摘要： A bottom heated holder furnace (10) for containing a supply of molten metal includes a storage vessel (20) having sidewalls (22) and a bottom wall (24) defining a molten metal receiving chamber (26). A furnace insulating layer (32) lines the molten metal receiving chamber (26). A thermally conductive heat exchanger block (50) is located at the bottom of the molten metal receiving chamber (26) for heating the supply of molten metal. The heat exchanger block (50) includes a bottom face (55), side faces (56), and a top face (57). The heat exchanger block (50) includes a plurality of electrical heaters (70) extending therein and projecting outward from at least one of the faces of the heat exchanger block (50), and further extending through the furnace insulating layer (32) and one of the sidewalls (22) of the storage vessel (20) for connection to a source of electrical power. A sealing layer (60) covers the bottom face (55) and side faces (56) of the heat exchanger block (50) such that the heat exchanger block (50) is substantially separated from contact with the furnace insulating layer (32). A gas pressurization valve (118) is in fluid communication with the molten metal receiving chamber (26) and the interior of the heat exchanger block (50) for pressurizing the interior of the holder furnace (10).

摘要： The present invention is for a method for heating of blanks and other heating of metallic materials in a furnace before working where heat is transferred to a blank in the furnace by radiation. According to the method of the invention an important part of the radiation hits the walls of the furnace and are reflected there before it is transferred to the blank. Preferably the furnace is designed so that heat radiation is reflected also at the bottom of the furnace. At least 50 % of the radiation which reaches the blank ought to be reflected radiation. The invention is also for a furnace for heating of blanks and other comprising at least one furnace bottom part (1) and at least one furnace top part (4) having side walls (5, 6, 7, 8) where at least parts of the side walls of the top parts are inclined so that opposite walls are inclined towards each other.

摘要： The disclosed cross-flame arrangement of cross-fired tank furnaces aims at a relative reduction of flame and roof temperatures in order to improve furnace performance and reduce nitrogen oxide. By partially deflecting fuel jets sideways out of the combustion air flow with several burners and orifice jewels, the starting reaction of the flame is subdued, a "cold" flame root is set, and NO is reduced. At the same time, a carburating effect is achieved, increasing the emission coefficient of the flame. Next to the furnace walls, therefore, it acts at first as a heat sink, but in the centre of the furnace, the heat emitted by the flame is intensified instead of its temperature (reducing its maximum values and NO emissions). The deflection of the flames into a fan flame pattern also increases flame length and the extent of coverage of the melt surface by the flames, lengthens the path of the flames and shortens the path of thermal radiation to flame-distant areas of the glass bath surface. Flame position may be vertically adjusted to give a uniform distance from the molten glass. The temperature in the upper part of the furnace is relatively reduced, lowering NO emission and increasing melting capacity. The improved heat radiation lowers the temperature at the outer end of the flame. In addition, the temperature reduction next to both furnace walls increases glass transverse flow in the lower part of the furnace, improving its performance.
