4. Te hoahoanga hau me te whakatakotoranga punaha
4.1 Tawhā hoahoa matua
4.1.1 Te hohonutanga o te keri. Ko te toharite ko te 4.5m, ko te hohonutanga o te ngingio he 4.0m.
4.1.2 Te nui o nga pahū. Tangohia te 1.8kg/m3mo te keri wahanga katoa, a ko te nui o te pahū mo te pupuhi kotahi he 767kg. Ko te keri o te poka pairati he 1.8kg/m3, a ko te nui o te pupuhi pupuhi he 364kg.
4.1.3 Te wa whakangao i te auahi. Ko te keri o te wahanga katoa me nga rua pairati whakarara i tangohia mo te 20 meneti.
4.1.4 Te tere o te rerenga o te hau i raro i te whenua mo ia 100 mita. Tangohia a P100=1.0%~2.0%.
4.1.5 I te wa e whakawhanuihia ana te huarahi, ko te reanga rerenga o te hau o te tatau hau he 1.5%.
4.1.6 Ko te taurangi kohi hau o te miihini diesel i roto i te kauhanga i muri i te whakaurunga o te taputapu horoi hau ko te 4.0m3/(min·kW).
4.1.7 Te teitei. Tangohia te teitei toharite o te kauhanga kia 3600m.
4.1.8 Te whakarea whakatikanga teitei o te kaha o te hau
， ka tango i te teitei toharite o te rohenga kauhanga o Guanjiao ko z=3600m, katahi
.
4.1.9 Ka mau ki te whakarea parenga waku ki te taha o te ngongo whakangao, ara, te whakarea Darcy λ= 0.012~0.015.
4.1.10 Ko te tere paerewa hoahoa o te taraka putunga he 10km/h, me te titahatanga o te 5°, ki te kore e taurite te mata o te huarahi, ko te 5km/h te tere.
4.1.11Ko te parenga hau o te urunga o te hau me te putanga o te rakau kokiri. Tangohia te nama 6 (2808m) hei tauira, i muri i te urunga mai o te rakau kokiri ki roto i te kohao matua, ka mahia te hanga i te huarahi ki te urunga me te putanga o Raina I me II, me te katoa o nga mata mahi e 4.
17.1m te waahanga whitinga o te riu kuuru o te hau i te taha o runga o te kaa.2, he 16.96m te paenga hauwhā porohita, a ko te diameter rite he 4.03m. Ko te waahi whitinga o te ngongo ngongo i te taha o raro o te kaa kokiri he 22.0m2, ko te paenga tapawhā he 19.88m, ko te diameter rite he 4.43m.
4.2 Nga Tawhā Hoahoa me te Pūnaha o te Mahinga Whakahau Ranu i te Ara Papapapa o te Ara Whakapiki.
Ko te Ripanga 4 e whakaatu ana i te hoahoa me nga tawhā o te punaha o te hau whakauru i roto i te huarahi papapaki o ia rakau kokiri. Hei tauira, i roto i te 6 inclined shaft, ka taea te whiriwhiri i te momo 125B-2110 counter-rotating axial flow fan. Ko te 1800m te rahinga hau i hangaia3/min me te tapeke pehanga 5000Pa. , Ko te mana motuka ko 2 × 110kW, me te ture tere e rua-waahi.
