Latest Patents
His latest patents include the "Ceramic radiant tube heated aluminum melter and method of melting." This invention discloses a method and apparatus for clean, low loss melting of aluminum using heat transfer by convection and radiation in separate stages. Heat input to a melter stage is provided by silicon carbide tubes into which gas-fueled burners fire, allowing the tubes to radiate heat to a molten aluminum bath. The combustion products exiting the silicon carbide tubes pass through recuperators, preheating burner combustion air. These products are then piped to a preheater stage and formed into jets of hot gases, which are directed into convective contact with solid aluminum stock as it is transported along a conveyor, preheating the stock to a temperature of about 1,000°F. The solid stock is then fed to the charge zone of the melter stage and melted by contact with the molten bath.
Another significant patent is the "Jet impingement/radiant heating apparatus." This heat-treating apparatus includes an insulated furnace compartment through which stock to be heat-treated is passed. Perforated tubes are arranged in the furnace and heated to radiance by burners, which also generate products of combustion that are ejected through the perforations at high velocity to impinge upon a surface or surfaces of the stock being heat-treated. The combination of radiation and convection, enhanced by the impingement of the jets upon a surface of the stock, provides highly efficient primary heat transfer. The burners are designed to ensure that rapid combustion takes place at a point removed from the perforations to avoid flame issuing from them. The tubes are sized and spaced to enhance secondary heat transfer from gases in the furnace compartment and from the walls of the compartment to the stock.
