Ngā pātai me ngā whakautu mō tā mātou hua huinga whakaputa hau (1)
1. He aha te nui o te hau e pau ana i ia hāora mō te pūkaha hau i whakamahia i roto i te kaupapa?
Whakautu: I roto i te mākete keri hinu, he maha ngā huarahi tuku hau, he rerekē ngā uara wera o te wahie, ā, he nui ngā rerekētanga o te kawenga. Ko te tere kawenga o te miihini hau kei waenga i te 20% me te 80%, ā, ko te whakaputanga hiko toharite o te kaupapa katoa he tata ki te 2.6-3kwh/Nm³, ko te tikanga he 2.8kwh/Nm³;
Ina whakamahia i roto i ngā kaupapa kawenga pumau pēnei i te whakaora hau i roto i te poka wai, ko te tere kawenga kei waenga i te 60% me te 80%, ā, ko te whakaputanga hiko toharite i te wā e whakahaerehia ana te kaupapa he tata ki te 3.2-3.3 kWh/Nm³; Mena ko te kawenga toharite o te kiritaki he 1000kW, ko te kai hau ia haora he 1000/3.3=300Nm³/h;
2. He aha te take kāore e taea ai e te miihini hau te mahi i te Pūkaha hau 250kW mō te wā roa? He aha te mana whakahaere tonu e taunakitia ana, ā, he aha ai?
Whakautu: Ko te kaha kawenga mōrahi o te miihini hau he 250kW, ā, ka whakahaerehia hoki te whakamātautau wheketere i runga i te mana hiko 250kW. Ko te awhe mana whakahaere tonu o te miihini hau he 60% -80%, arā, 150kW-200kW. I raro i tēnei awhe āhua mahi, ko te miihini hau te mea tino pono, me te whakaaro anō hoki ki te penapena wahie me te pai o te whakaputa hiko. Mena he teitei te kaha kawenga o te miihini hau ina whakahaerehia i te 250kW mō te wā roa, ka tino poto te wā mō ngā whakatikatika waenga me te nui o te miihini hau. Ka tūtohu atu ki ngā kaihoko kia whakamahia i raro i ngā āhuatanga kawenga tino pai.
3. I raro i ngā āhuatanga whakahaere aha ka mahi ai te Pūkaha hau 500kw te whakarite kia pai rawa te mahi?
Whakautu: Ko te pūwāhi mahi tino pai mō te miihini hiko hau kei te 70% -80% te pūwāhi kawenga. I te pūwāhi kawenga o te 70% -100%, he rite tonu te pai o te mahi ā-ringa (whakaahuatanga ngaio: te pai o te wera o te miihini), ā, ko te miihini hiko te mea tino pai o te whakaputa hiko i te pūwāhi kawenga o te 70% -80%. Nō reira, ko te pūwāhi mahi tino pai ko te 70% -80% te kawenga. Ko te whakaputa hiko hau maori paerewa mō ia mita pūtoru i tēnei pūwāhi mahi kei runga ake i te 3.4 kWh, ā, mā te whakamahi i te miihini 300kW ka puta he 3.6 kWh.
