I te wā e whakahaerehia ana ngā tipu hiko wera, he take nui tonu te pakaru me te haehae o ngā taputapu e pā ana ki te pai o te whakaputa me te pikinga o ngā utu tiaki. Ko ngā roera kawe whitiki me ngā paipa taka waro o te pūnaha kawe waro, tae atu ki ngā economizer me ngā superheater o te pūnaha poiha, ka pāngia e te pirau roa e ngā rauemi me te waikura pāmahana teitei, ka hua ake he tino pakaru. I ngā tau tata nei, kua whānuitia te whakamahinga o ngā taera uku alumina i roto i te mara o te ārai-kakahu i roto i ngā tipu hiko nā te mea he tino pai te mahi, ka tutuki ai ngā pānga ārai-kakahu whakamiharo, ā, ka whakatau pai i tēnei raruraru.
Ko te mahi ātete-kakahu pai rawa atu o ngā taera uku alumina i ahu mai i ō rātou āhuatanga rauemi ahurei. He tino pakari te uku alumina, tae atu ki te 9 te pakeke Mohs, tuarua ki te taimana, ā, ka taea te ātete ki te horo kaha o ngā matūriki rauemi. I taua wā, he tino pai hoki te ātete kakahu. Ko tōna ātete kakahu he 266 ngā wā i te maitai manganese me te 171.5 ngā wā i te rino maka konupora-tiketike, ka taea te whakaroa ake i te roa o te mahi a ngā taputapu. Hei tāpiri, he tino pai hoki te ātete pāmahana teitei o ngā taera uku alumina, ā, ka taea te mahi pumau i roto i te taiao pāmahana teitei o te 1200℃, e pai ai tā rātou mahi i roto i ngā tono ātete-kakahu mō ngā taputapu pāmahana teitei i roto i ngā tipu hiko.
I roto i te whakamahinga mahi o ngā tipu hiko, he ngāwari, he kanorau hoki ngā tikanga tāutanga o ngā pepa uku alumina. Ko ngā mea noa ko te momo piri, te momo tāuru me te momo whakarewa. Ko te tāutanga piri ko te piri pūmau i ngā pepa uku ki te mata o te taputapu mā roto i ngā piripiri motuhake e ātete ana ki te pāmahana teitei me te kaha teitei. He ngāwari te whakahaere i tēnei tikanga, ā, he pai mō ngā wāhanga he uaua te āhua. Ko te tāutanga tāuru ko te tukatuka i ngā awaawa ki te mata o te taputapu e rite ana ki te āhua o te pepa uku, me te whakauru i te pepa uku ki roto. He pai te pānga o tēnei tikanga ki te whakapiri, ā, he pai mō ngā wāhanga e pāngia ana e ngā kaha pānga nui ake. Ko te tāutanga whakarewa ko te whakapiri i ngā pepa uku ki te mata o te taputapu mā roto i tētahi tukanga whakarewa motuhake. He kaha te hononga, ā, he pai mō ngā wāhi he nui te pakaru me ngā āhuatanga mahi uaua.
Hei tauira, me tango te paipa taka waro o te pūnaha kawe waro o te tipu hiko. I mua i te tāutanga o ngā pereti uku alumina, nā te mimiti tonu o ngā matūriki waro, kua tino pakaru te pakitara paipa o te paipa taka waro, ā, me whakakapi i ia ono marama. Kāore i te piki ake te utu tiaki anake, engari i pāngia hoki te hanga noa o te tipu hiko. Whai muri i te whakaurunga piri o ngā pereti uku alumina, kua tino piki ake te ātete pakaru o te paipa taka waro, kua roa ake te huringa whakakapinga ki te 3 ki te 5 tau, ka whakaitihia te wā kore mahi mō te tiaki me te whakapai ake i te pai o te hanga.
Nā te whakamahinga o ngā taera uku alumina i roto i ngā wāhanga pēnei i ngā economizer me ngā superheater o te pūnaha poihau kua tutuki hoki ngā pānga ārai-kakahu pai. Kua roa ēnei wāhanga e pāngia ana e ngā pāmahana teitei me ngā taumata puehu teitei, ā, ka hua ake ngā raruraru kakahu me te waikura. Mā te tāuta i ngā taera uku alumina ki roto i te āhua whakairo, whakarewa rānei, ka hangaia he paparanga tiaki pakari, ka ātete pai ki te waikura me te waikura o te puehu pāmahana teitei, ka whakaiti i te tere kino o ngā wāhanga, ā, ka whakarei ake i te pumau me te haumaru o te mahi poihau.
Ko te whakamahinga o ngā pereki uku alumina i roto i ngā tipu hiko, ehara i te mea ka whakarei ake i te mahi ārai-kakahu o ngā taputapu anake, engari ka puta mai hoki he painga ōhanga nui. Mā te whakaiti i te auau o te tiaki me te whakakapinga o ngā taputapu kua heke ngā utu tiaki me ngā ngaronga wā kore mahi. Mā te whakaroa i te roa o te ratonga o ngā taputapu, te whakarei ake i tōna pono me te whai huatanga o te mahi, me te whakarato i tētahi taurangi kaha mō te hanga pumau o ngā tipu hiko. Mā te haere tonu o te hangarau, ka whānui ake ngā tūmanakohanga whakamahinga o ngā pereki uku alumina i roto i ngā tipu hiko, ā, e tika ana kia whai wāhi nui rātou ki ngā mara maha atu, hei āwhina i ngā tipu hiko kia tutuki ai te mahi whai hua, pumau me te ōhanga.
