Waro Whakahohe – Ngā Āhua Whakaputa me te Hua

Ko ngā rauemi tīmatanga mō te hanga waro whakahohe ko: ngā rauemi mata kei roto he waro pērā i te rakau, te peat, te lignite, te waro mārō, ngā kakano hua pērā i te hinu oriwa, te anga kokonati , me ētahi atu. E rua ngā tikanga hei whakahohe i ēnei rauemi.

I roto i te whakahohenga hau, ka whakamahia ngā rauemi kua warohia kētia, ā, ka tukuna ki te awe waikura o te rerenga hau, pērā i te mamaoa wai, te hauhā waro, te hau, ngā ranunga rānei o aua mea. Ko te pāmahana whakahohenga he tata ki te 700–1000°C, ā, ka tahuna te waro i muri i te tauhohenga wai-hau, ka hangaia he anga waro pūwero, tino kaha.

I roto i te whakahohenga matū, ko te tikanga ka whakaranua tuatahitia ngā rauemi kāore i te warohia, kei roto he waro, ki ngā matū whakamaroke me ngā matū whakahāora. Kātahi ka whakamahanahia te ranunga hua ki te 400–800°C. Kātahi ka horoia ngā matū whakahohe—tae atu ki te konutea pūhaumāota, te waikawa phosphoric, te waikawa whanariki, me ētahi atu—ka whakahokia mai.

Ka mahia te whakahohenga i roto i ngā oumu hurihuri, i ngā oumu maha-wāhanga, i ngā oumu poutū, i ngā oumu moenga wai, i ngā tauhohenga moenga wai rānei.

Ko ngā momo hua noa mō te Waro Whakahohe ko:

he āhua porotaka te nuinga),

pakaru (ngā kirikiri, ngā waro whakahohe rānei i kuruhia),

paura i roto i ngā rahi matūriki kua tautuhia.

Ko ngā tikanga hanga motuhake ko:

waro whakahohe porowhita,

ngā muka waro whakahohe, ngā whāriki muka rānei,

ngā mea e kiia nei ko ngā "honikoma".

Ko ngā tikanga hanga me te whakahohe, tae atu ki te rauemi mata o raro, he pānga nui ki ngā āhuatanga o te waro whakahohe e pā ana ki tōna kaha mimiti i te wā e whakamahia ana. Ina koa, ko te rahi o te mata o roto me te hanganga o ngā pūwero e tino whakawhirinaki ana ki te tukanga whakahohe.
