apart from said fuel inlet passage, said air inlet passage being operable to selectively inject air within said combustion chamber, wherein during steady state said fuel and said air fluidly mix with existing combustion products within said combustion chamber prior to combustion to produce a generally homogeneous mixture within a reaction zone to promote generally uniform radiation transfer; and an exhaust passage in fluid communication with said combustion chamber, said exhaust passage being positioned so as to maintain a predetermined thickness of said reaction zone.
