and S08, welding a patch 12 at the notch 11 at the other end of the furnace body 1.
The second method for installing the heating device provided by the embodiment of the application is different from the first method in which the patches 12 are welded after the pipe joints 5 at the two ends of the furnace body 1 are welded, and the second method is to weld the patches 12 at the corresponding gaps 11 after the pipe joints 5 at the two ends are welded on the furnace body 1.
Therefore, compared with the installation method of the first heating device, the installation method of the second heating device provided in the embodiment of the present application only involves adjustment of the installation sequence of the patches 12 at the two ends of the furnace body 1, and has no substantial influence on the structure and performance of the heating device itself, so the installation method of the second heating device has the same technical effects as the installation method of the first heating device, and is not described herein again.
In one embodiment, referring to fig. 2, the present application provides a method for installing a heating apparatus, in which a coil 2 includes an outer coil 21 and an inner coil 22 disposed inside the outer coil 21, and in this case, the step of welding a coupling 5 to one end of the coil 2 for S2 and S02 includes: a pipe joint 5 is welded to one end of the inner coil 22 and the outer coil 21, respectively. And S5 and S06, the step of welding another pipe joint 5 to the other end of the coil pipe 2, comprising: and the other pipe joint 5 is welded at the other ends of the inner coil pipe 22 and the outer coil pipe 21 respectively.

In order to prevent heat from being dissipated to the outside of the furnace body 1 through the gap between the outer coil pipes 21, after the outer coil pipes 21 are installed, the outer coil pipes 21 need to be axially positioned by the limiting blocks 3 so as to compress the outer coil pipes 21 and ensure that each layer of spiral steel pipes of the outer coil pipes 21 are tightly attached.
In addition, the baffle rod 4 is arranged, so that the inner coil 22 and the outer coil 21 can be arranged at intervals to form an annular flue 23. The installation height of the baffle rod 4 is determined according to the design size of the annular flue 23 and the diameter of the baffle rod 4.

a fixing piece 13 is welded on the outer wall of the furnace body 1 at the notch 11. The strength and the sealing performance of the furnace body 1 at the notch 11 can be further enhanced by welding the fixing piece 13, and the reliability of the connection between the pipe joint 5 and the furnace body 1 is ensured.
It is understood that the fixing pieces 13 may be welded to the outer wall of the furnace body 1 at the notch 11 before the patch 12 is welded to the notch 11 of the furnace body 1, or the fixing pieces 13 may be welded to the outer wall of the furnace body 1 at the notch 11 after the patch 12 is welded to the notch 11 of the furnace body 1. However, the fixing piece 13 should be welded after the pipe joint 5 is welded.
Further, in one embodiment, the fixing plate 13 has an opening (not shown) that allows the fixing plate 13 to avoid the coupling 5. And can provide certain spacing effect for coupling 5, further improve its joint strength with furnace body 1.
As an alternative embodiment, the inner coil 22 and the outer coil 21 can be installed in the furnace body 1, and then the two ends of the inner coil 22 and the outer coil 21 are welded to the pipe joints 5. At this time, since it is inconvenient to perform the welding process in the furnace body 1, it is necessary to draw the joints at both ends of the inner coil 22 and the outer coil 21 by a certain length by using the elasticity of the two joints and weld the two joints to the two pipe joints 5, respectively. Then the pipe joints 5 are welded at the notches 11 at the two ends of the furnace body 1.
The various embodiments/implementations provided herein may be combined with each other without contradiction.
