# Te Pakihi o te Turangawaewae o Siemens SGT400 | Ngā Turangawaewae Āwhina Āwhina 2×14.3MW me te HRSG mō te whakamahi i te hiko CCGT

## Ngā Wāhinga

Ko tēnei pakihi hiko katoa he rereke i ngā turangawaewae o Siemens SGT400 e rua, ko ngā wāhinga MW449 me MW451, i hanga i te tau 2015, ā, kia rite ki te 14.3MWₑ i raro i te āhua o te whakamātau ISO. Ko tēnei pakihi he HRSG hei whakamāhi i te hiko CCGT, ā, he whakamātautau kua whakamātauria mō ngā pūnaha hiko ahi kōhanga, ngā pūnaha hiko he ahi kōhanga, ngā pūnaha hiko āwhina āwhina, me ngā pūnaha hiko CCPP he ahi kōhanga.

Ko ia o ngā SGT400 he turangawaewae āwhina āwhina, he rereke i te whakamātautau DLE me te whakamātautau VIGV, ā, he rereke i ngā whāinga:

- Te whai hua o te whakamātau āwhina: 35.6%
- Te whāinga o te pākoki: 18.5
- Te hāngā o te hā o te turangawaewae: 529°C
- Te whakamātautau tata: i roto i ngā meneti e rima
- Te iti noa o te tāwhai: 30%
- Tautuhi ā-whakamātautau mō ngā hāngā rere kōrero
- Te whai hua o te whakamātautau hāngā rere: 80–92%

Ko te HRSG e tātari ana i te hāngā rere o te turupī e whakamātautau ana i te hāngā rere hei whakamātautau mō te whakamātautau i te hāngā rere. Ko tēnei āhua e mahi pai ana mō ngā hāngā rere o te turupī, ngā wāhi whakamātautau hāngā rere, ngā pūnaha hāngā rere o ngā whenua, ngā wāhi whakamātautau hāngā rere o te rākau, ngā wāhi whakamātautau hāngā rere o te rākau, me ngā pūnaha hāngā rere e whai ana i ngā hāngā rere, i ngā hāngā rere, me ngā hāngā rere.

## Ngā whai hua matua

### 1. Te whai hua teitei me te utu iti i te wā o te ora

Ko te SGT400 e whai ana i te whai hua teitei i te 99% me te wā roa o te whakamātautau, e whakamātautau ana i te utu iti i te wā o te ora (LCC). Ko tēnei he wāhi tino pai mō ngā turupī hāngā rere mō ngā mahi e noho ana i ngā wāhi o ngā pūnaha hāngā rere me ngā wāhi whakamātautau hāngā rere, i reira ko ngā wā kāore i whakamātautau e pa ana ki te moni.

### 2. Te whai hua teitei o te whakamātautau tata me te āhua o te motu

I tēnei turanga hāngā rākau kōhatu, he iti ngā wā e taea ai te whakamāhinga tonu, ā, he wāhi hāngā i tēnei hāngā rākau kōhatu. He pai rawa tēnei i ngā kaupapa whakamāhinga o ngā hāngā hiko, i ngā kaupapa whakamāhinga o ngā hāngā hiko, i ngā hāngā hou e whai ana i ngā hāngā hiko o te rārangi hiko e rere ana. Ka taea e ngā kaimahi te whakamāhinga o ngā wāhanga i ngā wā pūmau, ā, ka taea hoki te whakamāhinga i wāhi kē i ngā wā e hiahiatia ana, he whānui ngā whānui o te whānuitanga ki ngā hāngā hiko me ngā whare hiko.

### 3. Te whānuitanga o ngā kaiwhakamāhinga me ngā whakamāhinga iti

Ko te pūnaha whakamāhinga DLE e whakamāhinga ana i te whānuitanga o ngā kaiwhakamāhinga me ngā whakamāhinga iti o te NOx, e whakamana ana i ngā whakamāhinga taiao o te ao. Koinei te wāhi e taea ai te whakamāhinga o te SGT400 i ngā hāngā hiko o te kaiwhakamāhinga o te rākau kōhatu me ngā hāngā hiko o ngā kaiwhakamāhinga o ngā rākau kōhatu, e tautoko ana i ngā kaimahi e hiahiatia ana kia whakamana i ngā whakamāhinga iti o te hau, i te wā anō nei e mau ana i te whānuitanga o te hāngā.

### 4. Te whānuitanga o te CCGT hei whakamāhinga o te hiko

Ko te whāinga o te CCGT i tēnei wā he 55–60%, ā, he maha ngā whakamāinga i te whakamahi i te hiko. Nō reira, ko tēnei te whirinaki pai rawa atu mō ngā pūnaha hiko huihui kōhatu-hiko me ngā pūnaha hiko huihui hiko me te hiko, i rere ai te whāinga o te pūnaha katoa i te whakamāhi i ngā hiko kore e whai ana, ā, he iti ake te whakamāhi i ngā rākau.

### 5. Ngā Whakamāhi Āhua Rua: Te Whakamahi i te Hiko me ngā Pūnaha Mekanik

Ko te SGT400 he rākau e whakamāhi ana i ngā mahi hiko me ngā mahi mekanik, ā, nā reira he whāinga mā ngā kaihoko kia whakamāhi i te turupounamu hiko ki ngā hākinakina o ngā pūnaha hiko me ngā pūnaha hiko kōhatu. Ko tēnei whāinga he whāinga nui i te uara o tēnei taonga i ngā āhua rereke o ngā hākinakina.

## Te Whakamātautau Tino me ngā Tuhinga Katoa

Ko ngā rākau katoa, ngā tuhinga whakamāhi me ngā tuhinga whakamāhi, me ngā kōrero mō ngā wāhanga kāore i te whakamāhi, kua oti hei whakamātautau me te whakawhitinga. Ko tēnei pakete he rākau SGT400 a Siemens āhua rua: te Unit MW449 me te MW451, i hanga i te tau 2015, ā, ko ngā rākau e rua nei he 14.3MWₑ i raro i ngā āhua ISO o te whakamāhi kōhatu.

Kua oti tā mātou whakamātautau katoa i ngā āhuatanga katoa o te whakamātautau i ngā wāhanga. Ko ngā uara o ngā taputapu, ngā raraunga whakamāhi, te āhua o ngā pūnaha, ngā tuhinga tātaihanga, me ngā kōrero mō ngā wāhanga whakauru, kua wātea katoa, kua tika, kua oti, kāore he whakamārere. Ka tautoko mātou i ngā whakamātautau e whai mai ana, i ngā whakawhitinga pakihi, me te whakawhitinga o ngā tuhinga mō tāu hiranga turangawaewae me tāu hiranga pūnaha hiko.

## He aha te take e whiriwhiri ai i tēnei pakete mō tāu hiranga pūnaha hiko

- **He turangawaewae hiko hāngā kōpū kōpū, kua whakamātautau kē:** He rāua anō ngā wāhanga ōrite, kua whakamātautau kē, e whakarite ana i te whakamārama me te whakamārama o te whakamāhi i ngā turangawaewae hiko me ngā wāhanga turangawaewae hiko.
- **He āhua o te pūnaha e whai ana i te CCGT:** I tāwhina ki te HRSG, ko tēnei pakete i whakamahinga hei whakamāhi i ngā pūnaha hiko pūtahi, me ngā pūnaha hiko pūtahi hiko-hāngā, e whakamānu ana i te whakamāhi i ngā raraunga hiko mai i ngā huinga hiko.
- **Whakamāhinga māmā, whakamāhinga whānui:** Ko te whakamāhinga DLE dry low NOx e tautoko ana i ngā pāpātanga kōkōrā o te kōkōrā, i ngā wāhanga CHP o te kōkōrā, me ngā pāpātanga whakamāhinga kōkōrā me ngā pāpātanga hāngā i ngā whakamāhinga iti o ngā hua kino.
- **Ngā whakamātautau ā-tāpoi:** I rō ngā kōkōrā kōkōrā kua whakamāhinga, me ngā kōkōrā kōkōrā kua whakamāhinga anō, ko tēnei tārua he nui ngā whakamātautau i te utu i ngā kōkōrā hou, ā, e whakapai ake ana i te wā o te whakamātautau i ngā whakamātautau ā-hāngā.
- **Te tautoko whānui:** Ko ngā kōrero katoa, ngā tuhinga O&M, me ngā kōrero mō ngā wāhanga kāore i te whakamāhinga e tautoko ana i te whakamāhinga roa mō ngā kōkōrā me ngā pāpātanga whakamāhinga kōkōrā.

## Tātaritanga Tāhuhu me ngā Āra Whakamāhinga

I te wā e tūhono ana te rere o te SGT400 i ngā haukōpae e rua, he pai ake te tīmata tūtahi, he whānui ngā whāinga o te whakamāhi, me āta whakamātautau ngā kaihoko i ngā hāinga o te rākau o te wāhi, i te hāngā o te kaiwhakamāhi, me ngā hāngā o te hōhi kia whakamātautau ai te whakamāhi pai rawa atu. Mō ngā kaiwhakamahi e whakamāhi ana i ngā hāngā o te hōhi me ngā hāngā o te hau, ko tēnei tārua e tūhono ana pū ki ngā haukōpae o te hōhi i whakamāhi ai ngā hau o te HRSG, e hanga ana i tēnei i tēnei wāhi hōhi-hau kua whakauru kia pai ai te whakamāhi. Mō ngā hāngā iti ake o ngā wāhi maha, ko te 30% te iti iho o ngā hāngā e taea ana te whakamāhi i te wāhi iti, e tautuhi ana i te whakamāhi iti i te wāhi kia tāwhai ai te whakamāhi kia tika, kāore he whakamāhi i te tika.

## Whakamātautau

Ko tēnei pākete turupete kōpū o Siemens SGT400 he whakamātau kaha mō te whakamāhi, te whakamāhi tata, te whakamāhi o ngā rākau kōpū āwhina, me te whai hua o ngā turupete kōpū o te CCGT. I whakamātua katoa i te whakamātua i ngā kōrero katoa, ko tēnei he whakamāhi turupete kōpū kaha mō ngā kaiwhakamāhi e rapu ana i ngā taonga turupete kōpū kua whakamāhinga, i ngā taonga turupete kōpū kua whakamāhinga anō mō ngā tāpoi hāngā ake i te whenua. Ahakoa kei te whakarahi koe i tēnei pūnaha kōpū, kei te whakamāhinga i tēnei pūnaha kōpū, i tēnei pūnaha kōpū hou, ko tēnei pākete tuarua o ngā SGT400 he whakamāhi pūnaha kōpū, he whakamāhi pūnaha kōpū hāngā, hei whakamāhi mō ngā tau maha.

Whakapā mai i tātou kapa mō ngā whakamārama mātauranga, ngā kōrero whakamātua, me ngā whakawhitinga tauhokohoko mō te āhua o tēnei pākete turupete kōpū o SGT400 hei tautoko i tōu pūnaha kōpū āpōpō, i tōu pūnaha kōpū me ngā hāngā.
