[0019] The technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments.

[0020] Embodiment 1:

[0021] Reference Figures 1-4 A device for preventing the shaking of downcomer of industrial boiler, including: steel frame 6 and fixed installation on the channel steel framework 1 of steel frame 6, the side of downcomer and prewelding piece 5 is welded with connecting plate 3, and the end away from downcomer and prewelding piece 5 of connecting plate 3 is installed with arc plate 2, and the arc convex end of arc plate 2 is attached with channel steel framework 1.

[0022] Reinforcing rib 4 is further equipped between arc plate 2 and connecting plate 3.

[0023] The arc angle of arc plate 2 is 20-25 °, and specifically, 22 ° can be used.

[0024] Channel steel framework 1 and steel frame 6 are arranged in "mouth" type, so that channel steel framework 1 can protect downcomer and prewelding piece 5 around downcomer and prewelding piece 5.
