Whakaahuatanga
Ko nga ngongo boiler he paipa korekore.He rite tonu nga tikanga whakangao ki te ngongo kore, engari kei a ia nga whakaritenga kaha mo te hanga paipa maitai.E ai ki te taumata o te pāmahana, ka wehea te ngongo kohu ki nga ngongo kohua whanui me te ngongo kohua teitei.
Nga tikanga whakaputa:
① te pāmahana ngongo kōhua whānui kei raro i te 450 ℃, te whakamahi i te putorino wera-whakatakahia ranei te ngongo matao unu hanga paipa maitai.
② nui-pēhanga ngongo kōhua whakamahia maha i roto i ngā āhuatanga o te pāmahana teitei me te putorino pēhanga teitei, te pānga o te hau rewharewha tiketike pāmahana me te kohu wai, hāora me te waikura.putorino maitai ki te kaha pakaru nui, ātete tiketike ki te waikura hāora me te pai te pūmautanga whakahaere.
Ko nga kaupapa o nga ngongo boiler:
① Ko te nuinga o nga ngongo kohua ka whakamahia ki te hanga ngongo taiepa wai, ngongo i roto i te wai koropuputanga me te putorino mamaoa tino wera, nga ngongo korokoro korowha tino wera, te paipa auahi nui me te iti me te pereki paipa paipa.
② Ko te nuinga o nga wa e whakamahia ana ki te hanga i te pehanga teitei me te ultra-high pressure boiler super whakawera ngongo, ngongo whakamahana, te ararere, te putorino mamaoa matua.
Kāwai:
Ko nga ngongo kohua whanui me nga ngongo kohu kohu pehanga teitei ka kitea ki te mahi pāmahana teitei.Ko nga ngongo kohu i roto i te whanui, ko nga ngongo kohua teitei ranei e rite ana ki to raatau whakamahinga ka taea te wehewehe ki nga momo putorino maitai.
