Glass melting furnace runner port flaming heating device

Abstract

The invention discloses a glass melting furnace runner port flaming heating device which comprises a sprayer, a first connecting pipe and a second connecting pipe. The sprayer comprises a shell with an inlet end and an outlet end and a flaming assembly arranged in the shell, and the inlet end and the outlet end are oppositely arranged vertically; the first connecting pipe is used for conveying compressed air into the shell, the second connecting pipe is used for conveying natural gas into the shell, and the natural gas and the compressed air can be conveyed to the outlet end of the shell through the flaming assembly. The flaming assembly comprises a plate assembly, a positioning plate and a fire gathering plate, and the plate assembly is closer to the first connecting pipe than the positioning plate; the plate assembly comprises at least one plate unit, and each plate unit comprises a first plate, a second plate and a focusing plate which are sequentially arranged from top to bottom. The flaming heating device can continuously provide heat energy, natural gas can smoothly and uniformly pass through the sprayer, and the natural gas and the compressed gas are fully mixed so that thesufficient and balanced combustion is ensured.

Description

technical field [0001] The invention relates to the field of glass production systems, in particular to a flame-spraying heating device for a flow channel opening of a glass melting furnace. Background technique [0002] In the prior art, both sides of the overflow of the glass melting kiln (glass liquid flows from the overflow of the glass melting kiln to the calender) are open, and the heat loss is fast, resulting in the temperature of the glass on both sides of the overflow being about 100°C lower than the central temperature. Cold glass liquid is likely to be generated on both sides of the runner opening, resulting in crystallization on the surface of the formed glass, which affects the quality of the glass. At present, although there are insulation measures on both sides of the flow channel of the melting kiln, the opening of the flow channel is the position where the molten glass contacts the outside world, and the temperature of the molten glass on both sides of the f...
