Embodiment
The equipment de-sign 10 of Fig. 1 shows the known USC steaming plant with dual reheating.In steam generator or boiler 11, fresh steam produces from backwater circulation (not shown), and is directed to the first turbine 14 by main steam service 121 and main steam inlet valve 131.Turbine 14 is typically called as high pressure or HP turbine.HP turbine 14 is left by pipeline 122 in main steam path, pipeline 122 and then be branched into the first reheater reflux line 123.In the first reheater 151 of a part being substantially boiler 11, main steam stream enter service 124 and through pressure in inlet valve 132 to the first or IP turbine 161 in before by reheating.
In this stage, supply steam by reheating obtain close to or even higher than the temperature of initial fresh steam temperature.One IP turbine 161 utilizes the exotic material manufacture substantially the same with HP turbine 14.Reflux line 125 leads to the second reheater 152 from the outlet of an IP turbine 161.
In the second reheater 152, steam be again heated to close to or even higher than the temperature of initial fresh steam temperature.After passing the second reheater, steam enters into steam supply pipeline 126 and presses turbine 162 by valve 133 to the second.2nd IP turbine 162 reuses the exotic material manufacture substantially the same with an IP turbine 161 with HP turbine 14.
The steam in the outlet port of the 2nd IP turbine 162 is directed in one or more low pressure or LP turbine 163, to be finally expanded to condensing state.LP turbine 163 is configured to so-called " double fluid " turbine in an inner housing with two Bifurcation of The Equilibriums.
The single rotor axle 17 of all turbine common drive electromagnetic generators 18, as known in the art.
The equipment de-sign 10 of Fig. 2 A shows the USC steaming plant with dual reheating utilizing the re-heating subsystem of embodiment according to the present invention.Keep that there is the substantially the same component of identity function or the mark of multiple component about Fig. 1.In the design of Fig. 2 A, again there is steam generator or fresh steam boiler 11, to produce steam from backwater circulation (not shown) and to be directed to the first turbine 14 by main steam service 121 and main steam inlet valve 131.As in the example of fig. 1, turbine 14 is the high pressure or HP turbine be made up of the material of the main steam pressure P0 of the temperature and about 350bar being suitable for 700 degrees centigrade.As above, HP turbine 14 is left by pipeline 122 in main steam path, pipeline 122 and then be branched into the first reheater reflux line 123.In the first reheater 151 of a part typically being boiler 11, main steam stream enter service 124 and through pressure in inlet valve 132 to the first or IP turbine 161 in before by reheating.
In first, pressure or IP turbine 161 are separated into the first high-temperature portion 161-1 and the second low-temp. portion 161-2 in this example.When referring to separation, be meant to the first high-temperature portion 161-1 to be contained in the inner housing separated from the inner housing of the second low-temp. portion 161-2 of the inner housing with himself or by its around.When referring to when in first, pressure or IP turbine 161 are separated into the step of the first high-temperature portion 161-1 and the second low-temp. portion 161-2, therefore its most important key element is make two of turbine steps be partially received in different inner housing (having different supplies and outlet line).
In this stage, supply steam obtains the temperature of 720 degrees centigrade and the pressure of about 75bar by reheating.First high-temperature portion 161-1 of IP turbine 161 uses the exotic material manufacture substantially the same with HP turbine 14, needs lower resistance to pressure due to the vapor pressure of the reduction from the first reheat vapor cycle simultaneously.Service 128 makes the outlet of high-temperature portion 161-1 be connected to the second low-temp. portion 161-2.
Because the second low-temp. portion 161-2 of turbine 161 no longer stands the high temperature identical with first 161-1, therefore it can use the more conventional material of the construction of the steamturbine be such as applicable to for supercritical steam to build.Second low-temp. portion 161-2 of turbine 161 is shown in the double flow turbine in an inner housing with two Bifurcation of The Equilibriums.The outlet of the second low-temp. portion 161-2 is combined into the reflux line 125 steam being transmitted back to the second reheater 152.
One IP turbine 161 is separated into the first high-temperature portion 161-1 and the second low-temp. portion 161-2 has the advantage only housing and turbine portion being divided into high-temperature component and cryogenic components.Neither requiring to manufacture that there is the complete IP turbine of high-temperature component, also not needing the housing section be made up being made up of refractory alloy in side of Conventional alloys at opposite side or other turbine portion to weld together.Welding in high temperature steam environments between different-alloy is found the risk bringing crack initiation, and can be the main source of the long-term defect in USC turbine device.
In the second reheater 152, steam is heated to the temperature of 720 or 730 degrees centigrade again.After passing the second reheater, steam enters into steam supply pipeline 126 and presses turbine 162 through valve 133 to the second.The same with an IP turbine 161, the 2nd IP turbine 162 is also separated into the first high-temperature portion 162-1 and the second low-temp. portion 162-2 in this example.Separate mean the first high-temperature portion 162-1 to be contained in the inner housing separated from the inner housing of the second low-temp. portion 162-2 of the inner housing with himself or by its around.
In this stage, supply steam obtains the temperature of 720 or 730 degrees centigrade and the pressure of about 30bar by reheating.First high-temperature portion 162-1 of IP turbine 162 utilizes the exotic material manufacture substantially the same with the first high-temperature portion 161-1 with HP turbine 14, requires the resistance to pressure lower than the latter due to the vapor pressure of the reduction from the second reheat vapor cycle simultaneously.Service 129 makes the outlet of high-temperature portion 162-1 be connected to the second low-temp. portion 161-2.
Because the second low-temp. portion 162-2 of the 2nd IP turbine 162 also no longer stands the high temperature identical with first 162-1, therefore it can use the more conventional material of the construction of the steamturbine be such as applicable to for supercritical steam to build.Second low-temp. portion 162-2 of turbine 162 is shown in the double flow turbine in an inner housing with two Bifurcation of The Equilibriums.The outlet of the second low-temp. portion 161-2 is combined into and steam is sent to one or more low pressure or LP turbine 163 to be finally expanded to the service 127 of condensing state.LP turbine 163 is configured to so-called " double fluid " turbine in an inner housing with two Bifurcation of The Equilibriums.In instances, single double flow turbine 163 represents any amount of LP turbine, one in such as this turbine, two, three, four or five, depends on the gross mass flow rate of the steam through equipment.
The single rotor axle 17 of all turbine common drive electromagnetic generators 18 of Fig. 2 A, as known in the art.
The advantage obtained by the equipment implemented as shown in Figure 2 A is promoted by high-temperature turbine portion 161-1 and 162-1 is combined into double-current housing 164, and wherein, each part has its special supply and outlet conduit, as shown in the example at Fig. 2 B.In fig. 2b, keep that there is the substantially the same component of identity function or the mark of multiple component about Fig. 2 A.
Therefore, in fig. 2b, high-temperature turbine portion 161-1 and 162-1 is depicted as and is combined into double flow turbine housing 164.Steam is delivered to the first high-temperature turbine portion 161-1 of double flow turbine by service 124 from the first reheater 151, and steam is delivered to the second high-temperature turbine portion 162-1 of double flow turbine by service 126 from the second reheater 151.
The outlet of the first high-temperature turbine portion 161-1 of double flow turbine 164 is connected in first the service 128 of the low-temp. portion 161-2 pressing turbine.Press the low-temp. portion 161-2 of turbine to be double flow turbine in first, wherein, its outlet is connected to the second reheater 152 via reflux line 125.
The outlet of the second high-temperature turbine portion 162-1 of double flow turbine 164 is connected in second the service 129 of the low-temp. portion 162-2 pressing turbine.Press the low-temp. portion 162-2 of turbine to be double flow turbine in second, wherein, its outlet is combined into and steam is sent to one or more low pressure or LP turbine 163 to be finally expanded to the service 127 of condensing state.LP turbine 163 is configured to so-called " double fluid " turbine in an inner housing with two Bifurcation of The Equilibriums.In instances, single double flow turbine 163 represents any amount of LP turbine, one in such as this turbine, two, three, four or five, depends on the gross mass flow rate of the steam through equipment.
