Abstract
The utility model relates to a self supporting structure of a convection heating surface of the tail part of a boiler. The self supporting structure simplifies a system structure, improves the thermal efficiency of the boiler, and brings about reliable operation of equipment. The self supporting structure is characterized in that the structure comprises a cooling pipe inside an enclosure wall of the tail part of the boiler; the end part of the cooling pipe is lapped with a carriage arranged on an opposite boiler enclosure wall after the cooling pipe in the enclosure wall corresponding to the heating surface of the tail part of the boiler is bent toward the inside of the boiler; and empty space is formed after the bending of the cooling pipe and sealed and covered by a steel plate.
Description
(1) technical field
The utility model relates to the boiler component technical field, is specially boiler tail convection heating surface self-supporting structure.
(2) background technology
Boiler especially its afterbody of hot-water boiler is furnished with a large amount of convection heating surface 1, the supporting of convection heating surface 1 in the past mainly is to rely on the girder steel of being made up of shaped steel or steel plate 3, fixedly realizes by pipe clamp, shown in Fig. 1, Fig. 2 structure.Because girder steel 3 is arranged in the high-temperature flue, be subjected to the baking of high-temperature flue gas, for preventing girder steel 3 temperature distortions, influence rigidity, tie up refractory material and insulation material girder steel 3 outside bags, the inside cooling of ventilating, system complex.In addition,, need after girder steel 3 is heated to expand, then stay the slit, so just very easily cause boiler to leak out, reduced boiler thermal output at girder steel 3 and 2 need of furnace wall because girder steel 3 is supported on the furnace wall on both sides.
(3) summary of the invention
At the problems referred to above, the utility model provides boiler tail convection heating surface self-supporting structure, and it has simplified system architecture, has improved boiler thermal output, makes equipment reliable.
Its technical scheme is such: it is characterized in that: it comprises boiler tail bag cooling tube within the walls, described bag within the walls the cooling tube corresponding with heated surface at the end of boiler is overlapped in the bracing frame on the boiler bag wall that is positioned at its offside to its end after the boiler internal bending, form neutral gear after the described cooling tube bending, the steel plate sealing covers described neutral gear.
It is further characterized in that: described steel plate is furnished with the maintenance aperture of door.
In the said structure of the present utility model, adopt the cooling tube bending of furnace wall inside to make bracing frame, and be reserved with the expansion clearance between this cooling tube and the furnace wall, and this gap is in furnace wall, and the cooling tube that is positioned at the furnace wall outside is overlapped in inner bracing frame, has solved expansion and the sealing problem in the original structure; And the steel plate that the neutral place that forms after the bending is provided with is arranged the maintenance aperture of door, can solve the difficulty of trailing space anxiety.

(5) specific embodiment
See Fig. 3, Fig. 4, Fig. 5, Fig. 6, the utility model comprises boiler tail bag cooling tube 2 within the walls, the cooling tube 2 corresponding with heated surface at the end of boiler 3 is overlapped in bracing frame 6 on the boiler bag wall that is positioned at its offside (bracing frame 6 is that the cooling tube bending by furnace wall forms) to its end after the boiler internal bending, form neutral gear after cooling tube 2 bendings, 1 is the inside dogleg section of cooling tube 2, and steel plate 4 sealings cover neutral gears.Steel plate 4 is furnished with maintenance aperture of door 5.Arrow among Fig. 1-Fig. 6 is represented the trend of flue gas.
Claims (3)
1. boiler tail convection heating surface self-supporting structure, it is characterized in that: it comprises boiler tail bag cooling tube within the walls, described bag within the walls the cooling tube corresponding with heated surface at the end of boiler is overlapped in the bracing frame on the boiler bag wall that is positioned at its offside to its end after the boiler internal bending, form neutral gear after the described cooling tube bending, the steel plate sealing covers described neutral gear.
2. according to the described boiler tail convection heating surface of claim 1 self-supporting structure, it is characterized in that: described steel plate is furnished with the maintenance aperture of door.
