20120137736 | GLASS-MELTING FURNACE, PROCESS FOR PRODUCING MOLTEN GLASS, APPARATUS FOR PRODUCING GLASS PRODUCTS AND PROCESS FOR PRODUCING GLASS PRODUCTS - The present invention provides a glass-melting furnace etc. which can maintain homogeneity of molten glass in an apparatus and a process for producing molten glass by melting glass raw material particles and glass cullet pieces. | 06-07-2012 |
20120137737 | PROCESS FOR PRODUCING MOLTEN GLASS, GLASS-MELTING FURNACE, PROCESS FOR PRODUCING GLASS PRODUCTS AND APPARATUS FOR PRODUCING GLASS PRODUCTS - The present invention provides a process for producing a molten glass which can produce a molten glass having a good quality, a glass-melting furnace, a process for producing glass products and an apparatus for producing glass products. | 06-07-2012 |
20120151966 | GLASS MELTING FURNACE, PROCESS FOR PRODUCING MOLTEN GLASS, APPARATUS FOR PRODUCING GLASS PRODUCT, AND PROCESS FOR PRODUCING GLASS PRODUCT - The present invention provides (i) a glass melting furnace, (ii) a process for producing molten glass, (iii) an apparatus for producing a glass product, and (iv) a process for producing a glass product, which are capable of preventing deterioration of the quality of molten glass caused by deposition of particles floating on a wall of the furnace. The melting furnace described herein includes a melting tank in which a flue located substantially at the center of a ceiling wall and a number of first heating units are disposed, such that particles floating in the furnace are suctioned off by a suction power of the flue and discharged from the furnace without being directed to a surrounding furnace wall. This drastically reduces the amount of floating particles deposited on the furnace wall, which prevents damage to the furnace wall and deterioration of the quality of glass produced therein. | 06-21-2012 |
20120159992 | GLASS-MELTING FURNACE, PROCESS FOR PRODUCING MOLTEN GLASS, APPARATUS FOR PRODUCING GLASS PRODUCTS AND PROCESS FOR PRODUCING GLASS PRODUCTS - A glass-melting furnace, which suppresses the effect of exhaust gas on molten glass quality, a process for producing molten glass, and a process and apparatus for producing glass products. The glass-melting furnace containing: a raw glass material particle feed portion disposed downwardly at a furnace wall portion in an upper portion of the glass-melting furnace; a heating unit provided under the feed portion, which forms a gas phase portion for converting raw glass material particles into liquid glass particles; a flue inlet disposed on the upstream side of the gas phase portion in a flow direction of the molten glass liquid; a furnace-bottom portion, which accumulates the liquid glass particles that produce the molten glass liquid; and a discharge portion, which discharges the molten glass liquid. | 06-28-2012 |
20120159994 | GLASS MELTING FURNACE, PROCESS FOR PRODUCING MOLTEN GLASS, APPARATUS FOR PRODUCING GLASS PRODUCT, AND PROCESS FOR PRODUCING GLASS PRODUCT - An apparatus for producing molten glass, a process for producing molten glass, an apparatus for producing a glass product and a process for producing a glass product, which are capable of preventing deterioration of the quality of molten glass caused by deposition of scattered particles on a furnace wall or a flue. In the present invention, together with the operation of introducing and melting glass material particles by an oxygen combustion burner, glass cullet pieces are dropped from glass cullet pieces-introducing tubes to form a substantially cylindrical enclosure around a flame by a flow of glass cullet pieces. That is, glass cullet pieces are dropped from eight glass cullet pieces-introducing tubes to partition off the furnace wall from the flame. And, particles scattering from the flame are captured as deposits on the surface of falling glass cullet pieces and dropped into a glass melt in the melt reservoir. | 06-28-2012 |
