20130199240 | METHOD AND SYSTEM FOR DEWATERING AND PREHEATING MIXTURES FOR GLASS MELTING PLANTS - A method and a system for thermal dewatering and preheating aqueous mixtures for feeding glass melting plants when passing through a shaft-like container provided with heating elements disposed one above another in tiers. To avoid the feed material from becoming glued together or agglomerating in the preheaters while the feed material is heated by exhaust gases with separately guided exhaust gases and feed material, a) the uppermost tier heating elements are closed relative to the mixture and are kept above 100 C, b) the interface between the mixture and the atmosphere above the mixture is shaped and heated by the uppermost tier heating elements so that part of the thermal output is emitted to the atmosphere via the mixture, and c) as the mixture proceeds through the container it is heated by further heating elements to temperatures close to the glass melting plant feeding temperature. | 08-08-2013 |
20130180287 | METHOD AND APPARATUS FOR FEEDING PREHEATERS FOR GLASS MELTING INSTALLATIONS - A method and an apparatus for feeding preheaters having heating elements for the feedstock of glass melting installations. In order to distribute the feedstock in an extremely thin, but uniform layer thickness on and between the upper heating elements, thereby effectively suppressing or avoiding agglutination of particles and accumulation of the feedstock, a distributor device is arranged above the topmost heating elements including at least three pivotable distributor plates, the pivoting axes of which run in the horizontal edges of a virtual prism. The topmost distributor plate throws the feedstock alternately onto one of the distributor plates arranged underneath, which throws the caught feedstock to one of its sides sternwards. The movements of the distributor plates are controlled by sensors with an evaluation and control circuit and actuators assigned to the distributor plates with the aim of a uniform area distribution of the feedstock over the cross section of the preheater. | 07-18-2013 |
20130114638 | GLASS MELTING TANK HAVING A DOGHOUSE, AND METHOD FOR HEATING THE CHARGE MATERIAL IN SUCH GLASS MELTING TANKS - A glass melting tank comprising at least one front part for introducing the charge material, and at least one charging device. To reduce atmospheric heat losses and reduce dust transport into the upper furnace of the tank, and nevertheless to intensify the heating of the charge material, the front part has a length “LV” of at least 2,250 mm in the direction of the melting tank, and a length “LG” of at least 1,200 mm is provided with an insulating roof. An end wall near the charging device, together with the roof, encloses a gas chamber open toward the melting tank. A characteristic value “K” of 3.50 tonnes (t) per hour and per square meter of surface is not exceeded. The characteristic value is calculated from P/F, where P is the throughput per hour in tonnes (t) and F is the inner surface of the front part in m. | 05-09-2013 |
20130091721 | DEVICE FOR DRYING AND PREHEATING PARTICULATE FEEDSTOCK - A device for drying and preheating particulate feedstock for glass melting apparatuses including a vertical shaft in which a plurality of gas guides are arranged level by level. The shaft has at least one gas channel for exhaust gases from the melting apparatus. a) feedstock guide elements are arranged one above another within the shaft with lateral spacings on all sides, with a portion of the gas guides extending through the guide elements, b) at least one of the guide elements is mounted in a transversely movable fashion with respect to the shaft independently of other guide elements, c) the guide elements are provided with converging oblique surfaces for introducing the feedstock at upper ends of the guide elements and with converging oblique surfaces for the emergence of the feedstock at lower ends of the guide elements, and d) at least one guide element is connected to a vibrating drive. | 04-18-2013 |
20120288812 | REGENERATIVE CHAMBER FOR A GLASS MELTING FURNACE - A regenerative chamber for a glass melting furnace having a defined cross-section and wherein the regenerative chamber includes multiple slotted arches and above the same there are disposed transfer layers, and wherein a grating is installed on the transfer layers. A movable flow barrier is provided above the slotted arches that is inserted from the outside into the regenerative chamber and by means of which the cross-section of the regenerative chamber can be reduced. | 11-15-2012 |
20120070252 | METHOD AND DEVICE FOR SUPPLYING GLASS MELTING FURNACES WITH FREE FLOWING GLASS MIXTURES - A method and a device for supplying free flowing glass mixtures by transport devices for feeding the glass mixture through a doghouse opening of a glass melting furnace above the glass level, and a pusher driven by a pusher arm for distributing the glass mixture on the glass melt. The transport devices and the pusher arm extend through the doghouse opening and at are least extensively sealed. To feed glass mixture into the furnace and to distribute it over the melt surface in a targeted manner, thereby extensively maintaining the sealing of the interior of the furnace from the surroundings, the glass mixture is applied to the glass melt by two adjacent transport devices and independently controlled with regard to the delivered quantity per unit of time, and is distributed over the glass melt by continuous rotary motions of the pusher at both sides of the pusher arm. | 03-22-2012 |
20120017643 | MELTING DEVICE FOR PRODUCING A GLASS MELT - A glass melting oven for producing a glass melt in a row arrangement, having a loading opening for raw glass materials, a melting region, a refining region, a constriction, a conditioning region and an overflow into a processing unit. To remove flaws from the melt that remain visible in the end product, a method includes the steps of a) arranging a refining bench between the melting region and the beginning of the refining region; b) arranging side burners and extraction openings for flue gases between the loading opening and the refining bench; c) delimiting the constriction at both ends by end walls that leave narrow flow cross-sections above the glass melt for flue gases; and d) cooling the glass melt inside the constriction. The glass melting oven is particularly suited for producing flat glass and panels for solar elements. The oxidants for the fuels may also be preheated. | 01-26-2012 |
