Abstract

The invention provides an oxy-fuel combustion furnace used in low-expansion microcrystalline glass manufacturing. The oxy-fuel combustion furnace used in low-expansion microcrystalline glass manufacturing is characterized in comprising a cuboid-structured cavity and a furnace cover positioned on the top of the cavity. A steel-structured fixing frame is arranged on the periphery of the cavity and the furnace cover. A feeding port is arranged on a long side of the cavity. A flue is arranged on a short side of the cavity, and a glass discharge port is arranged on the other short side of the cavity. A bottom wall is arranged on the bottom of the cavity. Tank walls are arranged on two sides of the bottom wall, such that a glass tank furnace is formed. Parapets are arranged above the tank walls on the two sides. More than one burning lances are arranged at a certain height above the parapets. The burning lances comprise natural gas inlets and pure oxygen inlets.

Description

technical field [0001] The invention relates to a device for firing glass-ceramics, in particular to an all-oxygen combustion kiln for producing low-expansion glass-ceramics. Background technique [0002] Due to the characteristics of high melting point and high molding temperature of low-expansion glass-ceramic, when it is melted in an ordinary air-assisted combustion furnace, there are many defects in the glass. Such as bubbles, stones, lines, etc.; at the same time, its molding temperature cannot be guaranteed, making glass molding difficult. Contents of the invention [0003] Purpose of the invention: The technical problem to be solved by the present invention is to provide an all-oxygen combustion furnace for the manufacture of low-expansion glass-ceramic for the deficiencies of the prior art. [0004] In order to solve the above technical problems, the present invention discloses an oxy-combustion kiln for the manufacture of low-expansion glass-ceramic, which includ...
