Abstract
The present application and the resultant patent provide a combined cycle system with a flow of feed water therein. The combined cycle system may include a gas turbine, a steam turbine, a heat exchanger with the flow of feed water flowing therethrough, an expansion source for expanding the flow of feed water, and a supplemental power generation system positioned between the heat exchanger and the expansion source and driven by the flow of feed water.
Description
- The present application and the resultant patent relate generally to gas turbine engines and more particularly relate to a combined cycle system using one or more water turbines for supplemental power generation and/or other uses from otherwise wasted energy.
- Generally described, a combined cycle system uses a combination of a gas turbine and a steam turbine to produce electrical power or otherwise drive a load. Specifically, a gas turbine cycle may be operatively combined with a steam turbine cycle by way of a heat recovery steam generator and the like. The heat recovery steam generator is a heat exchanger that allows feed water for the steam generation process to be heated by the hot combustion gases of the gas turbine exhaust. The primary efficiency of the combined cycle system arrangement is the utilization of the otherwise “wasted” heat of the gas turbine engine exhaust. Specifically, the efficiency of the heat recovery steam generator focuses on the heat transfer between the gas turbine combustion gases (“the hot side”) and the feed water and the steam (“the cold side”). As much of the heat and pressure as possible of the gas turbine combustion gases thus may provide useful work.
- Although a combined cycle system is efficient, there are numerous types of parasitic losses involved in overall system operation. For example, high pressure water from the heat recovery steam generator may be used to heat the flow of fuel to the gas turbine engine so as to improve overall turbine performance. This high pressure water, however, generally is dumped directly to the condenser after heating the fuel without utilizing all of the pressure energy therein.
- In addition to parasitic loses, a combined cycle system also may have routine operating losses. These losses may be due to equipment design requirements, pressure budgets, and the like. For example, high pressure water in the heat recovery steam generator may be expanded across a number of valves without accomplishing useful work when flowing into a low pressure drum or elsewhere at normal operating flows and pressures.
- There is thus a desire for an improved combined cycle power plant with reduced parasitic loses and operating losses. Preferably, otherwise wasted high pressure and/or heat may provide useful work for supplemental power generation and/or other uses.
- The present application and the resultant patent thus provide a combined cycle system with a flow of feed water therein. The combined cycle system may include a gas turbine, a steam turbine, a heat exchanger with the flow of feed water flowing therethrough, an expansion source for expanding the flow of feed water, and a supplemental power generation system positioned between the heat exchanger and the expansion source and driven by the flow of feed water.
- The present application and the resultant patent further provide a heat recovery steam generator with a flow of feed water therein. The heat recovery steam generator may include an economizer, a drum, and a water turbine positioned between the economizer and the drum.
- The present application and the resultant patent further provide a combined cycle system with a flow of feed water therein. The combined cycle system may include a gas turbine, a performance heater with the flow of feed water flowing therethrough, a steam turbine with a condenser, and a water turbine positioned downstream of the performance heater and driven by the flow of feed water.
- These and other features and improvements of the present application and the resultant patent will become apparent to one of ordinary skill in the art upon review of the following detailed description when taken in conjunction with the several drawings and the appended claims.

FIG. 5 is a schematic diagram of an alternative embodiment of a combined cycle system as may be described herein. - Referring now to the drawings, in which like numerals refer to like elements throughout the several views,
FIG. 1 shows a schematic diagram of a combinedcycle system 10. The combinedcycle system 10 may include agas turbine engine 12. Thegas turbine engine 12 may include acompressor 14. Thecompressor 14 compresses an incoming flow ofair 16. Thecompressor 14 delivers the compressed flow ofair 16 to acombustor 18. Thecombustor 18 mixes the compressed flow ofair 16 with a pressurized flow offuel 20 and ignites the mixture to create a flow ofcombustion gases 22. Although only asingle combustor 18 is shown, thegas turbine engine 12 may include any number ofcombustors 18. The flow ofcombustion gases 22 is in turn delivered to aturbine 24. The flow ofcombustion gases 22 drives theturbine 24 so as to produce mechanical work. The mechanical work produced in theturbine 24 drives thecompressor 14 via ashaft 26 and anexternal load 28 such as an electrical generator and the like. Thegas turbine engine 12 may use natural gas, various types of syngas, and other types of fuels. Thegas turbine engine 12 may have different configurations and may use other types of components. - The combined
cycle system 10 also includes asteam turbine 30. Thesteam turbine 30 may include ahigh pressure section 32, anintermediate pressure section 34, and one or morelow pressure sections 36 with multiple steam admission points at different pressures. Thelow pressure section 36 may exhaust into acondenser 38. One ormultiple shafts 26 may be used herein. Other configurations and other components also may be used herein. - The combined
cycle system 10 also may include a heatrecovery steam generator 40. The heatrecovery steam generator 40 may include alow pressure section 42, anintermediate pressure section 44, and ahigh pressure section 46. Eachsection low pressure section 42 may include alow pressure drum 48 and alow pressure economizer 50. Likewise, theintermediate pressure section 44 may include anintermediate pressure drum 52 and anintermediate pressure economizer 54. - Feed water from the
condenser 38 may be fed to the heatrecovery steam generator 40 via acondensate pump 56. The flow of feed water may be expanded within thelow pressure drum 48 and then pass through thesections recovery steam generator 40 so as to exchange heat with the flow ofcombustion gases 22 from thegas turbine engine 12. The steam produced in the heatrecovery steam generator 40 then may be used to drive thesteam turbine 30. Likewise, hot, high pressure water produced in the heatrecovery steam generator 40 may be used in aperformance heater 58 to heat the incoming flow offuel 20 to thecombustor 18. The water used in theperformance heater 58 generally is dumped directly to thecondenser 38 after use. This description of the combinedcycle system 10 is for the purpose of example only. Many other components and other configurations may be used herein. -
FIG. 2 shows portions of a combinedcycle system 100 as may be described herein. Specifically, portions of a heatrecovery steam generator 110 for use with the combinedcycle system 100 are shown. The heatrecovery steam generator 110 includes alow pressure section 120 among other components. Similar to that described above, thelow pressure section 120 may include anexpansion source 130 such as alow pressure drum 135 and aheat exchanger 140 such as alow pressure economizer 145. In normal operation, the flow of feed water may be heated in thelow pressure economizer 145 and expanded in thelow pressure drum 135. Other component and other configurations may be used herein. - Instead of flowing the feed water from the
lower pressure economizer 140 directly to thelow pressure drum 130 for expansion therein as is described above, at least a portion of the flow of feed water may be directed to a supplementalpower generation system 150. As will be described in more detail below, the supplementalpower generation system 150 may include awater turbine 160. Thewater turbine 160 may be in communication with a by-pass line 170 from thelow pressure economizer 140. The flow of feed water then may flow into asplitter 180 with a first portion of the flow heading towards thewater turbine 160 via aturbine line 190 and a second portion of the flow heading towards thelow pressure drum 130 via amakeup line 200. Theturbine line 190 may include one or moreflow control valves 210 and/orinlet valves 220. Themakeup line 200 may include one or morelevel control valves 230 and alevel controller 240. After passing through thewater turbine 160, the first portion of the flow may continue to thelow pressure drum 130 via areturn line 250.Additional inlet valves 220 and the like may be used herein. Other components and other configurations may be used herein. -
FIG. 3 shows an example of thewater turbine 160. Thewater turbine 160 may be in communication with theturbine line 190 via theinlet valve 220. Thewater turbine 160 may include aninlet reducer 260. Theinlet reducer 260 may have a narrowing diameter so as to increase the pressure of the flow. Theinlet reducer 260 may lead to a turbine 270 with a number of turbine vanes therein. As the flow expands across the turbine 270, hydraulic energy from the flow is converted into mechanical energy. Specifically, the mechanical energy of the turbine 270 may drive ashaft 280 with the vanes thereon. In turn, theshaft 280 may drive aload 290. In this example, theload 290 may be aninduction generator 300 and the like. Generally described, theinduction generator 300 operates at grid frequency regardless of the rotational speed. Theinduction generator 300 thus produces supplemental power for the overallcombined cycle system 100. Alternatively, theload 290 may be any device requiring a rotational driving force. For example, theload 290 may be amechanical device 305 such as a pump, a gear, and the like. Thewater turbine 160 may be of conventional design. Other components and other configurations may be used herein. - The supplemental
power generation system 150 thus uses the pressure of the flow of feed water from thelow pressure economizer 145 to drive thewater turbine 150. The otherwise wasted pressure in the flow thus drives theinduction generator 300 to produce supplemental power or other types of useful work. Multiple supplementalpower generation systems 150 andmultiple water turbines 160 may be used herein in varying locations. -
FIG. 4 shows a further embodiment of a combinedcycle system 310 as may be described herein. In this example, a supplementalpower generation system 320 may be positioned about anintermediate pressure section 330. In addition to other components, theintermediate pressure section 330 may include theexpansion source 130 as anintermediate pressure drum 340 and theheat exchanger 140 as anintermediate pressure economizer 350. Awater turbine 360 thus may be positioned between theintermediate pressure economizer 350 and theintermediate pressure drum 340 in a manner similar to that described above. Other components and other configurations may be used herein. -
FIG. 5 shows a further embodiment of a combinedcycle system 370 as may be described herein. In this example, a supplementalpower generation system 380 may be positioned between theheat exchanger 140 as aperformance heater 390 and theexpansion source 130 as acondenser 400 and/or a condensate pump 410 (and upstream of the low pressure section 120). Specifically, awater turbine 420 may be positioned downstream of theperformance heater 390 to take advantage of the high pressure flow therein. Other components and other configurations may be used herein. - The supplemental power generation systems described herein thus utilize otherwise wasted high pressure flows so as to produce supplemental power and/or otherwise useful work in a combined cycle system. The positioning of the
water turbine 160 downstream of thelow pressure economizer 140, theintermediate pressure economizer 350, and/or theperformance pump 390 are for the purpose of example only. Thewater turbine 160 may be positioned across any pressure drop in any location so as to recover energy therein (although locations with large water flow rates and high pressures may be preferred). The supplemental power generation systems thus improve overall system efficiency and output. - It should be apparent that the foregoing relates only to certain embodiments of the present application and the resultant patent. Numerous changes and modifications may be made herein by one of ordinary skill in the art without departing from the general spirit and scope of the invention as defined by the following claims and the equivalents thereof.
