Abstract
The invention provides a self-supporting superheater tube structure which has the advantages of simple assembly and light workload and can ensure the safe operation of a boiler. The superheater tube structure comprises a superheater tube and a lower boiler drum. The superheater tube structure is characterized in that the superheater tube is formed by the superposition of alternate longitudinal and transverse single-layer serpentine tubes, a bottom support part supports the lower part of the single-layer serpentine tube of the bottommost layer, and the bottom support part is connected with the lower boiler drum by welding.
Description
Technical field
The present invention relates to the technical field of structures of Industrial Boiler, be specially self-supporting superheater tube structure.
Background technology
The form combination that the superheater structure of existing horizontal oil-burning gas-fired boiler often adopts coiled pipe and heat-resistance stainless steel to support, assembling is complicated, workload is big, also to expend the part heat-resistance stainless steel, and heat-resistance stainless steel also is difficult for other steel grade welding, cause welding stress and crackle easily, hide some dangers for for the hot operation of superheater.
Summary of the invention
At the problems referred to above, the invention provides self-supporting superheater tube structure, its assembling is simple, workload is little and the safe operation that can guarantee boiler.
Self-supporting superheater tube structure, it comprises superheater tube, lower drum, it is characterized in that: the coiled pipe that described superheater tube is specially individual layer successively vertically, laterally be formed by stacking, the described individual layer coiled pipe lower support of the bottom has bottom support, and described bottom support is welded to connect described lower drum.
It is further characterized in that: the outlet of the individual layer coiled pipe of described lower floor is welded to connect the import of the individual layer coiled pipe on its upper strata;
The arragement direction of described bottom support is perpendicular to the arragement direction of the described individual layer coiled pipe of the bottom;
Described bottom support is distributed in the both sides of the described individual layer coiled pipe of the described bottom.
After adopting structure of the present invention, the coiled pipe of individual layer is prefabricated, during assembling, only need that prefabricated coiled pipe is filled in the precalculated position and get final product, its assembling is simple, workload is little, in addition, because coiled pipe successively vertically, laterally be formed by stacking, space in the middle of its stack can make its free wxpansion under hot situation can not cause pipe group generation thermal stress in the boiler operatiopn, has guaranteed the safe operation of boiler.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to structural representation enlarged drawing sketch.
The specific embodiment
See Fig. 1, Fig. 2, it comprises superheater tube, lower drum 1, the coiled pipe 2 that superheater tube is specially individual layer successively vertically, laterally be formed by stacking, the individual layer coiled pipe lower support of the bottom has bottom support 3, bottom support 3 is welded to connect lower drum 1; The outlet of the individual layer coiled pipe of lower floor is welded to connect the import (for existing mature technology, not drawing among the figure) of the individual layer coiled pipe on its upper strata; The arragement direction of bottom support 3 is perpendicular to the arragement direction of the individual layer coiled pipe of the bottom; Bottom support 3 is distributed in the both sides of the individual layer coiled pipe 2 of the bottom.
Claims (4)
1. self-supporting superheater tube structure, it comprises superheater tube, lower drum, it is characterized in that: the coiled pipe that described superheater tube is specially individual layer successively vertically, laterally be formed by stacking, the described individual layer coiled pipe lower support of the bottom has bottom support, and described bottom support is welded to connect described lower drum.
