From by reference to the accompanying drawings and the following description of being undertaken by example, can obtain more detailed understanding, wherein:
Fig. 1 is the graphical representation of exemplary of transition piece.
Fig. 2 is the graphical representation of exemplary of transition piece.
Fig. 3 is the exemplary graph of the variation of the cross-section area of diagram transition piece from the rear end to the front end;
Figure 4 shows that the non-restrictive illustrative method of implementing such as transition piece cross-section area convergence disclosed in the present specification (convergence); And

Embodiment
Fig. 1 is the graphical representation of exemplary of transition piece 100.Transition piece 100 has front end (entry end) 105 and rear end (outlet end) 110.Hot gas flows into entrance 105 and flows through the length of transition piece 100.These hot gass are discharged from transition piece 100 at outlet 110 places.
Can find out in the drawings, compare with other zones of transition piece that the temperature on the age limit zone (life limiting area) of transition piece is higher.And turbo machine whenever carries out once from starting to the circulation of stall, and these higher temperature all can cause higher range of strain.In the course of time, these strain circulations can accumulate, and reach gradually the lifetime limitation of this transition piece.These higher temperature also may cause the oxidation of transition piece material.In the course of time, this oxidation can accumulate, and reaches gradually the lifetime limitation of this transition piece.Set forth such as this specification, no matter how other parts of this transition piece are not damaged relatively, as long as when the location of this transition piece occurs significantly to damage (for example crack), just need to change whole transition piece.
In front end and rear end, there is specific corresponding cross-section area in the transition piece.Traditionally, rule rule of thumb, the front end cross-section area of transition piece is than transition piece outlet (being the rear end) large 15%.15% the rule of thumb is used on the transition piece, to reduce the recirculation (recirculation) in the transition piece.Fig. 2 is the graphical representation of exemplary of transition piece 200.Can be long-pending at 205 places intercepting entrance cross-section, at 210 places intercepting outlet cross-section area.Traditionally, the long-pending percentage decline that compares to the outlet cross-section area at 210 places of the entrance cross-section at 205 places can be followed 15% rule of thumb.Traditionally, central section 215 is before arriving 15% final rule of thumb percentage, and departing from of essence can occur its cross section.
Analyze and find, because each cross section may depart from and cause recirculation zone (recirculation zone) in the central section of transition piece, so in transition piece, can form focus (hot spot).Disclose such as this specification, if can allow the transition piece cross-section area from the front end to the rear end, reduce in constant mode, rather than with the offset manner minimizing, can reduce in fact focus.In one embodiment, if the amount of cross-section area convergence can be reduced (for example, allow the cross-section area of rear end less by 6% than front end) since 15% rule of thumb, and/or maintain at the most+/-3% tolerance limit in, just can increase life-span of transition piece.
Fig. 3 is the exemplary graph of the variation of the cross-section area of diagram transition piece from the rear end to the front end.Axle y302 represents the cross-section area of transition piece, and axle x303 represents the length of this transition piece from the rear end to the front end.The straight line of line 305 for having constant-slope, wherein cross-section area changes in constant mode along the length from the rear end to the front end.In case cross-section area and the length of rear end and front end are determined, ideal line or reference line 305 (hereinafter referred to as reference line) just can the Application standard algebraic equation etc. be determined.Curve 310 is for being in the curve outside described+/-3% scope along this transition piece length.For example, point 311 expressions are had at length 15 places by the transition piece of curve 310 representatives and are roughly 208 cross-section area, are roughly 188 cross-section area and had at length 15 places by the transition piece of reference line 305 representatives.Use above-mentioned measuring point, the point 311 in the curve 310 departs from roughly percent 10 comparing with reference line 305 equal length places.
Can be based on the cross-section area reference line of the predetermined constant variation that calculates, set up that the transition piece that is generated by computer presents (manifestation) or the transition piece of physics presents.The example that physics presents can be to follow at cross-section area to have+the physics transition piece mould of/-3% reference line that departs from.Can on the length of whole transition piece, measure the cross-section area measured value every its 1/10 length place.Also more data point can be measured more frequently to obtain, when setting up transition piece, just better result can be obtained like this.

In the embodiment at square 405 places, can determine transition piece aft end shape and rear end cross-section area.Can carry out the rear end cross-section area according to the special parameter of the nozzle (stage one nozzle, S1N) of respective stages determines.At square 410 places, can determine shape and the cross-section area of transition piece front end.The front end cross-section area can calculate according to the rear end cross-section area.At square 415 places, can determine between rear end and front end along the constant-slope of the cross-section variation of this transition piece length.At square 420 places, can set up transition piece according to the constant-slope of cross-section area, and hold it in+/-3% tolerance-level in.
Experiment finds, if can note guaranteeing cross-section area be in constant variation cross-section area reference line+/-3% scope within, just can reduce focus and can prolong working life of this transition piece.Although this specification has been discussed 15% rule of thumb for the cross-section variation of rear end and front end, in fact also can use other percentages.Experiment finds, if depart from still along the cross-section area of transition piece length be in+/-3% in, if the rule of thumb 15% can be reduced (for example, being reduced to 5%), can obtain better result working life at transition piece.Departing from more close to 0% of cross-section area, just can more not need with cross-section area from front end to after bring in and reduce, and 15% rule of thumb percentage can to tend to be 0%, still can provide splendid result simultaneously.
The technique effect of the method is that the physics that produces the transition piece in the turbine system presents (for example metal) or sets up out the reproduction (representation) that the computer of the transition piece in the turbine system generates.The test of this transition piece can be carried out with the computer standard of the physics transition piece with testing apparatus, transition piece and corresponding Computer Analysis etc.Test can be carried out for concrete transition piece design, such as the transition piece of making for one or more generator marks, and implements with physical form or digital form.Although be described as obtaining measured value at front end and rear end, it also is rational obtaining measured value in the near zone of arbitrary end.
