    Abstract: A method and burner apparatus for heating and continuously melting a non-ferrous material charge, such as copper pieces in a furnace without contaminating the material charge in the furnace with non-vaporized liquid fuel thereby maintaining the metallurgical quality of the non-ferrous material charge.

    Abstract: An improved premix gas burner design suitable for use in a metal melting furnace which has long service life, a low degree of maintenance, is easily cleared in case of burner blockage, allows inspection of the combustion chamber or furnace interior and still maintains the desired turndown capabilities of premix gas burners. These results are achieved by providing usual and/or physical access to the interior of the burner through a novel access tunnel and by providing a dual composition refractory combustion chamber.

    Abstract: An improved vertical furnace for melting metal pieces, such as pieces of copper cathode. The furnace has a generally round interior wall of refractory brick material which encloses a vertical melting chamber having a plurality of burner openings through the refractory wall. Heat, being injected through these openings by means of a novel burner design, melts the metal pieces under metallurgically controlled conditions. The burners are arranged near the bottom floor of the melting chamber which is sloped toward a single outlet thus allowing the molten metal to continuously drain from the melting chamber. The burners are fed a mixture of fuel and air from a plurality of remote mixing stations so as to reduce turbulence at the burners thereby significantly reducing the operating noise level and refractory wear compared to prior art furnaces. A combustion chamber between the burner and the melting chamber is provided so as to prevent entry of uncombusted fuel and/or air, thereby maintaining the closely controlled atmosphere in the melting chamber.
