Abstract
The invention relates to a self-supporting structure of a convection heating surface of a tail of a boiler, which simplifies a system structure, improves the thermal efficiency of the boiler and makes equipment run reliably. The self-supporting structure comprises a cooling pipe in an enclosure wall of the tail of the boiler, and a support frame positioned on an opposite enclosure wall of the boiler, wherein the cooling pipe in the enclosure wall corresponding to the heating surface of the tail of the boiler is bent towards the inside of the boiler and overlapped with the support frame; and the cooling pipe is bent to form an empty space, and a steel plate hermetically covers the empty space.
Description
(1) technical field
The present invention relates to the boiler component technical field, be specially a kind of 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 through pipe clamp, shown in Fig. 1, Fig. 2 structure.Because girder steel 3 is arranged in the high-temperature flue, receive the baking of high-temperature flue gas, for preventing girder steel 3 temperature distortions, influence rigidity, tie up refractory material and insulation material in girder steel 3 external packets, 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
To the problems referred to above, the invention provides boiler tail convection heating surface self-supporting structure, it has simplified system architecture, has improved boiler thermal output, makes equipment reliable.
Its technical scheme is such: it comprises boiler tail bag cooling tube within the walls; Said 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 said cooling tube bending, the steel plate sealing covers said neutral gear.
It is further characterized in that: said steel plate is furnished with the maintenance aperture of door; Support frame as described above is to be formed by the cooling tube bending in the furnace wall.
In the said structure of the present invention; Adopt the inner cooling tube bending of furnace wall 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; Be overlapped in inner bracing frame and be positioned at the outside cooling tube of furnace wall, 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 nervous difficulty of trailing space.

(5) specific embodiment
See Fig. 3, Fig. 4, Fig. 5, Fig. 6; The present invention includes boiler tail bag cooling tube 2 within the walls; Be 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 with heated surface at the end of boiler 3 corresponding cooling tubes 2; 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 comprises boiler tail bag cooling tube within the walls; Said 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 said cooling tube bending, the steel plate sealing covers said neutral gear.
2. according to the said a kind of boiler tail convection heating surface self-supporting structure of claim 1, it is characterized in that: said steel plate is furnished with the maintenance aperture of door.
3. according to the said a kind of boiler tail convection heating surface self-supporting structure of claim 1, it is characterized in that: support frame as described above is to be formed by the cooling tube bending in the furnace wall.
