Abstract
The utility model discloses a kind of high temperature reheat machine, comprise high temperature reheater import header, high temperature reheater outlet header and be connected in the tube panel between described high temperature reheater import header and high temperature reheater outlet header.Import and outlet header adopt steel alloy to possess high temperature resistant creep rupture strength, and tube panel adopts steel alloy material to have higher decay resistance.High temperature reheater is under different load, and high temperature reheater there will not be the phenomenons such as overtemperature of tube wall, distortion.It has simple for structure, efficient, improves reheater service life, realizes the advantage of the safe and stable operation of equipment.
Description
Technical field
The utility model relates to a kind of high temperature reheat machine.
Background technology
Reheater is in fact the steam superheater that a kind of low-pressure steam making merit heats and reach uniform temperature again.From boiler superheater main steam out, steam turbine high-pressure cylinder work done, deliver in reheater and heat again to improve temperature, then send into Steam Turbine Through IP Admission and continue expansion working, be called a resuperheat circulation.The effect of reheater has further improved the thermal efficiency of power plant's circulation, and the vapor (steam) temperature of last stage vane of steam turbine is controlled in allowed limits.Along with boiler is to large capacity high parameter future development, high temperature reheater there will be the bad phenomenon such as overtemperature, distortion, causes boiler unit to occur potential safety hazard.
Utility model content
The technical problems to be solved in the utility model provides a kind of high temperature reheat machine, solves high temperature reheater in prior art and there will be the technical problems such as overtemperature, distortion.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A high temperature reheat machine, comprises high temperature reheater import header, high temperature reheater outlet header and is connected in the tube panel between described high temperature reheater import header and high temperature reheater outlet header.
Preferably, described inlet header box lumber matter adopts steel alloy.
Preferably, described outlet header material adopts steel alloy.
Preferably, the material of described tube panel is steel alloy.
Preferably, in above-mentioned high temperature reheat machine, described import header and outlet header and tube panel adopt argon arc welding technique to weld.
Preferably, in above-mentioned high temperature reheat machine, described tube panel shape of cross section is circular or oval.
The beneficial effect of high temperature reheat machine of the present utility model: import and outlet header adopt steel alloy 12Cr1MoVG alloy to possess high temperature resistant creep rupture strength, tube panel adopts steel alloy SA-213T91 material to have higher decay resistance.High temperature reheater is under different load, and high temperature reheater there will not be the phenomenons such as overtemperature of tube wall, distortion.It has simple for structure, efficient, improves reheater service life, realizes the advantage of the safe and stable operation of equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of boiler wind heater device in the utility model specific embodiment.
The specific embodiment
In use, because boiler is to large capacity high parameter future development, high temperature reheater there will be the bad phenomenon such as overtemperature, distortion to traditional boiler, causes boiler unit to occur potential safety hazard.
Technical problem to be solved in the utility model is, for above-mentioned deficiency of the prior art, to provide a kind of boiler plant exactly, solves in prior art the technical problems such as high temperature reheater overtemperature, distortion.
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is done more specifically bright.
Embodiment 1: shown in Fig. 1, the utility model comprises high temperature reheater entrance header 1, high temperature reheater outlet header 2 and is connected in the tube panel 3 between described high temperature reheater entrance header 1 and high temperature reheater outlet header 2.
Further, described inlet header box lumber matter adopts steel alloy.
Further, described outlet header material adopts steel alloy.
Further, the material of described tube panel is steel alloy.
Further, described import header and outlet header and tube panel adopt argon arc welding technique to weld.
Further, described tube panel shape of cross section is circular or oval.
In the present embodiment, this high temperature reheat machine is placed in convection pass, when this device moves, from boiler superheater main steam out steam turbine high-pressure cylinder work done, from high temperature reheater import header 1, enter this device, enter subsequently tube panel 3, the low-pressure steam in tube panel 3 by with tube panel 3 outside high-temperature flue gas carry out heat exchange, steam after heat exchange leaves this device by warm reheater outlet header 2, then sends into Steam Turbine Through IP Admission and continue expansion working.Adopt this device not only can solve high temperature reheater overtemperature, problem on deformation, and can improve internal efficiency ratio and the absolute internal efficiency of steam turbine.It has simple for structure, efficient, improves reheater service life, realizes the advantage of the safe and stable operation of equipment.
Take the above-mentioned desirable embodiment according to this patent as enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this patented technology thought, carry out various change and modification completely.The technical scope of this patent is not limited to the content on description, must determine its technical scope according to claim scope.
