Ukutshintshela kumandla azinzileyo kubeke i-Organic Rankine Cycle (ORC) kwindawo ebonakalayo. yokwenziwa kwezinto ezintsha kubuchwephesha obucocekileyo. Esi sisombululo sivumela ukuguqulwa kobushushu obuphantsi kunye nobushushu obuphakathi kumbane., kwaye uye wanda ngokukhawuleza kumacandelo afuna ukusebenza kakuhle, ukuncitshiswa kokukhutshwa kwezinto ezikhutshwayo, kunye noqoqosho olungcono.
Ukuqonda indlela i-ORC esebenza ngayo, izicelo zayo kunye nefuthe layo kwimarike kubalulekile. Kuzo zombini iingcali zecandelo lamandla kunye nabo bajonge ukuhlala phambi kwemingeni yexesha elizayo. Apha ngezantsi, uya kuphonononga kuhlalutyo olubanzi lwemigaqo yayo, umda wokuphunyezwa kwayo, kunye nenkangeleko yokukhula kwayo kwiminyaka ezayo.
Yintoni i-Organic Rankine Cycle (ORC) kwaye isebenza njani?
El Umjikelo we-Organic Rankine (ORC) Bubuchwephesha obusebenzisa imithombo yobushushu obuphantsi okanye obuphakathi, njengobushushu benkunkuma yemizi-mveliso, amandla e-geothermal, okanye amandla obushushu belanga, ukuvelisa umbane. Ngokungafaniyo nomjikelo oqhelekileyo we-Rankine, esebenzisa umphunga wamanzi njengolwelo olusebenzayo, i-ORC isebenzisa ulwelo eziphilayo (idla ngokuba ziihydrocarbons okanye iifriji ezikhethekileyo) eziba ngumphunga kumaqondo obushushu asezantsi, ngaloo ndlela zandise uluhlu lwezicelo.
Ukusebenza kwe-ORC kubandakanya izigaba ezininzi ezibalulekileyo:
- Ngumphunga: Ulwelo lwe-organic lubamba ubushushu obuvela kumthombo we-thermal, bube ngumphunga kwaye buguquke bube ngumphunga woxinzelelo oluphezulu.
- Ulwandiso: Umphunga uqhuba i-iturbine, eyenza amandla oomatshini athi emva koko ajike abe ngumbane ngejenereyitha.
- Ubume: Emva kokwandiswa, umphunga upholile kwi-condenser, ubuyela kwimeko yolwelo.
- Ukusasazwa kwakhona: Ulwelo olujiyileyo lumpontshelwa emva kwi-evaporator, ngaloo ndlela kuvalwe umjikelo.
Ukusetyenziswa kolwelo olusebenzayo olunje nge-R245FA Yinto ephambili, ekubeni bebonisa Uzinzo oluphezulu lwe-thermal, amandla aphantsi okuphela kwe-ozone (ODP=0) y amandla aphantsi obushushu behlabathi (GWP=1030), Intoni kunciphisa impembelelo yokusingqongileyo kunye nokuphucula ukusebenza kakuhle kwenkqubo ngokubanzi.
Iimpawu eziphambili kunye neenzuzo ze-ORC
I-ORC ibalasele ngokukwazi kwayo ukuguqula ubushushu obusetyenzisiweyo okanye imithombo ehlaziyekayo ibe ngamandla ombane ngendlela esebenzayo nengenabungozi kokusingqongileyo.Izibonelelo zayo eziphawulekayo ziquka:
- Ukusebenza okuphezulu kwimithombo yobushushu obuphantsi: Ukusetyenziswa kwe-organic fluids kuvumela Khupha amandla obushushu aluncedo ebengakwazi ukuwasebenzisa umjikelo oqhelekileyo.
- Indawo esezantsi yokusingqongileyo: Ulwelo olusebenzayo olufana ne-R245FA lugcina impembelelo ephantsi yokusingqongileyo, ngaphandle kokonakalisa umaleko we-ozone kunye iGWP esezantsi kakhulu kuneefriji zemveli.
- Ukuguquguquka kunye nemodyuli: Iinkqubo ze-ORC zinako ukukala ngokulula kwaye uziqhelanise nobungakanani bezityalo ezahlukeneyo kunye neentlobo zamandla, ukusuka kufakelo oluncinci olungaphandle kwegridi ukuya kwimizi-mveliso emikhulu.
- Usetyenziso olunamacandelo amaninzi: Ukusuka ekubuyiseni ubushushu kwiinkqubo zoshishino ukuya kwisizukulwana kwi-geothermal, biomass okanye izityalo ezishushu zelanga, uluhlu lokusetyenziswa luyaqhubeka ukwandisa.
Ezi mpawu zikhetha ukubandakanywa kwazo kwimizi-mveliso, amaziko ombane kunye neeprojekthi zamandla ahlaziyekayo., inegalelo kokubini kwi inzuzo yoshishino ngokunjalo nokuthotyelwa kwemigaqo yozinzo.
Ukusetyenziswa kwecandelo le-Organic Rankine Cycle
Ukusasazwa kwe-ORC kusabela kwimfuno ekhulayo yokusebenza kakuhle kunye nokuzinza kumacandelo amaninzi.Phakathi kwezona zicelo zibalulekileyo, ezi zilandelayo zivelele:
- Ukubuyiswa kobushushu benkunkuma: Kumacandelo anjengentsimbi, iikhemikhali, isamente okanye iikhemikhali zepetroli, Ubushushu obugqithisileyo buguqulwa bube ngamandla ombane, Intoni kunciphisa ukusetyenziswa kwamandla kunye neendleko zokusebenza.
- Amandla ombane: I-ORC isebenzisa ngokufanelekileyo ubushushu be-geothermal ukuvelisa umbane ngaphandle kokukhupha, ukuba a isisombululo esifanelekileyo seendawo ezinemithombo eninzi ye-geothermal.
- Ukuveliswa kwamandla obushushu belanga: Ubushushu obubanjwe ngabaqokeleli belanga bugqithiselwa kulwelo olusebenzayo, ukwenza inguqu ethe ngqo kumbane.
- IBiomass: Iiprojekthi ezisekelwe ekutshisweni kwemithombo ye-biodegradable ukwandisa ukusebenza kwabo ngokusetyenziswa kwe-ORC, ukwenza obona bushushu buveliswayo.
- Icandelo lezothutho zaselwandle nezinzima: Izithuthi zamashishini kunye neenqanawa zidibanisa iinkqubo ze-ORC ze buyisela ubushushu kwaye ngaloo ndlela wenze ngcono ukusebenza y ukunciphisa ukukhutshwa kongcoliseko.
Iindlela zobuchwepheshe kunye nokukhula kwemarike ye-ORC
Imakethi ye-Organic Rankine Cycle ifumana olona hlumo luphawulekayo kubuchwepheshe bamandla acocekileyo..
Ngokoqikelelo lwamva nje, imarike yehlabathi enxulumene ne-ORC iya kudlula I-18.800 yezigidi zeedola ngo-2024, kunye kunye Isantya sokukhula esiqikelelwayo sonyaka (CAGR) se-15% kude kube ngo-2034. Olu tyhalo lubangelwa ikakhulu yimigaqo-nkqubo karhulumente wamandla ahlaziyekayo, inkuthazo yezoqoqosho kunye nokwaziswa okwandileyo kokusebenza kakuhle kwamandla kwihlabathi jikelele..

Uhlalutyo lweNgingqi: Ziphi izisombululo zeORC ezikhula kakhulu?
Ukusasazwa kobuchwepheshe be-ORC kuyahluka kakhulu ngokwengingqi:
- Amantla Emelika: Eyona nto kugxilwe kuyo kuphuhliso, kunye ne-United States ne-Canada ekhokela utyalo-mali kwizinto ezinokuhlaziywa kunye nokudityaniswa kweenkqubo ze-ORC zemizi-mveliso kunye ne-geothermal.
- Yurophu: IJamani, iFransi, kunye ne-Italiyane zikhokela indlela yokwamkelwa komntwana ngenxa yemithetho engqongqo kunye nenkxaso-mali, eqhuba ukukhula kwemarike kunye nokwahlukahlukana kwizicelo ezininzi zemizi-mveliso.
- Asia-Pacific: I-China, iJapan, kunye ne-Indiya zijongene nokukhula kofakelo olutsha, olukhuthazwa yimigaqo-nkqubo yoluntu kunye nentaphane yemithombo ye-geothermal kunye ne-biomass.
- ELatin America, kuMbindi Mpuma naseAfrika: Nangona kwisigaba sokuqala, ukukhula okuzinzileyo kubonwa ngenxa yokufudukela kwabantu ezidolophini kunye nesidingo sokufakelwa kombane kwiindawo ezisemaphandleni.
Abadlali abaphambili kunye namandla okhuphiswano
Imarike ye-ORC ilawulwa ziinkampani ezinkulu zamazwe ngamazwe kunye nababoneleli beteknoloji, njenge ABB, Alfa Laval, Siemens, Mitsubishi Heavy Industries, Ormat Technologies, Exergy International, Turboden okanye General Electric. Ezi nkampani zinikezela ngezixhobo ezibalulekileyo kwi-R&D, umanyano lobuchule, ukufunyanwa kunye nokuqaliswa kwemveliso entsha. ukuzinzisa ubunkokeli bayo kunye nokuqhuba inguqulelo.
Ukhuphiswano luqhuba i ukulungiswa kweendleko kunye uphuhliso lwezisombululo eziya zikhula ngokwemodyuli, ezisebenzayo neziguquguqukayo kwiimfuno ezahlukeneyo zobugcisa, ezoqoqosho okanye zokusingqongileyo. I ubungakanani kunye nesabelo semarike yabadlali abaphambili iyabavumela zibonelela ngamaxabiso akhuphisanayo kunye neenkonzo ezibanzi, ukomeleza isikhundla sayo ngokuchasene neenkampani ezincinci.
Ukwahlulwa ngamandla kunye nezicelo
Iinkqubo ze-ORC zahlulahlulwe ngokusekwe kumandla azo aphumayo kunye nokusetyenziswa:
- Ngamandla: Ziyohluka kwiiyunithi ezincinci (≤ 1Mwe) ukuya kwiinkqubo ezingaphezulu kwe 10 MW, equka yonke into ukusuka kwiiprojekthi ezikwanti okanye zasemaphandleni ukuya kwimizi-mveliso emikhulu kunye nezikhululo zokuvelisa.
- Ngesicelo: Ezona zixhaphakileyo kukubuyiswa kobushushu obuvela kwinkunkuma, i-biomass, amandla e-geothermal, amandla obushushu belanga, i-oyile negesi, kunye nokubuyiswa kwenkunkuma njengomthombo wamandla.
El icandelo le-geothermal kunye noluhlu lwamandla phakathi kwe-1 kunye ne-5 MW bonisa uqikelelo olukhulu lophuhliso kude kube ngu-2034, ngenxa ye imfuno yeeprojekthi ezinobungakanani obuphakathi kunye ukudibanisa kwiindawo ezikude okanye iinkqubo ezisasazwayo.
Imingeni kunye namathuba
Ngelixa i-ORC imele isisombululo esiqinileyo se-decarbonization kunye nokusebenza kakuhle kwamandla, isajongene nocelomngeni oluphambili.
El ixabiso lokuqala lofakelo eliphezulu Ngomnye weyona miqobo iphambili, ngakumbi kwimimandla apho ukufikelela kwinkxaso-mali kulinganiselwe. Nangona ulondolozo olusebenzayo kunye neenzuzo zokusingqongileyo zithomalalisa inkcitho kwixesha eliphakathi ukuya kwelide, Iinkampani zifuna inkxaso yemali, inkxaso-mali okanye inkuthazo yerhafu ukukhawulezisa ukwamkelwa.
Ngakolunye uhlangothi, ukungabikho kwemigaqo nemigangatho emanyeneyo iyacotha ukusasazwa okukhulu, njengoko i ukungaqiniseki kwimigaqo-nkqubo nemimiselo kunokulibazisa ukuphunyezwa kwemizi-mveliso. Ukoyisa le miqobo, ngemimiselo ecacileyo kunye nezicwangciso-nkqubo zenkxaso yeziko, kuya kuba yimfuneko. ukukhulula amandla e-ORC.
