A roof mounted oxygen-fuel burner for a glass melting furnace can produce a variable moving or sweeping flame in the furnace and can also vary the flame shape. The burner has a housing having an oxygen inlet pipe coupled to an oxygen chamber and a fuel inlet pipe coupled to a fuel feeding crossover block. The fuel feeding block feeds fuel to a nozzle fuel port while the oxygen chamber feeds a plurality of nozzle oxygen ports which oxygen port outlets are angled toward the centralized fuel port outlet. A rotating impeller over the oxygen ports has a partial opening that causes a variable moving or sweeping flame in the burner as the impeller rotates. The impeller is also raised or lowered to control the flow of oxygen to the plurality of oxygen port outlets to control the shape of the burner flame.

Oxygen-fuel burner for a glass melting furnace

A low pressure atomizer is used for the atomization of liquids, such as atomization of fuels found in industrial burners. An atomizer body has an atomizing chamber therein and an annular liquid conduit having an annular diffusion member therein. The diffusion member is shaped to direct liquid passing thereby and into the atomizing chamber and forces the liquid to enter the chamber adjacent the walls thereof. The atomizer body has a first annular gas conduit and a tangential gas port connected between the annular gas conduit and the liquid conduit so that the gas impinges tangentially against the liquid to shear and rotate the liquid entering the atomization chamber. A second annular gas conduit has an angled open into the atomizing chamber to further shear the liquid and gas mixture in the atomizer chamber so that a low pressure atomizer atomizes a liquid with low pressure gas streams. A plurality of tangential gas ports connect the gas conduit to the atomizing chamber with the tangential ports being generally perpendicular to the gas conduit.
