Fig. 1 is the conceptual schematic view of the turbine part of multiplex's matter turbogenerator.It is mechanical energy with the transformation of energy with working medium that the turbine 20 of multiplex's matter turbogenerator receives working medium.As shown in the figure, first working medium is done manual work to expand in different turbine portion respectively with different workmanships position or turbine portion that second working medium is introduced into turbine 20 respectively.With reference to figure 2, it is the axial plane schematic representation of turbine simultaneously.Turbine 20 comprises the first turbine portion 20A and the second turbine portion 20B; The separatrix of the first turbine portion 20A and the second turbine portion 20B is C1-O-C2 (O is turbine 20 centers of circle); Wherein the first turbine portion 20A and the second turbine portion 20B are used for receiving respectively first working medium and second working medium; Making the turbine portion 20A that wins is mechanical energy with the transformation of energy of first working medium in fact only, and the second turbine portion 20B is a mechanical energy with the transformation of energy of second working medium in fact only.First working medium and second working medium can be handled after in turbine 20, doing manual work as required, for example are discharged or recovery etc.
It is pointed out that at this turbine 20 being divided into the first turbine portion 20A and the second turbine portion 20B is in order to show that better first working medium and second working medium are introduced into this notion that the different parts of turbine is done manual work.For this reason, be not the specific fixed position on the turbine 20 at the first turbine portion 20A and the second turbine portion 20B of this definition, and be meant the different parts of being divided by separatrix C1-O-C2 at given time.For example; In the example of Fig. 2, separatrix C1-O-C2 is a level, therefore at given time; The turbine position that rotates to horizontal separatrix C1-O-C2 top is defined as the first turbine portion 20A, and the turbine position that rotates to below the horizontal separatrix C1-O-C2 is defined as the second turbine portion 20B.
As a kind of embodiment, first working medium can comprise combustion gas, and second working medium can comprise water or steam (water possibly be in a liquid state or gaseous form in the different phase of system).Combustion gas and steam are to use two kinds of the most general working medium in the present turbogenerator.Wherein, combustion gas is the products of combustion after the fuel combustion, and fuel can be for example gasoline, rock gas, propane, diesel oil, kerosene, also can be recyclable fuel, for example E85 ethanol-gasoline, biodiesel and biogas or the like.But the notion that the different working medium of the utility model are done manual work in the different piece of turbine is not repelled the combination of other different working medium.
When first working medium comprises products of combustion, when second working medium comprised steam, this multiplex's matter turbogenerator came down to do manual work being incorporated on the same power turbine according to the workmanship of brayton cycle and workmanship according to Rankine cycle.For existing gas-steam combined circulation, can make the structure of turbogenerator group compact more like this.Usually, the temperature that combustion gas is advanced before the turbine is high more, and its workmanship ability is just high more, and the turbogenerator thermal efficiency is also just high more.But, bigger challenge is proposed also for the temperature capacity of turbine part such as blade along with the raising of fuel gas temperature.The working medium temperature of general brayton cycle is up to more than 1000 degrees centigrade, have in addition surpass 2000 degrees centigrade, and the working medium temperature of Rankine cycle is much lower relatively, is usually less than 700 degrees centigrade.In this multiplex's matter turbogenerator; Combustion gas is done manual work in the different turbine portion of turbine with steam separately; Therefore at any one time, only some receives the high temperature of high-temperature fuel gas to turbine, and another part receives the relative low temperature of steam; And along with turbine ceaselessly rotates, that a part of turbine portion that before receives high temperature can constantly rotate to the position that receives steam and by steam cooling.Because combustion gas is done manual work separately in different turbine portion with steam, therefore,, can not reduce the high temperature of combustion gas though steam constantly cools off those turbine portion that receive gas high-temperature before, i.e. the temperature before the turbine is advanced in combustion gas.In other words, the workmanship ability of high-temperature fuel gas is not weakened because of the adding of steam.
Like Fig. 3, be a rough schematic view of turbine 20, it is that example describes with single-stage axial flow turbine.In this rough schematic view, turbine 20 is represented with cylinder, the concrete structures such as blade of the turbine that do not draw, and it for example rotates along the clockwise direction shown in the arrow.Two opposing sides 22 of cylinder 20 and 24 are represented the air inlet side 22 and deflation area 24 of turbine respectively.It is half the to suppose that the first turbine portion 20A and 20B respectively account for; Promptly the separatrix C1-O-C2 of two turbine portion (wherein O is the turbine center of circle) is divided into two halves with turbine, and then the side of separatrix C1-O-C2 for example (is for example advanced first working medium above the separatrix; Combustion gas); Opposite side, for example second working medium (for example, steam) is advanced in the below, separatrix.In other words, first working medium and second working medium air inlet separatrix on turbine 20 air inlet sides 22 is C1-O-C2.Because turbine 20 constantly rotates, the working medium of passing turbine 20 also can be driven along this clockwise direction rotates.Like this, when the working medium after doing manual work was left turbine 20, it understood with respect to advance the state overall offset several angle α on the sense of rotation of turbine 20 before the turbine.That is, first working medium after the workmanship and second working medium exhaust separatrix C1 '-O-C2 ' on turbine 20 exhaust sides 24 is with respect to air inlet separatrix C1-O-C2 deviation angle α on the sense of rotation of turbine 20.Handle first working medium and second working medium of discharging if desired respectively, then need consider this deflection angle α from turbine 20.Should be understood that Fig. 3 only illustrates the rotor portion of turbine, with this whole deflection with respect to before the turbine time when leaving turbine of explanation working medium.
Relating to parameters such as pressure and temperature, air inlet/grate flow channel design parameter, secondary speed, exhaust back pressure before this deflection angle α and the turbine.For example, pressure and temperature is high more before the turbine, and secondary speed is low more, and exhaust back pressure is low more, and this deflection angle α is just more little.Otherwise then deflection angle α is high more.This deflection angle α can also can obtain through the method for computer simulation or experiment via calculating.
Fig. 4-6 is an embodiment's the schematic representation of working medium air inlet and the exhaust passage of turbine, and it is that example is explained with single stage turbine 120, and in the stereogram of Fig. 6, is clarity, the rotating shaft of not drawing and combining with turbine.Turbine 120 comprises turbine stator (also being nozzle ring) 122 and turbine rotor 124.Stator 122 has the first guide portion 122A and the second guide portion 122B.Turbine rotor 124 has the first turbine portion 124A and the second turbine portion 124B that is divided by air inlet separatrix D1-O-D2 (wherein O is turbine 120 centers of circle).Turbogenerator is provided with the first separate working medium suction tude 126 and the second working medium suction tude 128 in turbine 120 air inlet sides.The first guide portion 122A fluid communication of the first working medium suction tude 126 and turbine stator 122; First working medium is caused the first guide portion 122A of stator 122, the first turbine portion 124A that is directed to turbine rotor 124 then via the first guide portion 122A does manual work.Therefore, the first guide portion 122A of the first working medium suction tude 126 and turbine stator 122 (particularly, being the passage between the blade of the first guide portion 122A) has formed the first working medium gas-entered passageway, and the first turbine portion 124A that first working medium is caused turbine does manual work.The second guide portion 122B fluid communication of the second working medium suction tude 128 and turbine stator 122; Second working medium has been caused the second guide portion 122B of stator 122, the second turbine portion 124B that is directed to turbine rotor 124 then via the second guide portion 122B does manual work.Therefore, the second guide portion 122B of the second working medium suction tude 128 and turbine stator 122 (particularly, being the passage between the blade of the second guide portion 122B) has formed the second working medium gas-entered passageway, two working medium is caused the second turbine portion 124B of turbine.
First working medium and second working medium are the first and second turbine portion 124A, the 124B that leaves turbine rotor 124 after the completion.If want to handle respectively first working medium and second working medium left, turbogenerator can be provided with the first separate working medium outlet pipe or passage 130 and the second working medium outlet pipe or passage 132 in turbine 120 waste side.The first working medium exhaust passage 130 and the first turbine portion 124A fluid communication go up first working medium of doing manual work in fact only to be received in the first turbine portion 124A, and the second working medium exhaust passage 132 and the second turbine portion 124B fluid communication go up second working medium of doing manual work in fact only to be received in the second turbine portion 124B.
As previously mentioned, when the working medium after doing manual work was left turbine, it understood with respect to advance the state whole certain deflection angle on the sense of rotation of turbine before the turbine.That is, exhaust separatrix the D1 '-O-D2 ' of first working medium and second working medium is with respect to the sense of rotation upper deflecting several angle of air inlet separatrix D1-O-D2 at turbine rotor 124.Therefore; The first working medium exhaust passage 130 that receives first working medium also should be with respect to air inlet separatrix D1-O-D2 deflection several angle on the sense of rotation of turbine rotor 124 with the working medium reception separatrix that the second working medium exhaust passage 132 that receives second working medium forms; Make first working medium of on the first turbine portion 124A, doing manual work in fact all get into the first working medium exhaust passage 130, and second working medium of on the second turbine portion 124B, doing manual work in fact all get into the second working medium exhaust passage 132.This deflection angle according to turbine before parametric synthesis such as pressure and temperature, air inlet/grate flow channel design parameter, secondary speed, exhaust back pressure confirm.
Fig. 7 is to use first working medium and the schematic representation of second working medium at the radial flow turbine 220 of this notion of different turbine portion workmanships with Fig. 8.Different with the axial flow turbine, radial flow turbine 220 is air inlets from the turbine circumference, exhaust vertically after working medium is done manual work.Though can there be multiple arrangement the air inlet separatrix as stated, still describe in this embodiment with the second-class example that is divided into.
First working medium and second working medium are the first and second turbine portion 224A, the 224B that leaves turbine 220 after the completion.If want to handle respectively first working medium and second working medium left, turbogenerator can be provided with the first separate working medium outlet pipe or passage 230 and the second working medium outlet pipe or passage 232 in turbine 220 waste side.The first working medium exhaust passage 230 and the first turbine portion 224A fluid communication go up first working medium of doing manual work in fact only to be received in the first turbine portion 224A, and the second working medium exhaust passage 232 and the second turbine portion 224B fluid communication go up second working medium of doing manual work in fact only to be received in the second turbine portion 224B.
As previously mentioned, when the working medium after doing manual work was left turbine, it understood with respect to advance the state whole certain deflection angle on the sense of rotation of turbine before the turbine.That is, exhaust separatrix the E1 '-O-E2 ' of first working medium and second working medium is with respect to the sense of rotation upper deflecting several angle of air inlet separatrix E1-O-E2 at turbine 220.Therefore; The first working medium exhaust passage 230 that receives first working medium also should be at the sense of rotation upper deflecting several angle of turbine 220 with the second working medium exhaust passage 232 that receives second working medium; Make first working medium of on the first turbine portion 224A, doing manual work in fact all get into the first working medium exhaust passage 230, and second working medium of on the second turbine portion 224B, doing manual work in fact all get into the second working medium exhaust passage 232.This deflection angle according to turbine before parametric synthesis such as pressure and temperature, air inlet/grate flow channel design parameter, secondary speed, exhaust back pressure confirm.
Though in above description, be to illustrate with single stage turbine, this innovation concept that in fact different working medium are done manual work at the different parts of turbine can be applied to multistage turbine equally.In present multistage turbine is used, be to use multistage axial flow formula turbine (perhaps, second level turbine is an axial-flow turbine at least) mostly, therefore illustrate with axial-flow turbine below.But should be understood that, can use the application's innovation concept for multistage radial flow turbine equally.
Fig. 9 is a kind of schematic representation of using the secondary axial-flow turbine of this innovation concept.In this example, turbine 320 comprises one-level turbine 3202 and two-stage turbine 3204.But through reading this specification, those skilled in the art should be appreciated that innovation concept described here also can be applicable in the turbine stage more than secondary.
Be graphic clear and description convenience; Among Fig. 9 each grade turbine replaces with disk; The concrete structure of turbine does not draw; One-level turbine 3202 has the first turbine portion 3202A and the second turbine portion 3202B that the separatrix is F1-O-F2 (wherein O is the turbine center of circle); And two-stage turbine 3204 has the first turbine portion 3204A and the second turbine portion 3204B that the separatrix is G1-O-G2 (wherein O is the turbine center of circle), and first working medium and second working medium were being passed through the firsts and seconds turbine at 3202,3204 o'clock, can on first and second turbine portion of correspondence, do manual work.
First turbine portion 3202A of one-level turbine 3202 and the separatrix of the second turbine portion 3202B are F1-O-F2, represent that then the one-level air inlet separatrix of first and second working medium is F1-O-F2.As previously mentioned; When the completion of on the first turbine portion 3202A, doing manual work of first working medium; And when leaving one-level turbine 3202 after second working medium is done manual work and accomplished on the second turbine portion 3202B; First working medium and second working medium can be on the whole with respect to its air inlet separatrix F1-O-F1 angle [alpha] 1 that on the turbine sense of rotation, squints, promptly the one-level exhaust separatrix F1 ' of first working medium and second working medium-O-F2 ' (being represented by dotted lines) has angle of deflection 1 with respect to one-level air inlet separatrix F1-O-F2.When first and second working medium get into two-stage turbine 3204; One-level exhaust separatrix the F1 '-O-F2 ' of its secondary air inlet separatrix G1-O-G2 when leaving one-level turbine 3202 is approximate parallel, i.e. secondary air inlet separatrix G1-O-G2 has an angle of deflection 1 with respect to one-level air inlet separatrix F1-O-F1 is also approximate.Equally; When first working medium and second working medium are done completion and are left two-stage turbine 3204 on the first and second turbine portion 3204A of two-stage turbine 3204 and 3204B; The secondary exhaust separatrix G1 ' of first and second working medium-O-G2 ' (being represented by dotted lines) has angle of deflection 2 with respect to secondary air inlet separatrix G1-O-G2; But for one-level air inlet separatrix F1-O-F2, secondary exhaust separatrix G1 '-O-G2 ' then is similar to has angle of deflection 1+ α 2.Therefore, after working medium was accomplished through doing manual work at whole turbine, its angle of yaw can be similar to the stack of the angle of yaw of regarding turbines generations at different levels as.If want to reclaim respectively first and second working medium of finally discharging from turbine, total angle of yaw should be considered.
In one embodiment, the one-level turbine can be a gas turbine of directly accepting steam and combustion gas, and it is passed to a part of power the gas compressor of turbogenerator through rotatingshaft.Do not have mechanical connection between two-stage turbine and the one-level turbine.The working medium of leaving the one-level turbine continues to do manual work on two-stage turbine, but makes two-stage turbine drive load, for example generator.
In above description, turbine is the turbine portion that is divided into two five equilibriums along diameter.But the division of turbine portion can be decided according to the concrete parameter of first working medium and second working medium.Such as, Figure 10 is the another kind of example of dividing of turbine portion.Can confirm the turbine portion division according to the ratio of first working medium and second working medium.For example, account for 25% if first working medium (for example combustion gas) accounts for 75%, the second working medium (for example steam), then turbine is divided into 3/4ths, second turbine portion that first turbine portion accounts for whole turbine by separatrix H1-O-H2 and accounts for 1/4th.
Figure 11 illustration a kind of system schematic of multiplex's matter turbogenerator.Multiplex's matter turbogenerator 400 comprise turbine 420, to turbine 420 provide combustion gas (first working medium) combustion gas gas-entered passageway 430, to turbine 420 provide steam (second working medium) steam inlet passage 432, receive the fuel gas exhaust passage 434 of the combustion gas after doing manual work, receive the steam exhaust-gas passage 436 of the steam after doing manual work from turbine 420 from turbine 420.
Combustion gas and steam are introduced into the different turbine portion of power turbine 420 respectively to do manual work in different turbine portion respectively.Turbine 420 among Figure 11 and air inlet thereof and exhaust structure 430,432,434,436 can adopt any structure or other appropriate structures of describing in the foregoing description.
Combustion gas as first working medium can be provided by firing chamber 440.Firing chamber 440 can receive from the pressurized air of gas compressor 442 with from the fuel of fuel source (figure do not show), and the fuel of reception and the air generation products of combustion that in firing chamber 440, burns is promptly as the combustion gas of first working medium.
It being led to 436 as the steam of second working medium from steam exhaust-gas in water reclamation system 444 capable of using after the workmanship is back to steam inlet passage 432 after reclaiming whole or in part and handling and continues to use as second working medium.In an illustrated embodiment, water reclamation system 444 comprises condensation device 446 and heat-exchanger rig.
It is liquid water that condensation device 444 is arranged to the vapor condensation in the steam exhaust-gas passage 436.The working method of condensation device 444 can be a natural cooling, water-cooled, and mode such as air-cooled is as long as can become liquid water with vapor condensation.
Heat-exchanger rig utilize in combustion gas and the steam exhaust-gas passage 436 in the fuel gas exhaust passage 434 steam at least one of them heat heat device condensation second working medium afterwards that is condensed.In an illustrated embodiment, heat-exchanger rig comprises first heat exchanger 448 and second heat exchanger 450.
In first heat exchanger, 448 the insides, utilize the heat energy of the steam in the steam exhaust pipe 436 to heat the device 444 condensations liquid water afterwards that is condensed, make it the temperature rising or become steam.Second heat exchanger 450 is between first heat exchanger 448 and steam inlet passage 432.Steam from first heat exchanger 448 is continued heating in second heat exchanger 450.In second heat exchanger 450, steam is heated by the high-temperature fuel gas in the fuel gas exhaust passage 434.Then, the steam that leaves second heat exchanger 450 is done manual work through steam inlet passage 432 entering turbines 420.
After the steam of heating as second working medium, generally speaking the temperature of combustion gas is also very high, and its heat that carries can further be recovered utilization, for example feeds another other fluid of heat exchanger heating etc.
In the system of Figure 11, because combustion gas is to do manual work in the different turbine portion of turbine with steam, the recycling of combustion gas and steam can be carried out separately, simplifies the recovery technology and reduction cost recovery of water or steam greatly.If combustion gas is in the same place with vapor mixing, want to reclaim steam wherein, condenser must be done very greatly and make this recovery become in fact impossible.And, can mix some acidic materials (replenishing other materials) in the combustion gas, also brought difficulty and complexity for reclaiming.In addition, because the use of this condensation device effectively reduces the turbine exhaust back pressure, therefore can significantly improve turbogenerator efficient.
In the system of Figure 11, when motor was not worked, water was stored in the reclaiming system.Therefore, when system had just started, steam was not participated in workmanship, but only utilized combustion gas to come start-up system.Afterwards, be stored in and participate in workmanship again after combustion gas that the water in these heat exchangers is discharged from is heated into steam.
Figure 12 illustration another kind of mode of execution, also can be to provide as the steam of second working medium by steam boiler independently.Figure 12 illustration the system schematic of another kind of multiplex's matter turbogenerator.Multiplex's matter turbogenerator 500 comprise turbine 520, to turbine 520 provide combustion gas (first working medium) combustion gas air inlet siphunculus 530, to turbine 520 provide steam (second working medium) steam inlet duct 532, receive the fuel gas exhaust pipe 534 of the combustion gas after doing manual work, receive the steam exhaust-gas passage 536 of the steam after doing manual work from turbine 520 from turbine 520.
Combustion gas and steam are introduced into the different turbine portion of turbine 520 respectively to do manual work in different turbine portion respectively.Any structure or other appropriate structures described before turbine 520 among Figure 12 and air inlet thereof and exhaust structure 530,532,534,536 can adopt.
In the illustrative system of Figure 12, can provide by firing chamber 540 as the combustion gas of first working medium, and can provide by steam boiler as the steam of second working medium.Equally, the combustion gas and the steam of 534 and 536 discharges can be by further recyclings through the exhaust passage.Because also be the way that adopts different working medium to do manual work in different turbine portion, the system of Figure 12 has one or more advantages in the previous embodiment equally.
In above embodiment, all be to discuss with two kinds of different working medium (being combustion gas and steam).But should be pointed out that the notion of on different turbine portion, doing manual work in the different working medium of this announcement also can be applied to the situation of two or more different working medium, on different turbine portion as long as two or more working medium is done manual work and can be reached the effect of wanting.Should be understood that if use two or more working medium, then the turbine of turbogenerator comprises the turbine portion of respective number, motor can be provided with the working medium gas-entered passageway and the exhaust passage of respective number.In addition, under the background of this paper, the working medium with same kind of different operating parameter (for example temperature) also can be considered two kinds of different working medium.For example, for combustion gas, if multiple combustion gas has different temperature, then these combustion gas (though belong to same type, promptly all being combustion gas) with different temperatures also can be considered the different working medium on the utility model meaning.Therefore, the combustion gas (perhaps steam, or other working medium) that has a different temperatures is done manual work on the different turbine portion of turbine and also should be belonged to the scope of the utility model.
In sum, this paper has introduced innovation concept and the practical application of this notion on turbogenerator that multiple working medium is done manual work in the different turbine portion of turbine.As one of plurality of advantages, because different working medium is done manual work the raising thermal efficiency thereby the advantage of different working medium can combine in different turbine portion.For the different working medium of temperature; The working medium of relatively-high temperature just acts on the part turbine position; Along with the continuous rotation of turbine, the working medium of low temperature can be cooled off the turbine portion that receives high temperature refrigerant relatively, thereby can improve turbine part life-span and reliability.Also because different working medium is to do manual work in different turbine portion, this makes that the independent recovery of different working medium becomes possibility when different working medium are discharged turbine.Particularly under water or the steam situation as a kind of working medium wherein, this cost that makes water reclaim can be cheaper, and process complexity is lower.
Notion described herein may be embodied to other form under the situation that does not depart from its spirit and characteristic.Disclosed specific embodiment should be regarded as exemplary rather than restrictive.Therefore, the scope of the utility model is by appended claim, rather than confirms according to these descriptions before.The scope that all should belong to these claims in the letter and any change in the equivalency range of claim.
