Iinkqubo ezincinci ze-hydro kunye nezixhobo zombane

Phambi kokuba umphunga ufike, imibhobho ejikeleze wonke umlambo yajika amanzi ibe yimisebenzi. Ezininzi zezikhephe zabo kunye nemijelo ikhona. Umbane ovela emanzini ashushu uhlala ukhona njengomthombo omkhulu wombane ovuselelekayo emhlabeni, malunga ne-15% yombane wehlabathi ngo-2023, ngakumbi ukusuka kumadam amakhulu (umbane ovela emanzini ashushu). Eli phepha lithetha ngenye intloko yesiqhelo: iinqanawa eziqhuba ngamandla ambalwa ekilowatts ukuya kumawaka amabini e-megawatts emijelo, izibuko lemigodi yakudala, imijelo yokuhambisa amanzi, kunye nemibhobho ehambisa amanzi okutya emadolophini.

Njengephepha lethu lophando lwe Fan Wall, siqala ngefizikhi, saza sajonga ukuba yintoni eyiyo inkqubo yokulinganisa kwaye yintoni iindleko zayo xa kuthelekiswa nexabiso eliqhelekileyo, ipaneli yelanga esecaleni kwesakhiwo malunga ne- $ 0.19 kwi-kWh nganye. Uhlobo olufutshane: **inkqubo encinci ye-hydro iqinisekisiwe, ihlala ixesha elide kwaye isebenza ngemini, kwaye indawo elungileyo inokubetha uphahla lwelanga ngokukhululekileyo. Kodwa amandla alula amaxesha okuhamba phantsi, amaninzi amajelo namapayi anikezela kuphela ngeekilowatts ezimbalwa, kunye neendleko ezithe nkqo zelayisensi, imisebenzi yobuqu nokhuselo lweentlanzi zihlambulule iinkqubo ezininzi ezincinci. I-in-pipe hydro ithetha kuphela apho uxinzelelo lutywinwa khona. **

Yintoni

“Izixhobo ezincinci ze-hydro” ziquka iindidi zeematshini, eziqhelekileyo zihlelwa ngobungakanani: izincinci ukuya kuthi ga kwi-10 MW, ezincinci ngaphantsi kwe-1 MW okanye i-500 kW kuxhomekeke kwilizwe, ezincinci ngaphantsi kwe-100 kW kunye ne ezincinci ngaphantsi kwe-5 ukuya kwi-10 kW (Izixhobo ezincinci ze-hydro; Izixhobo ezincinci ze-hydro). Iinkqubo ezixhaswa I-run-of-river: endaweni yendawo yokugcina amanzi, intambo yokutsala umlambo ephantsi iguqula indawo yomlambo ngemoto yokuqhuba umlambo kwaye ibuyisela umlambo ezantsi.

Imibhobho okanye intambo ye-hydro ibeka ii-turbines ngaphakathi kwezixhobo zamanzi ezikhona: amakhonkco e-amanzi ahamba phantsi komthi ukusuka kwi-reservoir, izivalve ezicima uxinzelelo phambi kokuba amanzi afike kumakhaya, imijelo yokuhambisa amanzi ngeedrops, kunye neengcambu zokusebenza konyango. Akukho manzi atsha okanye umlambo omtsha odlulayo, nto leyo eyenza ukuba i-United States isuse iiprojekthi zekhondi eziya kwi-5 MW kwilayisensi yelizwe ngo-2013.

Indlela esebenza ngayo

I-equation enye. I-hydro turbine iguqula amandla afumanekayo emvula yamanzi ibe yi-electricity. Imandla yi P = ρ × g × Q × H × η, apho ρ lizinga lokuqina kwamanzi (1,000 kg ngemitha ejikelezayo), g lizinga lokutsala (9.81 m/s²), Q ukuphuma kwamatha ejikelezayo ngomzuzwana, H intloko okanye ubude bemvula yamanzi, ngamatha, kwaye η ukusebenza kakuhle kweenjini eziqhuba amanzi, igenerator kunye nenkqubo yokuhambisa amanzi nganye nganye. Ukubeka ngokucacileyo: imitha nganye ejikelezayo iphindaphindwe kabini iwela kwimitha enye ithatha 9.81 kw. Ii-turbines ezinkulu ziguqula ngaphezulu kwe90% yazo; ezincinci zitshintsha ukusuka kwi50 ukuya kwi85% (Micro hydro).

Indawo zorhwebo lwesiphelo kunye nokuhamba. Umlambo wesixeko onemijelo encinci yokuhamba kunye ne100 m yokuhla unganika amandla afanayo njengomlambo welizwe eliphantsi enexesha elinamawaka okuhamba ngaphezulu kwe-1 m yendlela yokungena. I-turbine ilandela indawo:

• Isiqu esiphezulu, umsinga omncinci (izigidi ukuya kumawaka eemitha): Iivili zePelton neTurgo, zihlaselwa ziinqanawa zamanzi.
• Isiphelo esiphakathi: Ii-turbines zeFrancis kunye nezo zijikeleza ngokuthe tye.
• Isiqu esiphantsi, ukuphuma okuphezulu (1 ukuya kwi-10 m): Iinjini zeKaplan kunye Iziqhoboshi ze-Archimedes, ezijika ngamandla, zidlula izityalo ezilahlekileyo kwaye zilula kwintlanzi.
• Kwimibhobho: ii-turbines ezikhethekileyo ezikwilayini, okanye iipampu eziqhelekileyo zihamba ngasemva njengee-turbines, ukhetho olusetyenziswa ngokubanzi olunokusetyenziswa ngexabiso eliphantsi.

Uxinzelelo luphezulu. Kumbhobho, ubude buvela njengexinzelelo: ibar enye ilingana malunga ne-10.2 m yeκεφαλa. Le yindawo ebalulekileyo yokusetyenziswa kweenjini ze-hydro. Amadolophu agcina amanzi amaninzi ebars ezimbalwa; apho amanzi ahamba phantsi komthi ukusuka kwi-reservoir, uxinzelelo luphezulu kakhulu kumakhaya, ngoko ke ivalve ekhawulezayo ikhupha okungaphezulu ngaphandle njengeqondo lobushushu kunye nesandi. I-turbine endaweni yevalve ibuyisela. The explainer’s “valve in a water main” example, 0.3 cubic metres a second across 3 bar, is about 60 kW that is otherwise wasted.

Akukho mdla wokutya okhululekileyo kumbhobho. I-turbine ingathatha kuphela uxinzelelo olungafunekayo ezantsi komlambo. Ukubeka enye kumbhobho ofuna uxinzelelo olupheleleyo luyitshisa ngokulula kubathengi okanye yenza ipompo isebenze kanzima, ebiza kakhulu amandla angaphezu kwee-turbines. Iindawo ezilungileyo zemibhobho ziyimfuneko: intambo enkulu yoxinzelelo oluninzi, ukuphuma okukhulu kakhulu, kunye nokusetyenziswa okuzinzileyo. Iinkqubo zolawulo lwendawo yomphuhlisi omnye ziipayipi ezimalunga ne-0.6 ukuya kwi-2.4 m ububanzi, isantya sokuhamba kwe-0.9 ukuya kwi-3.7 m/s kwaye kuncinci kakhulu 5 psi (0.34 bar) yoxinzelelo olungaphezulu (Lucid Energy, archived).

Isixa sokusebenza sivela kumlambo. Imilambo inyuka kwaye ihla ngexesha lonyaka, kwaye umyalelo kufuneka ushiye amanzi aninzi emlanjeni weentlanzi kunye nezinye izinto zonke. Inkqubo encinci yomlambo ohambayo ihlala ilingana ukusetyenziswa kokuhamba okufumanekayo kwinxalenye elungileyo yonyaka; isikhephe esijikelezayo se-50 kW sisebenza nge-38% yezinto ezisebenzayo, kwaye sivala ngokwaso kwixesha elimanzi ukugcina amanzi adlula kwindlela yentlanzi.

Iimida: ezizisiseko nezokusetyenziswa

Ifizikhi. Intshukumo inamandla amakhulu kakhulu xa kuthelekiswa nokuhamba kwexesha lokuwa. A garden stream with 10 litres a second falling 5 m gives about 0.3 kW, enough for lights and a fridge but not a home’s heating. Ivalve eqhelekileyo yamanzi inika amawaka eekilowatts. Le yimilinganiselo ethembekileyo yendawo ezininzi ezincinci: iikilowatts, hayi iimegawatts.

Iindleko ezithe nkqo. Udweliso lwe-20 kW lufuna uvavanyo olufanayo, ufundo lwendalo, iimvume, ukhuseleko lwentlanzi, unxulumano lwegridi kunye nomsebenzi wezomthetho njengenkqubo ye-500 kW. Ezi zimali aziyi kuncipha ngobungakanani, ngoko ke inkqubo encinci kakhulu ihlala ibiza kakhulu nge-kWh.

Imeko-bume. Iindlela zokungena/ukuphuma kweelwandle zithintela ukufuduka kwezintaka, kwaye iinqanawa zokuqhuba zingaphazamisa iintlanzi. Nakuba nesihlalo sokuhamba ngeentlanzi, abaqhubi beqela eSettle baxela ukuba i-salmon encinci idlula phezulu komlambo kwaye bakholelwa ukuba kukho intshukumo evela kwisikhephe (Settle Hydro). Iilizwe ezininzi azifuni uvavanyo olupheleleyo lwemeko-bume yenkqubo encinci, oko kubangela ukuba izityalo zibekwe kakubi kwezinye iindawo (Izixhobo ezincinci ze-hydro). Iprojekthi elungileyo ishiya amanzi aninzi emlanjeni, idlula intlanzi zombini iindlela, kwaye ilawulwa.

Ukhuseleko lwamanzi. Ii-turbines ngaphakathi kweentambo ezinkulu zamanzi okusela ziqhatha amanzi abantu abadla ngawo. Kufuneka ziqinisekiswe ukuba zingaqhagamshelana namayeza, azivumelekanga ukuba zishiye umoya okanye izinto ezichaphazelayo ngaphakathi, kwaye kufuneka ziphele ngokukhuselekileyo, ukuze isixhobo esingasebenzisi isantya esiphezulu singayivavanya ngesantya esincinci.
