The hanging pipe is connected with the bearing steel plate in a welding mode.
The bearing steel plate is connected with the integral steel plate in a welding mode.
Seven first open holes are formed in the integral steel plate.
And two second open holes are formed in the integral steel plate.
The invention has the beneficial effects that:
in the invention, the smoke temperature at the lower part of the tube panel is higher, and the bearing capacity of the steel plate is reduced, so that different types of first openings and second openings are arranged in the vertical direction of the integral steel plate, the first openings are positioned at the upper ends of the second openings, the first openings can be penetrated by four coiled tubes in the coiled tube panel, and the second openings can be penetrated by two coiled tubes in the coiled tube panel, so that the bearing capacity of the steel plate is improved, and the service life is prolonged.
The invention is suitable for tower boilers, prevents potential safety hazards in the operation process of the boilers, provides a reinforcing structure for the serpentine tube panel of the tower boiler, has a reinforcing effect on the suspension support of the serpentine tube panel of the heating surface, and does not influence the overall safety of the boiler even if a small supporting plate of a part of the suspension tubes of the tower boiler falls off in the operation process.
