The function of the middle partition wall of the three horizontal partition walls: it can control the direction of the glass liquid and fully discharge the air bubbles. The height of the three transverse partition walls is consistent with the pool wall bricks in the melting pool (electric fused bricks). It can not only block the glass liquid, but also allow the longitudinal flame to pass through the melting furnace smoothly.

The heat energy is consumed by adopting the longitudinal flame staying in the furnace for a long time. The temperature of the flame entering the regenerator is about 1000 degrees, which is about 300 degrees lower than that of the regenerator of the horseshoe kiln. The temperature of the regenerator is low and the service life is long. The present invention also has It features wide melting area, low discharge rate, and the melting temperature is designed around 1520 degrees, which can extend the service life of the melting furnace by about one time (about 15 years) compared with traditional melting furnaces (same material).

It is to set a cooling zone at one end of each bubble exhaust area (referring to the lateral direction of the melting pool) and the material inlet, and the glass liquid is cooled and then passed through the material inlet to form. One material intake on one side or one material intake on both sides is set in the middle of the long side of the melting pool, so as to realize single-line output from one kiln or multi-line output from one kiln.

The present invention changes the traditional horseshoe flame kiln into a longitudinal flame, the depth of the melting pool is determined according to the melting point of the raw material into the furnace, and the material is fed by the horizontal side pre-melting method, and the horizontal middle part is formed with a single line or two sides with multiple lines. Compared with traditional horseshoe-shaped furnaces, it can save energy by more than 30%, reduce _CO2 and _SO2 emissions by more than 30%, reduce raw material dust and particle emissions by more than 95%, greatly improve the quality of glass wine bottles, and extend the service life of furnaces by more than two times.
