[0040] The gas regenerator chamber 6 is built with checker bricks. Its main function is for reversing heat storage, recovering the waste heat of the flue gas in the furnace 1, and preheating the gas. After the gas passes through the gas regenerator chamber 6 from top to bottom, it can be heated to about 1300 degrees Celsius, and then enters the three small furnaces 5 on the left through the gas riser. After pre-combustion, it is sprayed into the interior of the furnace 1 through the nozzles 11 of the small furnaces 5 to form a transverse flame for heating the glass raw materials.

[0051] The working process of this device is as follows: First, the gas regenerator 6 is made of checker bricks. Its main function is to reverse heat storage, recover the waste heat of the flue gas in the furnace 1, and preheat the gas. The gas can be heated to about 1300 degrees Celsius after passing through the gas regenerator 6 from top to bottom, and then enters the 3 small furnaces 5 on the left through the gas riser. After pre-combustion, it is sprayed into the interior of the furnace 1 through the nozzles 11 of the small furnaces 5 to form a horizontal flame for heating the glass raw materials. Then, the air regenerator 7 is also made of checker bricks, which recovers the waste heat of the flue gas in the furnace 1 and heats the combustion-supporting air. The heated air enters the 3 small furnaces 5 on the left, and the temperature of the heated air is about 1300°C. After mixing with the preheated gas, the flame is sprayed into the furnace 1 through the furnace openings of the small furnaces 5. If the gas supply is stopped, the side-inserted natural gas spray gun 4 will supply natural gas. At this time, the air and natural gas are mixed in the small furnace 5 to form a flame and are sprayed into the interior of the furnace 1. The 3 small furnaces 5 on the left are located above the gas regenerator 6, and their bottoms are connected to the gas riser. The tails of the small furnaces 5 are connected to the air regenerator 7, and the preheated air directly enters the interior of the small furnaces 5. The gas regenerator 6 and the air regenerator 7 are connected by a built-in fire and wind partition wall. The tails of the 3 small furnaces 5 on the right are the same as those of the air regenerator 7. After the heated hot air enters the small furnaces 5, it will be mixed with natural gas to form a flame and be sprayed into the interior of the furnace 1. When only gas is used, the gas in the gas regenerator 6 and the air in the air regenerator 7 enter the small furnaces 5 for pre-combustion and then form a flame that is sprayed into the interior of the furnace 1 through the nozzles 11. When only natural gas is used, first insert the natural gas spray gun 4 into the side socket of the natural gas spray gun 10. After opening the natural gas pipeline, the natural gas enters the small furnace 5, is pre-combusted with the preheated air, and then forms a flame that is sprayed into the interior of the furnace 1 through the nozzle 11. Finally, through the electro-fusion hole bricks 8 located at the bottom of the furnace 1, electrodes are inserted, which can assist in melting the glass liquid and reduce fuel consumption. The working section 9 and the furnace 1 are connected by a liquid flow hole. The homogenized glass liquid in the glass furnace 1 enters the working section 9 through the liquid flow hole, is further homogenized, and then cooled to a certain temperature to prepare for glass forming.
