A hexagonal nut 15 is fixedly connected to the bottom of the bidirectional screw 14, and the outside of the bidirectional screw 14 is threaded... Two movable plates 16 are connected to the furnace cover 7. Multiple insert rods 17 are fixedly connected to one side of the movable plates 16, and two fixing blocks 18 are fixedly connected to one side of the insert rods 17. The insert rods 17 and fixing blocks 18 pass through the insert blocks 11 and the limiting blocks 12 and engage.

[0026] Reference Figure 1 As shown, the recovery mechanism includes a flue 19, one end of which is connected to the outside of the combustion furnace 1. A circulating fan 20 is fixedly connected to one side of the combustion furnace 1. The bottom of the input of the circulating fan 20 is connected to a connecting pipe 21, one end of which is connected to one side of the flue 19. The output of the circulating fan 20 is connected to a conveying pipe 22, one end of which is connected to the combustion furnace 1. Under the action of the circulating fan 20, the flue gas in the flue 19 can be extracted, and after flowing in the connecting pipe 21, it forms low-temperature flue gas, which is then conveyed to the inside of the combustion furnace 1 through the conveying pipe 22. This can preheat the fuel and oxidant, improve the combustion conditions, increase the combustion efficiency, and reduce the oxygen concentration and temperature in the combustion zone, thereby inhibiting the generation of thermal nitrogen oxides.

[0027] Working principle of this utility model: This utility model designs a high-temperature resistant and corrosion-resistant boiler device, the specific structure of which is shown in the attached instruction manual. Figure 1-7As shown, in this technical solution, through the cooperation between various structures, when the furnace body 3 is heated, the high-temperature resistant layer 4 and the anti-corrosion layer 5 on the inner side of the combustion furnace 1 and the outer side of the furnace body 3 can provide high-temperature resistance and anti-corrosion performance, which can reduce the high-temperature oxidation and corrosion of the substrate under high-temperature environment. The flue gas heated at high temperature is discharged through the flue 19, and then the circulating fan 20 is started. The circulating fan 20 can extract the flue gas discharged from the flue 19 through the connecting pipe 21. Due to the long length of the connecting pipe 21, the flue gas temperature can be reduced when flowing inside the connecting pipe 21, turning into low-temperature flue gas. Under the action of the circulating fan 20, the low-temperature flue gas can be transported to the inside of the combustion furnace 1, thereby reducing the combustion intensity. When it is necessary to clean the inside of the combustion furnace 1 and the furnace body 3, firstly First, rotate the hexagonal nut 15 using a tool, so that the hexagonal nut 15 can drive the double-ended screw 14 to rotate. Utilizing the symmetrical thread direction on the outer side of the double-ended screw 14, the double-ended screw 14 can drive the two movable plates 16 to move relative to each other through the threads. This allows the movable plates 16 to drive the multiple insert rods 17 and the fixing block 18 to separate from the limiting block 12. Then, rotate the furnace cover 7. The furnace cover 7 can drive the two sliders 10 to slide inside the slide groove 9 through the second flange ring 8. The two sliders 10 can be rotated to the opening at one end of the slide groove 9, and the furnace cover 7 can be lifted upwards to complete the removal of the furnace cover 7. Similarly, rotate the two sliders 10 inside the slide groove 9, and at the same time, the second flange ring 8 can drive the two insert blocks 11 to insert into the limiting block 12. Then, rotate the two hexagonal nuts 15 in sequence to complete the installation.
