Glass furnace of improving cooling glass liquid in working pool and method for cooling glass

The glass smelting furnace has wall bricks which are around to limit a working tank, multiple firing guns arranged surround the working tank and used to jet mixed gas of air and natural gas ito the working tank, entrance and exit of cooling wind are set along perimeter of breast wall of the working tank in height higher than liquid level line of breast wall brick of the working tank and nearer position of the liquid level line than firing guns, said entrance and exit of cooling wind are connected by hollow wind passage fit in breast wall bricks in the working tank to make the forced controlled cooling wind send from cooling wind entrance to cooling wind exit through cooling wind passage direct acting to whole flame space higher than liguid level line of breast wall brick of the working tank effectively to realize forced controlled wind cooling and reduce temp, of glass liquid in the working tank, thus to improve quality of glass.
