The regionally coated noble metal element used in glass production has an uncoated region for contacting a glass melt and an H2-impervious layer or an H2-impervious and O2-impervious layer on a side opposite from the uncoated region, which has a layer thickness ≧1 mm, is heat-resistant, and is either liquid or solid. This layer is made from at least one glass or glass mixture, an at least partly crystallized glass or a ceramic material. The coated noble metal element can be a Danner channel, a Vello draw head, an A-draw head, a Vello needle, a drawdown needle, a discharge ring or a Danner blowpipe. A process for coating a noble metal element to produce the regionally coated noble metal element is also described.

An apparatus for preheating a batch (12) of glass cullet which is preferably enriched with raw materials for glass production, comprising a bunker (14) and flow ducts (22) formed therein, wherein the bunker (14) comprises a plurality of flow ducts (22) which are arranged vertically, and if appropriate offset, one above another and extend at an angle in relation to the vertical, in particular horizontally, wherein each flow duct (22) is composed of a profiled section (34) for forming an upper half thereof and also a heap of the batch (12) of glass cullet which is formed underneath the profiled section and forms the lower half of the flow duct (22), and wherein the profiled section has at least two limbs (36a, b) which laterally delimit the space between them. To reduce the flow rate in the flow ducts (22), at least one limb (36a, b) of the profiled section (34), preferably both limbs, has at least one convexly curved region (46) and/or a first uncurved region (40) which has a first angle of inclination in relation to the horizontal and is adjoined by an uncurved second region (42) with a different angle of inclination, and/or in that, in order to reduce the flow rate in the flow ducts (22), at least two (22a, b, c) of the flow ducts (22) which are arranged directly, and if appropriate offset, one above another are connected to a common feed line (26a) in the sense of a parallel connection with respect to the direction of flow.
摘要:
A method for supplying heat to a melting furnace for forming a molten product using ash-containing fuels. A fuel having an ash component is introduced into a slagging chamber of a slagging combustor and at least partially combusted with a first oxidant mixture and a second oxidant mixture within the slagging chamber. Ash component is collected as a layer of molten slag in the slagging chamber. Slagging combustor gas effluent is passed from the slagging chamber of the slagging combustor into the combustion space of the melting furnace at high temperature to supply heat to form the molten product. Molten slag is withdrawn from the slagging chamber of the slagging combustor and may be selectively introduced into the melting furnace or not introduced into the melting furnace.

Incinerator ashes, which is obtained after treating municipal solid waste, incinerator ashes or its plasma vitrified slag is made into mineral fibers. Cullet is added during manufacturing the mineral fibers for conditioning. The mineral fibers thus obtained have a good strength and could raise value of recycled product. In addition, it could reduce impact of the incinerator ashes to the environment and environmental protection is achieved.
摘要:
Certain preferred embodiments of the present invention provide a system for and method of analyzing and cleaning a cullet stream prior to bottle manufacturing. In accordance with certain aspects of the present invention, the system includes a raw materials feeder, a mixing stage, a melting stage, a bottle-forming stage, a cooling/annealing stage, an inspection stage, and a batch controller. The raw materials feeder further includes a cullet bin within which is cullet supply, a feeder, an analysis device, and removal assembly. Certain preferred embodiments of the method include the steps of feeding cullet onto the conveyor, performing real-time composition analysis of the cullet, removing contaminants from the cullet, determining whether the cullet batch is consistent with a predetermined tolerance threshold, adjusting the glass batch formulation, sending the batch ingredients to the mixing stage, and then completing the overall glass manufacturing process.

Methods of creating a batch of recycled glass from mixed color glass cullet. In one embodiment, the method includes receiving at a glass plant a weight and color composition percentage of a first batch of mixed color cullet. The glass plant also receives a weight and color composition percentage of a second batch of mixed color cullet. The weight and color composition percentage of the first batch and the second batch are combined to generate a combined weight and composition percentage. The combined weight and composition are percentage are used to generate, automatically at a glass plant, a formulation to produce glass of a desired color.
摘要:
A memorial for deceased humans or animals in which the cremated residue or ash is blended or mixed with particulate glass, the mixture being heated to form a liquid pool of glass with the cremation residue or ash dispersed, infused and/or absorbed therein, the molten glass and ash being removed from the heat source after a suitable time period and transferred to a mold in the shape of the memorial, the mold allowed to cool until the memorial sets, the memorial then removed from the mold and reheated in an annealing oven at a suitable temperature for a suitable time so as to eliminate possible cracking and scoring, the memorial once removed from the annealing oven can be further cut, polished, faceted, engraved or the like. The initial mixture of particulate glass and cremation residue and ash can be further combined with a coloring agent if so desired before heating or before transfer to the memorial mold.
摘要:
The present invention provides a two stage process of thermal separation of CFCs and HCFCs followed by vitrification of the waste into a commercially viable glass. In the first stage, the hydrogenated compounds are reacted at elevated temperature with water and a metal oxide such as calcium oxide to form a halide salt and carbon dioxide. In the second stage of the process, the brine slag is reacted at elevated temperature with the carbon dioxide from stage one and glass-forming raw materials such as silicon dioxide to produce a glass. The final glass product incorporates the halide into the glass.
