Pūnaha Whakamatao hei Arotau i ngā Whare Hiko Pūngao Geothermal
E mōhiotia ana ngā tipu hiko waiariki (PLTP), arā, ngā tipu hiko waiariki, he pūtake pūngao whakahou pono nā te mea ka taea e rātou te mahi pumau i ngā rā katoa, i ngā rā katoa. Heoi, kei muri i ēnei painga tētahi āhuatanga hangarau e tino whakatau ana i te pai me te pono o te mahi: ko te pūnaha whakamatao. Ki te kore he whakamatao tika, ka heke te mahi a te tāpine, ka piki ake te whakamahinga pūngao āwhina, ka piki ake te mōrearea o te waikura, ā, i te mutunga, ka piki ake ngā utu whakaputa hiko. E matapakihia ana e tēnei tuhinga te tūranga o ngā pūnaha whakamatao, ō rātou momo, ngā wero whakahaere, me ngā rautaki arotau hei whakanui ake i te putanga o ngā tipu hiko waiariki.
He aha te hiranga o te pūnaha whakamatao i roto i ngā tipu hiko geothermal?
I roto i ngā tipu hiko waiariki, ka whakamahia te wai waiariki (te korohū, te tote rānei) hei huri i te tāpine. I muri i te haerenga i roto i te tāpine, me whakakōkī tere te korohū kia hoki ki te wai kia taea ai te papu me te/ranei te werohanga anō ki roto i te puna wai. Me tuku te wera ki te taiao mō tēnei tukanga whakakōkī, ā, koinei te wāhi e whai wāhi ai te pūnaha whakamatao.
He nui te pānga o te pēhanga i te putanga o te tāpine (te pēhanga whakamuri) ki te whai huatanga o te tāpine. Ko te iti o te pēhanga o te pūwhakapūngao, ko te nui ake o te hekenga o te enthalpy mamaoa i roto i te tāpine, ā, ko te teitei ake o te mana ka taea te whakaputa. Mā te kore e pai te whakamatao ka piki ake te pāmahana pūwhakapūngao, ka piki ake te pēhanga o te pūwhakapūngao, ka heke hoki te mana o te tāpine. I runga i te tauine o te tipu hiko, ko ngā rerekētanga iti o te pāmahana pūwhakapūngao ka hua ake he nui o ngā mate hiko.
Hei tāpiri, he pānga anō tō te pūnaha whakamatao ki:
1. Te whakapaunga hiko ā-roto (mana āwhina): ka pau te hiko i ngā papu tohanga, ngā pā hau o te pourewa whakamatao, me ētahi atu taputapu tautoko.
2. Pono: ko te paru, te tauine, me te waikura e pā ana ki te kounga o te wai whakamatao ka arahi pea ki te wā whakamutu mahi.
3. Te tutuki i ngā whakaritenga taiao: me tutuki ngā ture e pā ana ki te rerenga wai, te rere mai i ngā pourewa whakamatao, me te whakamahinga o ngā matū.
Ngā Mātāpono Taketake o te Whakamatao me te Whakatōtō
Ko te whāinga matua o tētahi pūnaha whakamatao ko te pupuri i te pāmahana iti rawa o te pūwhakamātao, me te whakaiti i ngā utu pūngao me ngā pānga ki te taiao. Ka whakawhiti te pūwhakamātao i te wera huna mai i te mamaoa putanga o te tāpine ki te reo whakamatao (wai, hau rānei). Ka taea te hanga i te pūnaha hei pūnaha porowhita kati, hei pūnaha porowhita tuwhera rānei, i runga i te hoahoa tāutanga me te wātea o te wai.
E rua ngā huarahi matua:
– Te whakamatao mākū (whakamatao mākū/whakamomona): ka whakamahia te wai ka mimiti ā-wāhanga kia taea ai te tango i te nui o te wera me te rahi iti ake o te taputapu.
– Whakamatao maroke: ka whakamahia te hau me te kore e mimiti te wai, he pai mō ngā wāhi he iti te wai engari he nui ake te utu, ā, he iti ake te whai hua ina teitei te pāmahana o te hau.
Mō ngā tipu hiko waiariki, ko te kōwhiringa pūnaha ka whai whakaaro ki ngā āhuatanga rauemi (te mamaoa matua, te mamaoa mura, te mamaoa rua rānei), ngā āhuatanga o te rangi, te wātea o te wai, me ngā whāinga whai hua me te utu puta noa i te roanga o te kaupapa.
Ngā Momo Pūnaha Whakamatao i roto i ngā Tipu Hiko Pūngao Ā-Wharewha
1. Pou Whakamatao Makuku
Koinei te kōwhiringa tino noa mō ngā tipu mamaoa tere me ngā tipu mamaoa maroke. Ka rere te wai whakamatao mā roto i te pūwhakamātao, ka mimiti i te wera, kātahi ka rere ki te pourewa whakamatao hei whakaheke i te pāmahana mā te mimiti me te pā ki te hau.
Te taikaha:
– Ka tino whakaiti i te pāmahana o te wai kia tata ki te pāmahana o te pūangi mākū.
– He iti te rahi o te taputapu mō te kaha nui.
– Ko te tikanga he iti ake te pēhanga whakamuri o te pūwhakamātao i te whakamatao maroke.
Te korenga:
– Me whai puna wai whakakī nā te mea ka ngaro i te mimiti, te pupuhi me te mānukanuka.
– Ngā pānga pea ki te taiao (te mamaoa wai, te rerenga, me te whakamahinga wai).
– Me whakahaere matū hei ārai i te tauine/te waikura.
2. Whakamatao Maroke (Mātātari Hau-Whakamatao / ACC)
I roto i tēnei pūnaha, ka whakakōhuatia te mamaoa mā te whakamahi i tētahi whakawhiti wera whai tara e whakamataohia ana e te hau mai i te pā hau.
Te taikaha:
– He iti rawa te wai e whakamahia ana (tata kore rawa).
– He pai mō ngā wāhi maroke, mō ngā wāhi rānei he herenga te whakamahinga wai.
Te korenga:
– He nui te pānga o te pāmahana o te hau ki te whai huatanga; i te werawera, ka heke te mahi, ka piki te pēhanga whakamuri.
– E hiahia ana ki ngā wāhi nui me ngā hanganga nunui.
– Ka whakanui ake ngā pā hau kaha-teitei i te whakapaunga hiko tāpiri.
3. Pūnaha Ranu (Whakamatao Makuku-Maroke)
Ka whakakotahi i te whakamatao mākū me te whakamatao maroke. I raro i ētahi āhuatanga (hei tauira, te wā maroke, ngā here wai rānei), ka pai ake te aratau maroke; ina hiahiatia he mahi teitei ake, ka whakahohehia te aratau mākū.
Te taikaha:
– Ngāwari: ka taea te whakataurite i te whakamahinga wai me te whai huatanga.
– Ka whakaiti i te kino o te mahi i ngā pāmahana hau teitei ki te whakataurite ki te whakamatao maroke parakore.
Te korenga:
– Te nui ake o te haumitanga me te uauatanga o ngā mahi.
– He uaua ake te whakahaere pūnaha nā te whakakotahitanga o ngā hangarau e rua.
4. Te Whakamatao mō ngā Pūnaha Hanga Rua (ORC/Kalina)
I roto i tētahi tipu hiko rua, ka whakamahanahia e te wai wera whenua tētahi wai mahi (hei tauira, te isobutane, te pentane rānei) mā roto i tētahi whakawhiti wera. I muri i te hurihanga o te tāpine, ka whakakōpikopikohia te wai mahi mā te whakamahi i tētahi pūnaha whakamatao (mākū/maroke/ranu).
Nā te iti o te pāmahana whakahaere, he tino tairongo ngā whakaputa hiko rua ki te mahi a te pūwhakapūngao. Mā te pikinga iti o te pāmahana pūwhakapūngao ka pā nui ki te putanga hiko kupenga, ka nui rawa te arotautanga o te whakamatao.
Ngā Wero Whakahaere: Te Tauine, te Waikura, me te Parahanga
Ko te whai huatanga o tētahi pūnaha whakamatao e kore e whakatauhia e te hoahoa anake, engari e ngā tikanga whakahaere me te kounga o te wai anō hoki.
1. Te whakapūtanga (te whakatakotoranga o te kirinuku)
Ka taea e ngā kohuke pēnei i te silica, te konupūmā kāponāte, ētahi atu matū rānei te taunga ki runga i ngā ngongo whakapūmau, ā, ka whakaiti i te whakawhiti wera. Nō reira, ka piki ake te pāmahana o te whakapūmau, ā, ka heke te whai huatanga. Ka tutuki te whakahaere mā te whakatikatika pH, ngā aukati, te whakahaere pupuhi, me te aroturuki i te taupū mātotoru.
2. Te waikura
Ka taea e te noho mai o te hāora rewa, te CO₂, te H₂S, te pūhaumāota, me ētahi āhuatanga pH te whakatere i te waikura. He mea nui te whiriwhiri rauemi (hei tauira, ētahi maitai kore waikura, te titanium mō ngā āhuatanga tino kino), te tiaki katote, me te whakahaere matū.
3. Te Whakakino Koiora
I roto i ngā pūnaha e whakamahi ana i te wai mata, ka taea e te tipu o ngā moroiti te whakaheke i te mahi a te whakawhiti wera. He maha ngā wā ka uru ngā kaupapa patu koiora me te tātari ki roto i te rautaki whakahaere.
4. Ka heke te mahi a te pourewa whakamatao
Ka taea e te paru o te takai, te aukati o ngā pūwero hau, te kore rānei e tino pai te mahi a te pā hau, te whakaiti i te whai huatanga o te whakamatao. Mā te arotake i ngā pou whakamatao auau me te tiaki i runga i te āhua o te hau ka ārai i te hekenga roa o te mahi.
Rautaki Arotau Pūnaha Whakamatao
Hei whakapai ake i te putanga o ngā tipu hiko waiariki, me whānui te huarahi—ehara i te mea me whakaiti noa i te pāmahana, engari me pupuri hoki kia iti te whakamahinga hiko tāpiri me ngā utu tiaki.
1. Te Arotau i te Pēhanga Whakamuri o te Condenser
Ka taea e ngā kaiwhakahaere te arotahi ki te pēhanga whakamuri tino pai i runga i ngā āhuatanga o te taiao me ngā herenga o ngā taputapu. Ka pā tika te tere rere o te wai whakamatao, te tere o te pā hau o te pourewa, me te ma o te mata whakawhiti wera ki te pēhanga whakamuri.
2. Te Whakamahinga o te Puku Tere Rerekē (VSD)
Mā te whakamahi i te VSD i runga i te pā hau whakamatao, i te ACC rānei, ka taea te whakarerekē i te mana o te pā ina hiahiatia. Ka whakaitihia te whakapaunga mana tāpiri ina kore te kawenga whakamatao e eke ki tōna taumata teitei, me te kore e whakararu i te pumau o te mahi.
3. Aroturuki me te Tātari Wā-tūturu
Mā te whakamahi i ngā pūoko mō te pāmahana tomo/putanga o te pūwero, te kawe hiko, te pH, te tere o te pupuhi, te wiri o te pā, me te rerekētanga o te pēhanga ka āwhina i te kimi wawe i ngā raruraru. Mai i ngā tātaritanga māmā ki te ako mīhini, ka taea e ngā kaiwhakahaere te matapae i te paru me te whakarite i te horoi i mua i te nui o te ngaronga hiko.
4. Te Whakahaere Wai Whakakī me te Whakaheke
Ko te mea nui ki te whai huatanga o te pūnaha mākū ko te whakahaere i ngā huringa kukū (CoC). Ka moumou wai te CoC iti rawa, engari ka nui rawa te mōrearea o te tauine. Mā te arotau i te CoC i runga i te kounga wai tāpiri me ngā herenga putunga taputapu ka pai ake te whai huatanga ōhanga me te hangarau.
5. Te Kōwhiringa o te Rauemi me te Hoahoa Tika mō te Whakawhiti Wera
Mā ngā rauemi ātete-waikura me ngā whirihoranga whakawhiti wera e whakahaere ana i te horoi ka whakaiti i ngā utu huringa ora. I roto i ngā āhuatanga wai kaha, ka whai hua te haumi ki ngā rauemi utu nui mā te whakaiti i te wā kore mahi.
6. Whakaurunga ki te Pūnaha Werohanga-anō
I roto i te maha o ngā tipu hiko waiariki, ka werowerohia anō te wai whakapūhau me te tote tote. E hono ana te pāmahana me te kounga o te whakapūhau ki te mahi a te whakapūhau. Ka taea e te whakahaere whakauru i waenga i te whakamatao, te whakapūhau, me ngā papu werowero te whakapai ake i te pumau o te puna wai me te whakaiti i ngā whakararuraru mahi.
Ngā Whakaaroaro Taiao me ngā Ture
Haunga ngā āhuatanga hangarau, me rite ngā pūnaha whakamatao ki ngā here taiao: te wātea o te wai, te rere pea, te haruru o te pā, me te whakakorenga o ngā kohuke, ngā matū rānei kei roto. I roto i te horopaki oranga tonutanga, he maha ngā kaupapa hou e whakaaro ana ki te whakamatao ranu, whakamatao maroke rānei hei whakaiti i te tapuwae wai, ahakoa ngā pānga utu me te whai hua i roto i ngā āhuatanga wera.
Te Katinga
Ko te pūnaha whakamatao te "ngakau" o tētahi tipu hiko waiariki e warewarehia ana engari he mea nui. Mā te whiriwhiri i te whirihoranga tika (māku, maroke, ranu rānei), te whakahaere i te tauine me te waikura, me te whakatinana i te arotautanga e ahu mai ana i ngā raraunga me ngā mana whakahaere hou, ka taea e ngā tipu hiko waiariki te whakaputa hiko nui ake me te iti ake o te whakapaunga pūngao tāpiri me te whakaiti i te mōrearea o te whakararuraru. Hei whakamutunga, ko te whakamatao pai ehara i te mea ko te tango noa i te wera, engari he rautaki whānui hei whakapai ake i te whai huatanga, te pono, me te pumau o ngā tipu hiko waiariki.
