Momwe Majenereta Amagwirira Ntchito mu Machitidwe Otentha Kwambiri
Mphamvu zongowonjezedwanso zakhala zofunika kwambiri padziko lonse lapansi poyesa kuchepetsa zotsatira zoyipa za kusintha kwa nyengo komanso kudalira mafuta. Gwero limodzi lodalirika la mphamvu zongowonjezedwanso ndi mphamvu ya geothermal. Mphamvu ya geothermal imachokera ku kutentha komwe kuli pansi pa Dziko Lapansi. Kuti tigwiritse ntchito mphamvu imeneyi, timagwiritsa ntchito machitidwe otchedwa geothermal systems, momwe majenereta amagwira ntchito yofunika kwambiri. Nkhaniyi ikambirana momwe majenereta amagwirira ntchito m'makina a geothermal, kuyambira kutulutsa kutentha mkati mwa Dziko Lapansi mpaka kupanga magetsi ogwiritsidwa ntchito.
Chiyambi cha Mphamvu Yotentha Kwambiri
Mphamvu ya geothermal, kapena kutentha kwa geothermal, ndi mphamvu yomwe imachokera mkati mwa Dziko Lapansi. Kutentha kumeneku kumapangidwa ndi kuwonongeka kwa zinthu zotulutsa ma radiation mkati mwa Dziko Lapansi ndi m'kati mwake, komanso ndi kutentha komwe kumatengedwa panthawi yomwe Dziko Lapansi limapangidwa. Ukadaulo womwe umagwiritsidwa ntchito pogwiritsira ntchito mphamvu imeneyi umayang'ana kwambiri kugwiritsa ntchito madzi otentha ochokera pansi pa nthaka kuti apange nthunzi, yomwe kenako imagwiritsidwa ntchito kuyendetsa majenereta a turbine ndikupanga magetsi.
Dongosolo la Kutentha kwa Dziko
Dongosolo la kutentha kwa dziko nthawi zambiri limakhala ndi zigawo zikuluzikulu zingapo: chitsime chopangira, chitsime cholowetsamo, chosinthira kutentha, turbine, jenereta, ndi njira yogawa ndi kulamulira. Kutentha kuchokera mkati mwa dziko lapansi kumatulutsidwa kudzera mu chitsime chopangira, komwe madzi otentha kapena nthunzi imakwezedwa pamwamba. Kenako nthunzi yomwe imachokera imagwiritsidwa ntchito kuyendetsa turbine yolumikizidwa ndi jenereta yamagetsi.
Momwe Majenereta Amagwirira Ntchito mu Machitidwe Otentha Kwambiri
1. Kutulutsa Kutentha Padziko Lapansi
Mu gawo loyamba, kutentha kumachotsedwa m'nthaka pobowola chitsime chopangira zinthu. Chitsimechi chimatsogolera ku malo osungiramo zinthu zomwe zili ndi nthunzi kapena madzi otentha. Kuzama kwa chitsimecho kumatha kusiyana malinga ndi malo ndi malo osungiramo zinthu zomwe zili ndi kutentha kwa nthaka, nthawi zambiri pakati pa kilomita imodzi ndi zitatu pansi pa nthaka.
2. Kusintha kwa Kutentha kukhala Mpweya
Madzi otentha, kapena chisakanizo cha madzi ndi nthunzi, amachotsedwa m'chitsimemo kenako n’kunyamulidwa kupita pamwamba kudzera m'mapaipi. Pamwamba pake, madzi amenewa amalowetsedwa mu chosinthira kutentha kapena cholekanitsa kuti alekanitse nthunzi ndi madzi. Nthunzi imeneyi ndiyo chinthu chachikulu chomwe chimapangitsa kuti turbine ya jenereta iyendetsedwe.
3. Galimoto Yoyendera Yozungulira
Nthunzi yomwe imachokera ku kusinthana kwa kutentha imapita ku turbine. Turbine ili ndi masamba angapo oyikidwa pa rotor. Nthunzi yamphamvu iyi imadutsa pamwamba pa masamba a turbine, zomwe zimapangitsa kuti turbine izizungulira. Kuyenda kozungulira kumeneku ndi gawo loyamba pakusintha mphamvu ya kutentha kukhala mphamvu yamakina.
4. Kupanga Magetsi
Turbine yozungulira imalumikizidwa ku rotor ya jenereta kudzera mu shaft. Rotor ya jenereta imazungulira pamene turbine ikuzungulira, zomwe zimapangitsa kuti mphamvu ya maginito ya rotor ipange mphamvu yamagetsi mu stator ya jenereta (gawo losasuntha la jenereta). Njirayi imadziwika kuti electromagnetic induction.
5. Njira Yowongolera ndi Kugawa
Magetsi opangidwa ndi jenereta amadutsa mu dongosolo lowongolera kuti atsimikizire kuti mphamvu ndi zabwino komanso zokhazikika zisanaperekedwe ku gridi. Dongosolo lowongolera ili limayang'anira zofunikira pakugawa magetsi, ma frequency, ndi mphamvu kwa ogula.
Mitundu ya Machitidwe a Geothermal
Pali mitundu ingapo ya machitidwe a geothermal omwe amagwiritsidwa ntchito kutengera mikhalidwe ndi zosowa zinazake, kuphatikizapo:
1. Malo Opangira Mphamvu Zamagetsi Awiri
Mu dongosololi, madzi otentha kwambiri amatenthedwa kudzera m'mapaipi ndipo kutentha kumagwiritsidwa ntchito kutenthetsa madzi ena okhala ndi kutentha kochepa, monga isobutane. Nthunzi yochokera ku madzi achiwiriwa imagwiritsidwa ntchito kuyendetsa turbine ndi jenereta.
2. Chomera Chouma Chotentha
Dongosololi limagwiritsa ntchito nthunzi mwachindunji kuchokera ku malo osungiramo zinthu zotentha kwambiri kuti liyendetse turbine. Ndi ukadaulo wakale kwambiri komanso wosavuta kwambiri wa kutentha kwambiri.
3. Jenereta ya Flash Steam
Malo opangira magetsi amenewa amagwiritsa ntchito madzi otentha pa mphamvu yapamwamba, omwe, akapangidwa pamwamba, amachepetsa mphamvu yake ndipo amasanduka nthunzi. Kenako nthunzi iyi imagwiritsidwa ntchito kuyendetsa turbine.
Ubwino ndi Mavuto
Kuposa
1. Wosamalira chilengedwe
Malo opangira magetsi ochokera ku geothermal amatulutsa mpweya woipa kwambiri wowononga kutentha kuposa malo opangira magetsi ochokera ku zinthu zakale.
2. Magwero a Mphamvu Zongowonjezedwanso
Mphamvu ya geothermal ndi gwero la mphamvu lomwe silimatha malinga ngati kutentha kwa dziko lapansi kukupitirirabe.
3. Kupezeka Kwambiri
Mosiyana ndi mphamvu ya dzuwa kapena mphepo, mphamvu ya geothermal imapezeka nthawi zonse ndipo sizidalira nyengo.
Chovuta
1. Ndalama Zoyambira Zapamwamba
Ndalama zoyambira zofufuzira ndi kukumba zitsime za geothermal ndi zazikulu kwambiri.
2. Zoopsa za Dziko
Malo omwe angapezeke magetsi opangira magetsi otenthetsera ndi ochepa m'madera omwe ali ndi mphamvu yotenthetsera, mwachitsanzo ku Pacific Ring of Fire.
3. Kasamalidwe ka Madzi ndi Migodi
Madzi omwe amagwiritsidwa ntchito akhoza kukhala ndi mchere womwe ungayambitse dzimbiri kapena kutayika pa zipangizo.
Mapeto
Majenereta mu machitidwe a geothermal amachita gawo lofunika kwambiri pakusintha mphamvu ya kutentha kuchokera mkati mwa dziko lapansi kukhala magetsi ogwiritsidwa ntchito. Njirayi imayamba ndi kuboola ndi kutulutsa madzi otentha, kulekanitsa nthunzi, kuyendetsa turbine, ndipo pamapeto pake kusintha mphamvu yamakina kukhala magetsi pogwiritsa ntchito jenereta. Ngakhale akukumana ndi mavuto monga mtengo wokwera woyambira komanso zoopsa za geological, ubwino wa mphamvu ya geothermal, monga kukhalitsa ndi kutsika kwa mpweya woipa, zimapangitsa kuti ikhale njira yokongola mkati mwa gulu la mphamvu zongowonjezwdwa padziko lonse lapansi.
