A method and apparatus are provided for reacting waste matter in a flame using fuel such as a flammable gas and oxygen. The apparatus includes a substantially cylindrical burner comprising a burner base and a removably attachable base extension having a diameter greater than that of the base. The base and the base extension each have aligned central nozzles extending their entire lengths for ejecting waste matter to be reacted, and aligned fuel nozzles radially spaced from each of the central nozzles for ejecting fuel to be ignited. The perimeter of the burner base extension is notched to provide channel-shaped peripheral oxygen nozzles. A substantially cylindrical cooling jacket surrounding the burner is adapted to receive oxygen which passes through the space defined by the outer surface of the burner base and the inner surface of the cooling jacket, then through the peripheral oxygen nozzles of the base extension. Other base extensions, having various peripheral nozzle shapes and central nozzle configurations, can be interchangeably attached to the burner base to create desired flow patterns of waste matter and oxygen through the central nozle and peripheral nozzles, respectively.

Apparatus and method for recycling waste

In a glass melting furnace of the type that has a basin wherein a bath of molten glass is heated by a blanket of flame that extends over the molten bath, performance and productivity are enhanced by installing oxygen injection lances through holes that are drilled through walls of the furnace at tuck stone levels just above the top surface of the molten bath of glass in the furnace basin. The lances are thin walled tubes that each carry an adjustable flange for preventing unwanted convection and radiation through furnace wall holes that receive the lances. By bending the thin walled tubes to carefully direct the discharging flows of oxygen so that the discharge paths properly extend across the top surface of the molten bath in closely spaced, parallel relationship thereto, and by selecting discharge opening sizes, the injected flows of oxygen are aimed and defined so as to effectively draw the blanket of flame down to surface portions of the molten material that is being heated, and to achieve complete combustion and maximum flame coverage. Thus both flame positioning and combustion efficiency are improved concurrently.
