[0014] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] Please see Figure 1 This utility model discloses a durable industrial combustion furnace, comprising: a combustion furnace body 1, a combustion furnace 2 disposed within the combustion furnace body, an air inlet 3 disposed at the bottom of the combustion furnace, an air outlet disposed at the top surface of the combustion furnace, and a feeding port 4. The feeding port has a funnel-shaped structure to facilitate the smooth falling of materials. The air inlet is connected to an air inlet pipe 5 for connecting to natural gas. An air inlet valve 6 is installed on the air inlet pipe to adjust the airflow, allowing the amount of natural gas to be adjusted as needed, avoiding unnecessary waste. The air outlet is connected to an air outlet pipe 7 that extends to the outside of the combustion furnace. An induced draft fan is installed inside the air outlet pipe to accelerate the discharge of combustion exhaust gas.

[0016] Specifically, from the inside to the outside, the combustion furnace and the combustion furnace body are provided with a reinforcement structure, a heat insulation structure 8, and a heat preservation structure 9. The support part and the frame part are made of metal. The reinforcement structure includes a reinforcement block, which includes a support part 10 that is attached to the side wall of the combustion furnace and a frame part 11 that is integrally formed with the support part. The support part is fixedly connected to the inner wall of the combustion furnace body by locking screws, which can press and fix the heat preservation layer and the heat insulation layer, and also improve the structural strength of the entire combustion furnace body. The frame part has at least two sets of hollow cavities 12, which reduces heat conduction.

[0017] Specifically, the heat insulation structure is formed by stacking two layers of ceramic fiber boards and a layer of calcium silicate board sandwiched between the two layers of ceramic fiber boards, and the heat preservation structure is formed by stacking 3-5 layers of heat preservation felt or heat preservation board. The materials are relatively light, which makes the entire furnace body more convenient to replace and move in the later stage, and reduces the difficulty of later maintenance and replacement.

[0018] Specifically, the outer wall of the combustion furnace body is coated with anti-corrosion paint to further extend its service life.

[0019] The beneficial effects of this utility model are: the materials of the heat insulation layer and the heat insulation layer are relatively light, and the locking bolts of the reinforced structure can press and fix the heat insulation layer and the heat insulation layer, while also improving the structural strength of the entire combustion furnace body and extending the service life of the combustion furnace.
