Ukuvikelwa Kokuqhuma Kwezimboni Ezizenzekelayo: Ukubeka Eqhulwini Ukuphepha Ngaphezu Kwenzuzo
Ukuvikela ukuqhuma akuyona nje imfuneko yokuthobela—kuyisimiso sokuphepha esiyisisekelo. Njengoba abakhiqizi bemishini ezenzakalelayo baseShayina bekhula baba izimboni ezisengozini enkulu njengamakhemikhali e-petrochemicals, izimayini, namandla, ukuqonda amazinga okuvikela ukuqhuma kubaluleka kukho kokubili ukuncintisana komhlaba kanye nokuphepha kokusebenza.
Isayensi Engemuva Kokuqhuma Kwezimboni
Ukuqhuma kudinga izinto ezintathu ezibalulekile:
- Into EqhumayoAmagesi (i-hydrogen, i-methane), uketshezi (utshwala, uphethiloli), noma uthuli (ushukela, insimbi, ufulawa)
- I-oxidizer- I-oxygen ngokuvamile ikhona emoyeni
- Umthombo wokuthungela- Izinhlansi, izindawo ezishisayo, ukukhishwa okumile, noma ukusabela kwamakhemikhali
Isimiso esiyisisekelo sokuvimbela ukuqhuma sihilela ukususa noma iyiphi yalezi zici ezintathu.
Ukuqonda Izimpawu Zezinto Ezisetshenziswayo Zokuqhuma: "Ex ed IIC T6"
Lokhu kumaka okuvamile ezintweni ezingaqhumisi kukhombisa:
- Ex: Ukuhambisana nezindinganiso zokuvikela ukuqhuma
- e: Idizayini yokuphepha eyengeziwe
- d: Indawo ebiyelwe yi-flameproof
- I-IIC: Ifanele amagesi ayingozi kakhulu (i-hydrogen, i-acetylene)
- T6: Izinga lokushisa eliphezulu eliphezulu ≤85°C (iphephile ezintweni ezinamaphoyinti aphansi okuthungela)
Izindlela Zokuvikela Ukuqhuma Okuyisisekelo
Indawo engangenwa umlilo (Ex d)
Iklanyelwe ngokukhethekile ukuqukatha ukuqhuma kwangaphakathi futhi ivimbele ukuthungela komkhathi oyingozi wangaphandle.
Ukuphepha Kwangaphakathi (Ex i)
Ikhawulela amandla kagesi kumazinga angaphansi kwalokho okudingekayo ukuze ubangele ukuthungela, ngisho naphakathi kwezimo zamaphutha. Idinga izithiyo zokuzihlukanisa ukuze kugcinwe ukuphepha kulo lonke uhlelo.
Ukuhlukaniswa Kwendawo Eyingozi: Izindawo, Amaqembu Egesi Nezilinganiso Zezinga Lokushisa
Ukuhlukaniswa Kwendawo (Amazinga e-IEC)
- Indawo 0: Ukuba khona okuqhubekayo komkhathi oqhumayo
- Indawo 1: Cishe ubukhona phakathi nokusebenza okuvamile
- Indawo yesi-2: Ubukhona obungavamile noma obufushane bomkhathi oqhumayo
I-Gas Group Classification
- IIA: Amagesi anobungozi obuphansi (propane)
- IIB: Amagesi ayingozi emaphakathi (i-ethylene)
- I-IIC: Amagesi ayingozi kakhulu (i-acetylene, i-hydrogen)
Izinga lokushisa Izilinganiso
| I-T-Class | Ubukhulu Bezinga Lokushisa Lomhlaba |
|---|---|
| T1 | ≤450°C |
| T6 | ≤85°C |
Izingozi Zomlando: Izifundo Zokuphepha
- I-BP Texas City (2005): Izingozi eziyi-15 ezibangelwa ukushiswa komhwamuko we-hydrocarbon
- E-Buncefield, UK (2005): Ukuqhuma okukhulu komoya kaphethiloli okubangelwa ukugcwala ngokweqile kwethangi
- I-Imperial Sugar, USA (2008): Ukuqhuma kothuli kushone imiphefumulo engu-14 ngenxa yokungaphathwa ngendlela efanele endlini
Lezi zinhlekelele zigcizelela ukubaluleka okubalulekile kwezinhlelo zokuvikela ukuqhuma eziqinisekisiwe, ezifanele indawo.
Ukukhetha Izinsiza Ezizenzakalelayo Eziphephile: Okucatshangelwayo Okubalulekile
Lapho ukhetha izixazululo ezizenzakalelayo zezindawo eziyingozi, qinisekisa njalo:
- Ingabe okokusebenza kuyafana nezidingo zakho zendawo kanye neqembu legesi?
- Ingabe izinga lokushisa lifanele isicelo sakho?
- Ingabe zonke izingxenye ziyingxenye yesistimu eqinisekisiwe yokuvikela ukuqhuma?
Ungalokothi uhlehlekumazinga okuvikela ukuqhuma. Ukuphepha kufanele kube yikhona okugqugquzela izinqumo zokuklama—ngoba okusengcupheni kudlulela ngalé kokutshala izimali ezimpilweni zabantu.
