ʻO ka ikehu Geothermal kahi ʻano o ka ikehu hou e hiki ke hoʻohana i ka wela mai ka ʻāina o ka Honua e hoʻomehana i nā hale a loaʻa ka wai wela i kahi ʻano kaiaola. ʻO ia kekahi o nā kumuwaiwai hou loa i ʻike ʻole ʻia. akā kupaianaha loa kona hopena.
Kēia ikehu Pono e hoʻomohala ʻia i kahi mea kanu geothermal, akā he aha ka mea kanu wela a pehea e hana ai?
ʻO
Mea kanu uila Geothermal
ʻO kahi mea kanu mana honua he hale kahi i unuhi ʻia mai ka wela mai ka Honua e hana i ka ikehu hou. Hoʻopuka nā kalapona kalapona i ka lewa mai ka hanauna o kēia ʻano ikehu ma kahi o 45 g ma ka awelika. Kēia helu ma lalo o 5% o nā hoʻokuʻu kūlike i nā mea kanu kuni ahi, no laila hiki ke noʻonoʻo ʻia ka ikehu maʻemaʻe.
ʻO nā mea hana nui o ka ikehu geothermal i ka honua ka United States, the Philippines a me Indonesia. Pono e noʻonoʻo ʻia ʻo ka ikehu geothermal, ʻoiai e hiki ke hoʻohou hou ʻia, he ikehu palena ia. Kaupalena ʻia ia, ʻaʻole no ka mea e hoʻopau ʻia ka wela o ka Honua (mamao loa mai ia mea), akā hiki ke huki ʻia ia i kahi ala kūpono i kekahi mau wahi o ka honua kahi i ʻoi aku ai ka ikaika o ka hana terestrial thermal. Pili ia i kēlā mau "ʻāpana wela" kahi hiki ke huki ʻia ka ikehu hou aʻe no kēlā me kēia ʻāpana.
Ma muli o ka holomua ʻole o ka ʻike e pili ana i ka ikehu geothermal, kuhi ka Geothermal Energy Association ke hoʻohana wale ʻia nei i kēia manawa 6,5% o ka honua hiki o kēia ikehu.
Nā kumu waiwai ikehu Geothermal
Ma muli o ka hana ʻana o ka iwi honua ma ke ʻano he insulate layer, i mea e loaʻa ai ka ikehu geothermal, pono e hou ʻia ka honua me nā paipu, magma a wai paha. ʻAe kēia i ka hoʻokuʻu ʻana o loko a me kāna paʻa ʻana ma o nā mea kanu mana honua.
ʻO ka hanauna uila Geothermal koi i nā mahana wela hiki wale mai nā wahi hohonu o ka honua. I ʻole e lilo ka wela i ka wā o ka halihali ʻana i nā mea kanu, nā kahawai magmatic, nā wahi wai wela, kahe o ka hydrothermal, nā luawai wai a i ʻole ka hui pū ʻana o lākou āpau.
Loaʻa ka nui o nā kumuwaiwai mai kēia ʻano ikehu hoʻonui ia me ka hohonu i wili ʻia ai a me ke kokoke i nā kihi o nā pā. I kēia mau wahi ʻoi aku ka nui o ka hana geothermal, no laila ʻoi aku ka wela o ka hoʻohana.
Pehea e hana ai kahi mea kanu mana honua?
Hoʻokumu ʻia ka hana o kahi mea kanu mana honua ma muli o kahi hana paʻakikī e hana i loko ʻōnaehana kanu-kahua. ʻO ia, huki ʻia ka ikehu mai loko o ka Honua a lawe ʻia i ka mea kanu kahi e hana ai ka uila.
Kahua wela
ʻO ka māla geothermal kahi āu e hana ai e like me ka ʻāina me ka gradient geothermal kiʻekiʻe ma mua o ka maʻamau. ʻO ia, kahi hoʻonui nui aʻe o ka mahana i ka hohonu. ʻO kēia wahi me kahi gradient geothermal ʻoi aku ka kiʻekiʻe ma muli o ka loaʻa ʻana o kahi aquifer i hoʻopaʻa ʻia me ka wai wela a mālama ʻia a kaupalena ʻia e kahi papa impermeable e mālama i nā wela a me nā kaomi. ʻIke ʻia kēia ma ke ʻano he geothermal reservoir a mai aneʻi e lawe ʻia ka wela e hana i ka uila.
ʻO nā luawai hoʻoiho wela Geothermal e hoʻopili me ka mea kanu mana i loko o kēia mau māla honua. Lawe ʻia ka mahu ma o kahi pūnaewele o nā paipu a lawe ʻia i ka mea kanu kahi ua hoʻololi ʻia ka ikehu wela o ka mahu i loko o ka ikehu mīkini a laila a laila lilo i ka ikehu uila.
Kaʻina hanauna
Hoʻomaka ka hanauna hanauna me ka unuhi ʻana o ka māhu a me ka wai i hui ʻia mai ka waihona wai wai wai. Ke lawe ʻia i ka mea kanu, hoʻokaʻawale ʻia ka mahu mai ka wai geothermal e hoʻohana ana i nā pono i kapa ʻia he cyclonic separator. Ke huki ʻia ka mahu, hoʻihoʻi ʻia ka wai i ka papa i ka waihona e hoʻomehana hou (no laila he kumu hou.)
Lawe ʻia ka mahu i lawe ʻia i ka mea kanu a hoʻoheheʻe i ka turbine nona ka mea e huli ana i ka rotor ma kahi o 3 kipi i kēlā me kēia minuke, kahi e hoʻoulu ai i ka mea hana, kahi e hoʻololi ai ka hakakā me ka electromagnetic field i ka ikehu mīkini i ka ikehu uila. 13800 volts i puka mai mai ka mea hana ke hoʻololi i nā transformers, hoʻololi lākou iā 115000 volts. Hoʻokomo ʻia kēia ikehu i nā laina uila kiʻekiʻe e hoʻouna ʻia i nā hale hānai a mai laila aku i nā koena o nā hale, nā hale hana, nā kula a me nā haukapila.
Hoʻopili hou ʻia ka mokuahi geothermal a hoʻokuʻu hou ʻia i loko o ka subsoil ma hope o ka hoʻohuli ʻana i ka pōpō. Hoʻomaʻamaʻa kēia hana i ka wai i loko o ka waihona geothermal a hoʻolilo ia i mea unuhi hou i ka ikehu, no ka mea inā hana hou ʻia e lilo ia i mahu a hoʻohuli hou i ka pōpō. No kēia mau mea āpau, hiki ke ʻōlelo ʻia ka ikehu geothermal he ikehu maʻemaʻe ia, pōʻaiapuni, hou a paʻa mau, ʻoiai me ka hoʻoulu hou ʻana i ka kumuwaiwai e hoʻoulu ʻia ai ka ikehu. Inā ʻaʻole i hoʻouka hou ʻia ka wai hoʻokaʻawale a me ka mahu mahu i loko o ka waihona wai geothermal, ʻaʻole ia e manaʻo ʻia he ikehu hou ia, no ka mea, ke pau ka waiwai, ʻaʻole hiki ke hemo hou ʻia.
Nā ʻano o nā mea kanu mana geothermal
ʻEkolu ʻano o nā mea kanu mana geothermal.
Mea kanu mahu maloʻo
ʻOi aku ka maʻalahi a me ka hoʻolālā ʻana o kēia mau panela. ʻO lākou ka poʻe e hoʻohana pololei i ka māhu ma kahi mahana o ma kahi o 150 kekelē a ʻoi paha e hoʻokele i ka pōpō a e hana i ka uila.
Na Mea Pahu Uila
Hana kēia mau mea kanu i ka hoʻoulu ʻana i ka wai wela ma ke kaomi kiʻekiʻe ma o nā luawai a hoʻolauna iā ia i nā pahu wai haʻahaʻa. Ke hoʻohaʻahaʻa ʻia ke kaomi, e māhu ka ʻāpana o ka wai a hoʻokaʻawale ʻia mai ka wai e hoʻokele i ka pōpō. E like me nā manawa ʻē aʻe, hoʻihoʻi ʻia ka wai wai keu a me ka mahu mahu i ka waihona.
Nā Kikowaena Paikikala Binary
ʻO kēia ka mea hou loa a hiki ke hana i nā mahana mahana 57 kekelē wale nō. Wela wale ka wela o ka wai a hala aʻe ma ka ʻaoʻao o kekahi wai i loaʻa kahi wahi paila ma mua o ka wai. I kēia ala, ke pili i ka wai, ʻoiai ma kahi mahana o 57 kekelē wale nō, e mahu ia a hiki ke hoʻohana ʻia e neʻe i nā pōpō.
Me kēia ʻike, ʻoiaʻiʻo ʻaʻohe kānalua e pili ana i ka hana ʻana o kahi mea kanu mana honua.
Pehea e hana ai ka hoʻomehana hoʻomehana? ʻLelo mākou iā ʻoe:
