In ddition, tis metod provides lo initil cost nd reltively lo implementtion costs. Witin tis context, seeking for lterntive to improve te efficiency of tese cycles is extremely importnt, not only in n economic point of vie, reducing te fuel consumption, but lso in n mbient-friendly prt, reducing te emission of pollutnts to te tmospere.

2 Sntos, et l. Anlysis of Combined Bryton/Rnkine structure into more complex structures in te form of dendritic cnnels, it te tree sped configurtion being tendency of evolution for tose systems. Cn Gülen e Rub W. Smit (2009) described simple, but very precise metod, to estimte o muc poer cn be extrcted from loer Rnkine cycle given n exergy output by gs turbine (iger Bryton cycle). Te metod is bsed in te Second L of Termodynmics nd, ccording to te utors, considering te tecnicl nd economic restrictions, te model cn deliver te mximum poer tt cn be extrcted by te loer cycle to ny gs turbine by just considering te output exergy. Hbib nd Zubir (1992) exmined te performnce of regenertive/reet Rnkine poer generting plnts troug n exergetic nlysis. His results indicte tt most losses occurred in te boiler nd tt tese losses could be minimized by eting te feeding ter, reducing te irreversibility of te cycle in 18%. Akib et l. (1993) creted tree types of computer softre to clculte te termodynmic properties of orking fluids nd evlute te performnce of te combined Bryton/Rnkine cycle. Severl prmeters ere vried in order to nlyze teir effects over te performnce of te combine cycle in poer plnts. According to te utors, te numericl results ere very comptible to te dt of ctive poer plnts. Kliq nd Kusik (2004) pplied te Second L of Termodynmics in combined Bryton/Rnkine cycle it reet of te gs turbine. It s investigted te effects of pressure, temperture, number of reets nd pressure loss. It s noticed tt te combustion cmber ccounted for more tn 50% of te totl exergy loss. In ddition, te efficiency of te cycle nd te mximum output poer ere found in medium pressure nd ere improved significntly en to reet stges ere present. Hoever, for more tn to reet stges, te efficiency nd output poer did not rise significntly. Frnco nd Csros (2004) evluted te fesibility of ig efficiency combined cycles. Te results soed tt it is possible to obtin poer plnts it efficiency iger tn 62%. In order to do tt, it ould be necessry to mke pproprite use of te existing tecnologies, itout te need of iting for ne tecnologicl development of turbines. Albdodim et l. (2004) investigted te performnce of big cycle composed of Bryton, to reverse prllel Bryton nd Rnkine cycle. Te expnsion pressure reltion beteen te to reverse Bryton cycles s vried, considering vlues bove te tmosperic pressure. Results soed tt te best terml efficiencies occurred for iger expnsion pressures, recing vlues of pproximtely 54%. Zng et l. (2012) proposed regenertive Bryton combined it to reverse Bryton cycles in prllel, it te regenertion occurring before te reverse cycles. Troug te nlysis of te First L of Termodynmics, it s found tt te cycle could rec iger terml efficiency en compred to tt of common cycle, but it loer specific ork. Te optiml efficiency found for tis system s of 51.2%. Gomez et l. (2014) presented poer genertion plnt in ic closed Bryton cycled s combined in prllel it vpor Rnkine cycle, exploiting te cold exergy vilble due to te regsifiction process of liquid nturl gs. Te cold exergy s used to bring te elium used in te Bryton cycle to cryogenic tempertures in te compressor entrnce nd to generte electricl poer troug direct expnsion. Energetic nd exergetic nlysis soed tt it is possible to obtin ig poer efficiency in te poer plnt, given te rigt conditions. Considering tis necessity of more efficient usge of te vilble energetic resources, tis study proposed n lterntive configurtion of et regenertors in combined Bryton/Rnkine cycle, ere regenertor in prllel is dded to te system long it second stge turbine. In order to nlyze te performnce of tis ne configurtion, termodynmic modelling nd numericl simultions ere performed for to cses: regulr Bryton/Rnkine cycle nd noter one it te proposed modifictions. At te end of te simultions, te results obtined for bot cycles re compred. COMBINED BRAYTON/RANKINE CYCLE WITH REGENERATORS IN PARALLEL In tis ork, ne configurtion for te Bryton/Rnkine cycle s proposed. Te objective s to increse te efficiency by inserting n extr regenertor nd second stge turbine, using te concept of reet for te Rnkine cycle. It s proposed tt tis extr regenertor ould be in prllel it te previous existing, s illustrted in Fig. 1. In tis cse, te ot ir output from te gs turbine (in red in Fig. 1) ould be divided in to strems t te sme temperture: te first pssing troug regenertor 1 nd being used to et te vpor input for te first stge turbine.

It is importnt to reiterte tt te pressure from points 10 nd 11 re considered te sme. By modeling te cycle it regenertors in prllel, te pressure in point 10 s cnged from 400 to 1500 kp, it intervls of 100 kp. Wit tis, te responses of te cycle for tis rnge of pressure ere obtined.

Te results son in Figure 3 revels tt, for te proposed cycle, loer mss flo rte of ir s obtined, especilly for pressure vlues round 1500 kp for point 10. Furtermore, for poer plnt ctive for more tn 20 yers, gret mount of fuel could be sved, tus te importnce of tis result s big impct economiclly. Figure 3. Vrition of te mss flo rtes of te orking fluids regrding te pressure of point 10, for te proposed cycle. By looking t Figure 3, it is possible to notice tt, s pressure p 10 increses, te mss flo rte of ir tt goes troug regenertor 1 lso incresed, ile reducing te mss flo rte tt goes troug regenertor 2. Tis result is compreensible, since s te intermedite pressure beteen te to stges turbine (p 10 ) increses, less energy is needed in te second regenertor in order to cnge te orking fluid up to te properties considered in point 11. It is possible to notice tt te exceeding energy tt did not pss troug te second regenertor is utilized minly in te first regenertor, ere mss flo rte of compressed liquid (incresing it te increse of p 10 ) s to be trnsformed into supereted vpor. Still regrding te results in Figure 3, it is seen tt te mss flo rte of vpor increses stedily it te increse of p 10. Hoever, en compred to te bencmrk cse, even for te igest vlue of p 10 studied, tis mss flo rte s reduced significntly for te ne cycle, being, t te orst cse, 14.3% loer tn te mss flo rte for te bencmrk cse. Tis reduction brings benefit of ving more compct instlltions. By nlyzing te results Figure 3, combined it Fig 4, it is seen tt te reduction of te totl mss flo rte s consequence of te reduction of te externl et given to te cycle, s expected. Tis result is son in Figure 4. If it is considered tt te rte of mixture for combustion (r nd fuel) re te sme for bot cses, tis decrese of 0.9% found for te totl ir flo nd for te et delivered to te cycle ould ccount for n equl reduction for te fuel consumption.

But, since te system efficiency incresed, tese results s lredy expected, becuse ll te et coming into te system from externl sources do so troug te iger cycle. In ddition, since te termodynmic properties of te ir ere fixed, smller mount of ir nd, tus, loer poer is generted by it. reducing te er of te vpor turbines, becuse te vpor qulity t te exit of te turbines s iger.

It is lso son in tis ork tt te usge of regenertors in prllel is good lterntive to increse te terml efficiency of poer plnts. Hoever, n exergetic nd economic nlysis ould be required to nlyze, in ider form, if te ppliction of te proposed system is dvntgeous. Tese nlyses re going to be ddressed in future orks. ACKNOWLEDGEMENTS Figure 6. Influence of pressure p 10 over te liquid poer of te turbines for te proposed cycle. It is lso noticed tt te turbines of te Rnkine cycle mde up for te poer reduction in te gs turbine. Tis is minly due to te second stge turbine, ere te poer produced incresed s te pressure level incresed. Tis result s lso expected, since by incresing p 10 it is lso reduced te energy removed from te orking fluid in te first stge turbine nd, consequently, incresed te mount of energy vilble to be extrcted by te second stge turbine. CONCLUSIONS Troug te present study, it is concluded tt te ppliction of regenertors in prllel in combined Bryton/Rnkine cycles cn ccount for severl benefits. Te min dvntge is te improvement of te cycle efficiency, ic ould reduce significntly te energy consumption, resulting in less fuel consumption ile lso reducing te pollution tt comes from te combustion of fossil fuels. In ddition, te vpor mss flo rte is reduced in 14.3%. Tis opens te possibility of ving more compct nd ceper systems, since every component in te cycle could be reduced, for given poer demnd. On te oter nd, for te sme instlltion, more poer could be extrcted from te cycle. Te utiliztion of n extr regenertor benefited te reeting process of te Rnkine cycle.
