Combustible e faʻahinga fakaʻauha ʻo e kasa

ʻI hono fakafepakiʻi atmospheres, ʻOku mahuʻinga ʻa e ngaahi founga afi ʻo e ngaahi kasa combustible ke mahino. ʻOku kau heni ʻa e afi malohi maʻu pe, afi maʻu pe, deflagration, mo e detonation.

1. Ko e afi ʻoku ne teke maʻu pe:

ʻOku hoko ʻa e founga ko ʻeni ʻi he ngaahi feituʻu ʻoku ava ai ʻa e ngaahi meʻa ʻe lava ke mole ai ʻa e afi, tauhi ʻo e potupotutatau mo e malohi ʻo e takai. Ko ha founga lelei ia, tauʻataina mei he ngaahi peau malohi, fakafotunga ʻe ha vave pau ʻo e ʻa e afi ʻOku makatuʻunga ia ʻi hono ʻomi ʻo e penisini mo e tali.

2. Fakaʻauha maʻu pe:

Hoko ʻi loto ʻi ha faʻoʻanga meʻa tuʻumaʻu, ʻOku faʻa kamata fakalotofonua ʻa e afi lelei ko ʻeni pea mafola. ʻI ha faʻahinga tukunga pehe, kehekehe ʻa e fakangatangata ʻo e fakaʻauha, fie maʻu ha founga ʻoku hokohoko. ʻI he angamahení, ʻe lava ke hoko ʻa e malohi ʻo e fakaʻauha 7-9 taimi ʻe niʻihi ʻa e ʻuluaki malohi ki hydrocarbon kasa mixtures.

3. Deflagration:

ʻOku kau ai ʻa e mamalie ulo ʻo e afi vave koeʻuhi ko e taʻotaʻofi pe moveuveu, fakaiku ki ha peau malohi. Kehe mei he afi ʻoku malohi maʻu pe, ʻa e peau malohi mo e ulo ʻi muʻa subsonically. ʻOku ko ha meʻa angamaheni ʻi he lolotonga, faʻa fakaʻaliʻali ha peau faingataʻa mo ha faʻunga fakasouni.

4. Detonation:

Ko e founga lahi taha ʻo e fakaʻauha kasa, fakaʻilongaʻi ʻe ha peau oma ange malohi. Ki hydrocarbon kasa-ʻea mixtures, ʻe lava ke maʻolunga ʻaupito ʻa e detonation talangofuaʻa mo e teke.

ʻOku mahuʻinga ʻa e mahino ʻo e ngaahi founga ko ʻeni ki hono fakaʻehiʻehi mei he lolotonga. Deflagration, kae tautautefito ki he, lava ʻo fakavaivaiʻi pe fakalahi ki ha detonation ʻi ha ngaahi tukunga pau, ko ia mitigating ʻoku mahuʻinga ʻa e ngaahi moʻoniʻi meʻa te ne lava ʻo fakavaveʻi ʻa e ulo propagation.
