Ko e ha ʻa e kulupu mafana ʻo e meʻangaue fakaʻuhila

ʻOku hoko ʻa e fakafaʻahinga ʻo e ʻea ko ha fakaʻilonga maluʻi mahuʻinga ki hono fakafuofuaʻi ʻo e ignition ʻe malava ke maʻu ai ha ngaahi kasa ʻoku velangofua mo e meʻangaue fakaʻuhila. ʻOku fakafaʻahinga ʻa e ngaahi kasa velangofua ki ha kalasi ʻe ono ʻo makatuʻunga ʻi he mafana ʻo e afi, Neongo ʻoku fakafaʻahinga ʻa e meʻangaue fakaʻuhila ki ha faʻahinga ʻe ono ʻo makatuʻunga ʻi he mafana ʻo e ʻea, denoted ko T1, T2, T3, T4, T5, mo e T6. Neongo ia, ʻOku kehe ʻaupito ʻa e tuʻunga ʻo e fakakulupu ki he meʻangaue fakaʻuhila mo e ngaahi kasa ʻoku velangofua.

Ko e tefitoʻi moʻoni ʻoku ʻi mui ʻi he meʻangaue fakaʻuhila mafana ʻo e ʻea fakafaʻahinga, ʻoku ʻikai totonu ke hanga ʻe he mafana maʻolunga taha ʻoku ʻomi ʻe he meʻangaue ʻo fakaulo ʻa e ngaahi kasa ʻoku velangofua. ʻI hono fakalea ʻe niʻihi, kuo pau ke ʻoua naʻa laka hake ʻa e mafana ʻo e meʻangaue ʻi he mafana ignition ʻo e velangofua ngaahi kasa.

ʻOku mahuʻinga ke fakatokangaʻi ʻoku ʻa e mafana lahi taha ʻo e meʻangaue fakaʻuhila ki he fakaʻauha ʻoku ʻuhinga ia ki he mafana maʻolunga taha ʻe lava ke aʻu ki ai pe ngaahi konga ʻi he ngaahi tuʻunga angamaheni ʻo e ngaue pea ʻi he ngaahi tuʻunga faingataʻa taha kuo fakangofua. ʻOku totonu ke lava ʻe he mafana ko ʻeni ʻo igniting ʻa e ngaahi feituʻu takatakai fakafepakiʻi fefiofi e ʻea kasa.

Koeʻuhi ko e ngaahi faʻufaʻu kehekehe ʻo e fakamoʻoni, ʻe lava ke ʻuhinga ʻa e mafana ʻo e ʻea ki he ngaahi konga kehekehe ʻo e meʻangaue. Mahalo ko e mafana ia ʻi he tafaʻaki ki tuʻa ʻo e, ʻo hange ko flameproof meʻangaue fakaʻuhila, pe ko e mafana ʻo e ʻea ʻi he tafaʻaki ki tuʻa ʻo e meʻangaue ʻoku hivaʻi pe ngaahi konga pau ʻi loto, hangē ko e ʻi he tupulaki e malú pe pressurized meʻangaue fakaʻuhila.
