Definitions
- the invention relates to a steam generator, in particular in horizontal construction, with a through-flow in a nearly horizontal heating gas from a heating medium heating gas channel.
- the heat contained in the relaxed working fluid or heating gas from the gas turbine is used to generate steam for the steam turbine.
- the heat transfer takes place in a heat recovery steam generator connected downstream of the gas turbine, in which a number of heating surfaces are usually arranged for water preheating, steam generation and steam superheating.
- the heating surfaces are connected in the water-steam cycle of the steam turbine.
- the water-steam cycle usually includes several, z. B. three, pressure levels, each pressure stage may have a Verdampferlikflache.
- the invention is therefore based on the object of specifying a steam generator of the abovementioned type, in which, with a particularly low effort and in a particularly simple design, a reliable holding of the named loads, in particular the additional loads given by the design internal pressure of the heating gas, is guaranteed.
- the heating gas channel is comprised of a number of supporting frames arranged one after the other in the direction of the heating gas, at least least two of the support frames are connected to each other via a number of horizontal discs.
- the invention is based on the consideration that the manufacturing and material-related effort for reliable dissipation of said loads can be kept particularly low, especially by the introduced via the internal pressure of the flue gas load component not as in conventional systems on individual frame elements of the heating gas channel, son - instead, be focused on the foundation.
- these support frames should be connected in the manner of a truss structure via suitably positioned horizontal disks.
- the horizontal discs are designed in the manner of horizontal struts.
- the free clamping heights can be significantly reduced, for example, to one-third, so that the vertical socket only about one-eighth (corresponding to 12.5%) the usual bending moments are charged.
- a reliable Abstut- tion can be achieved with significantly reduced material usage.
- the occurring deformations are also significantly reduced by the use of H-trusses.
- a particularly reliable initiation of the loads can be achieved by providing the truss obtained by the horizontal struts in a particularly symmetrical and evenly distributed manner for the outer surfaces of the heating gas channel.
- the horizontal discs are advantageously arranged on both sides of the Schugaskanals.
- a particularly symmetrical and thus comparatively simple and effective construction is achievable by two horizontal struts are arranged in pairs opposite each other to the heating gas channel in a particularly advantageous embodiment.
- the components forming the truss frame are designed with regard to their choice of material and dimensioning suitable that the loads and bending moments introduced via the internal pressure of the flue gas can be reliably derived with sufficient safety margin with a design based on internal pressure of the fuel gas of about 70 mbar.
- this design-related internal pressure is used as the basis for all parts of the heating gas channel, although in the exit region of the heating gas channel a comparatively lower internal pressure occurs during operation due to the resulting pressure loss of the heating gas as it flows through the heating gas channel.
- the steam generator is used as a heat recovery steam generator of a gas and steam turbine plant.
- the steam generator is advantageously one of the heating gas Gas turbine downstream.
- it is expedient to provide an additional firing behind the gas turbine for increasing the heating gas temperature.
- a truss frame is formed as a supporting structure for the Schugaskanal by connecting the support frame interconnecting horizontal discs over the with particularly low material and manufacturing costs a reliable and concentrated discharge of the resulting loads is possible ,
- the steam generator 1 according to the FIG is designed as a heat recovery steam generator and downstream of a gas turbine not shown in detail downstream.
- the steam generator 1 has an enclosing wall 2, which forms in the manner of a horizontal construction in an approximately horizontal, indicated by the arrow 4
- Wiengasraum x hot gas channel 6 for the exhaust gas from the gas turbine.
- the heating gas channel 6 a number of suitably designed and dimensioned heating surfaces for preheating, evaporation and superheating of the flow medium is arranged in each case.
- the surrounding the Edelgaskanal 6 surrounding wall 2 is constructed layered in the exemplary embodiment in the usual design, adjacent to a skin forming the sheet including adjusting a insulation provided as a dam structure is arranged, which in turn is limited to the interior of the Schugaskanals 6 out of a liner.
- the heating gas channel 6 On the inlet side, the heating gas channel 6 has a comparatively small free flow cross-section, which widens continuously in the area of a transition section 8 in the direction of the heating gas 4 up to the actual free flow cross-section of the heating gas channel 6.
- the structural design of the steam generator 1 is designed specifically for a reliable recording of the resulting loads with a particularly low manufacturing and material costs.
- the supporting structure of the steam generator 1 comprises, on the one hand, a number of vertical stubs 10 which are designed with regard to dimensioning and choice of material such that they can forward the resulting vertical loads from Schuflachenlas-, pipes and the like readily to the foundation.
- a truss support frame 12 is provided over the other resulting loads are deliberately and concentrated in the foundation derived.
- the garticianstragrahmen 12 is formed from a number of seen in Bankgasraum x successively arranged Stutzrahmen 14 which comprise the Bankgaskanal 6 respectively, and which are connected to each other via a number of horizontal discs 16.
- the horizontal discs 16 are arranged on both sides of the Schugaskanals 6 and in pairs opposite each other.
- Stutzrahmen 14 are shown, which could be provided depending on possible further design criteria of the steam generator and a larger number of support frame 14. This is useful, for example, in the case of the arrangement of an additional firing or a catalyst.
- two mutually opposite horizontal disks 16 are connected to each other by a tension rod 18 which is oriented essentially horizontally.
- tie rods 18 is just in the inlet region of the Schugaskanals 6, where in the case of operation of the steam generator 1 usually the largest internal pressure of the hot gas is applied, the given by the internal pressure loads that can be up to five times higher than the wind loads, suitably coupled and compensated for each other so that no introduction of these loads or the resulting bending moments on the truss frame 12 in the foundation is required.
- the truss frames 12 are designed in the embodiment with a base width of about 2.75 m.
- two horizontal disks 16 are provided on each side of the heating gas channel 6 for load acceptance and delivery to the truss frame 12.
- the free clamping heights of the respective side surfaces of the Edelgaskanals 6 are thus reduced with respect to the introduction of force and torque to one third compared to the full height of the Edelgaskanals 6. Since the corresponding bending moments are given according to the relationship M ⁇ Q * I 2/11, thus the respective bending moment is reduced by the correspondingly lower free clamping height of about one-eighth or 12.5% of the costs necessary for the full height of the heating gas channel 6 bending moment. This achieves a solution which can be achieved with a correspondingly lower use of material and the associated production outlay.
