| 6909075 | Method and apparatus for heat treatment of raw materials Apparatus for heat treatment of raw materials for production of a melt includes a first chamber having a first chamber crucible, a first chamber inlet for a raw material leading to the first chamber crucible, at least one first chamber microwave generator, and a fir... | 06/21/2005 |
| 6339610 | Glass melting tank and process for melting glass A glass melting tank with at least one pair of heating electrodes projecting into the glass melt and a process for melting glass are described. The glass melting tank has, at least in the area of the melt, a narrowed cross section area and the glass melti... | 01/15/2002 |
| 6154481 | Method of operation of a glass melting furnace and a glass melting furnace for the practice of the method In a glass melting furnace, a radiation screen wall is installed between a melting area and a refining area with a refining bank. This radiation screen wall leaves a flow path above the melt surface of the glass bath for the return flow of at least part o... | 11/28/2000 |
| 5993049 | Method and system for calculating mass and energy balance for glass furnace reburn A method and system for determining a mass and energy balance for a glass furnace proceeds through a furnace model and calculates a number of parameters for the flows within each segment of the furnace. The mass flow rate, enthalpy, and enthalpy flow rate... | 11/30/1999 |
| 5659564 | Method and apparatus for maintaining a furnace stack The bottoms of exhaust stacks and systems on glass melting furnaces usually collect slag that is produced by volatiles in the exhaust gases condensing out and forming a glassy substance on the cooler walls of the stacks, etc. which then runs down the wall... | 08/19/1997 |
| 5327452 | Forehearth A forehearth for a glass furnace comprises a trough and roof over the trough, the roof having two longitudinal ridges extending downwardly towards the surface of the glass to define three longitudinal chambers. The central chamber forms a conduit for the ... | 07/05/1994 |
| 5243621 | Method of feeding glass batch to a glass-melting furnace A method of feeding glass to a glass-melting furnace for making a vitreous material, a heated airstream containing air at a temperature in excess of 1,000° C. is passed down vertical cylinders towards the crown of the glass-melting furnace. Powdered glas... | 09/07/1993 |
| 5173919 | Manipulation of the exit gas flow in a melting furnace In a melting furnace (1), toxic, volatile chemical compounds from introduced filter dust from industrial incineration units are vaporized at about 1300° C. and forced to leave the reaction space. The non-vaporizing residue forms a glassy melt which is di... | 12/22/1992 |
| 4903277 | Electric melting furnace with partitioned melting cavity for solidifying highly radioactive waste in glass An electric melting furnace for solidifying highly radioactive waste in glass has a melting cavity made of a non-conductive refractory and adapted to melt a raw material consisting of highly radioactive waste and a glass material by passing a current betw... | 02/20/1990 |
| 4752938 | Baffled glass melting furnaces There is disclosed a glass melting furnace having various forms of baffles located within the melt for dividing the furnace into zones and creating extended flow paths within the furnace for increasing the minimum residence time of the glass within the fu... | 06/21/1988 |
| 4388721 | Throat upwell baffle A chimney baffle is positioned against a vertical refractory wall extending from a channel through which hot glass is flowing to reduce deterioration of the refractory of the vertical wall.... | 06/14/1983 |
| 4367866 | Furnace adapted to contain molten metal A furnace to contain molten zinc, molten aluminum, or other molten metal has an outer vessel, an inner vessel, and particulate matter packed therebetween so as to enable the inner vessel to be lifted readily from the outer vessel. Electrical conductors ar... | 01/11/1983 |
