Abstract
The invention relates to the field of equipment of residual heat boilers, particularly to a support device for a residual heat boiler superheater. The support device can solve the problems that in a high temperature flue, the requirement for the selection of superheater hanger materials is high and the stress concentration occurs, and the support device can satisfy the requirements for safe operation of the superheater. The support device comprises a boiler, wherein boiler superheaters are mounted at the upper end of the boiler. The support device is characterized in that the boiler superheaters are connected with upper collecting boxes of the superheaters, upper collecting box lead-out tubes are mounted on the upper collecting boxes of the superheaters, and the upper collecting box lead-out tubes penetrate through a flue guard plate of the boiler to be communicated with a main collecting tube; rigid support devices are arranged below the main collecting tube, and the bottoms of the rigid support devices support a top steel beam of the boiler, and the upper parts of the rigid support devices are welded with a pre-welding plate; the main collecting tube is connected with the pre-welding plate in a welding manner.
Description
Technical field
The present invention relates to the apparatus field of waste heat boiler, be specially a kind of waste-heat boiler superheater bracing or strutting arrangement.
Background technology
Along with country is to the pay attention to day by day of energy-saving and emission-reduction, the Gas Turbine Generating Units application of natural gas fuel is also more and more extensive, therefore the application utilizing gas turbine institute smoke discharging to continue the waste heat boiler of UTILIZATION OF VESIDUAL HEAT IN also gets more and more, and the safe operation of waste heat boiler parts is also more and more concerned.In the waste heat boiler of configuration superheater, superheater is all be arranged in the highest region of flue-gas temperature usually, the suspension bracket of superheater is generally also arranged in exhaust gases passes, therefore also the condition of high temperature is in, require higher to the selection of suspension bracket material like this, need the material that resistance to elevated temperatures is excellent, and the connection of suspension bracket and superheater top header is for welding, this position is in the condition of high temperature and also easily produces stress concentration phenomenon, affect the safe operation of superheater, time serious, structure can be destroyed, and along with the raising of gas turbine single-machine capacity, exhaust gas temperature also increases, these problems are just more aobvious outstanding.
Summary of the invention
In order to solve the problem, the invention provides a kind of waste-heat boiler superheater bracing or strutting arrangement, the problem of stress concentration that superheater suspension bracket Material selec-tion requirement in high-temperature flue is high and occur can be solved, meet the safe operation needs of superheater.
Its technical scheme is such: a kind of waste-heat boiler superheater bracing or strutting arrangement, it comprises boiler, boiler superheater is installed in described boiler upper end, it is characterized in that, described boiler superheater connects superheater upper collecting chamber, described superheater upper collecting chamber installs header fairlead, described upper collecting chamber fairlead gathers female pipe through the flue backplate connection of described boiler, described gathering below female pipe arranges rigid support device, described rigid support bottom of device is supported in the top girder steel of described boiler, the pre-welding plate of upper weld, the described mother's pipe that gathers is welded to connect with described pre-welding plate.
It is further characterized in that, each described superheater upper collecting chamber installs two described upper collecting chamber fairleads;
Described pre-welding plate is the steel plate through stress-relieving by beat treatment;
Described rigid support device is multiple carbon steel support bars.
After adopting structure of the present invention, support due to boiler superheater gathers on female pipe outside the flue backplate of boiler, and rigid support device does not directly weld with gathering between female pipe, but be welded in and gather in the pre-welding plate of female pipe, and not in high-temperature flue gas, avoid problem of stress concentration, add reliability of structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is A place structure for amplifying schematic diagram in Fig. 1.
Detailed description of the invention
See Fig. 1, shown in Fig. 2, a kind of waste-heat boiler superheater bracing or strutting arrangement, it comprises boiler 7, three boiler superheaters 1 are installed in boiler 7 upper end, each boiler superheater 1 connects superheater upper collecting chamber 2, each superheater upper collecting chamber 2 installs two upper collecting chamber fairleads 3, upper collecting chamber fairlead 3 gathers female pipe 4 through the flue backplate 7-1 connection of boiler 7, gather below female pipe 4 and rigid support device 6 is set, rigid support device 6 bottom support, in top girder steel 7-2, the pre-welding plate 5 of upper weld of boiler 7, gathers female pipe 4 and is welded to connect with pre-welding plate 5; Pre-welding plate 5 is the steel plate through stress-relieving by beat treatment, further increases reliability of structure; Rigid support device 6 is multiple carbon steel support bars, and be in waste heat boiler outside owing to supporting, do not affect by high-temperature flue gas, material can select common carbon steel material; Overall structure is simple, and cost is low, installs also more convenient.
