Amathangi Angaphandle Anophahla Anophahla Lwangaphakathi: Okujwayelekile Ekugcinweni Kwamafutha Anzima (HFO)
I-Domed External Floating Roof Tank (EFRT) iyisimo esihle kakhulu sokugcina uwoyela osindayo (HFO) ezindaweni ezahlukahlukene. Ngokuhlanganisa amandla okunciphisa ukukhishwa komoya we-floating roof nezinzuzo zesakhiwo nokuvikela ezimweni zezulu ze-aluminum geodesic dome, lezi zingqongqo zinikeza isixazululo esiqinile sokuphatha i-HFO. I-dome ivikela i-floating roof emvula, ikhephu, nasemoyeni, kanti i-floating roof igcina indawo encane yomusi, ngokuhlanganyela yandisa impilo yempahla futhi ithuthukise ukusebenza kahle kwamandla ezinhlelo zokushisa uwoyela.
1. Ukuqonda Umklamo Ohlangene
I-Heavy Fuel Oil (HFO) iyimikhiqizo enamathelayo, enobuningi obuphezulu edinga izimo ezithile zokugcina. Ngokungafani nama-distillates alula (njenge-gasoline) adinga ama-EFRT ikakhulukazi ukunciphisa i-VOC, ukugcinwa kwe-HFO kuzuza ekucushweni kwe-Domed EFRT ngenxa yezinzuzo zesakhiwo nokushisa.
Izingxenye:
● I-External Floating Roof (EFR): Isakhiwo sangaphakathi esintantayo esintanta phezu kwe-HFO, cishe siqeda isikhala lapho izinsipho zingakwazi ukuqoqana.
● I-Geodesic Aluminum Dome: Isakhiwo esingasindi, esingaguguleki, esizisekelayo esihlanganisa ithangi lonke. Sithatha indawo yezindlu ezijwayelekile zensimbi eqinile, ezithambekele ekugugulekeni kusuka kuma-vapors e-HFO nomswakama womoya.
2. Kungani Ukhetha Ama-Domed EFRT we-Heavy Fuel Oil?
Onjiniyela bakhetha ama-domed EFRT wokugcinwa kwe-HFO ngoba axazulula "izinkinga ezithile" ezihlobene nokuphathwa kwamafutha anzima:
Ukusebenza Kahle Kokushisa Nokufudumeza
I-HFO kumele igcinwe ezingeni eliphezulu lokushisa ukuze ihlale iyaphumula. Ithangi lesitayela se-steel elinophahla oluqinile libhekene ne "wind chill" phezu kwendawo ephelele yephroof, okwandisa umthwalo wamandla kumajele okushisa. I-aluminium geodesic dome idala indawo ye-air dead esebenza njengendawo yokufaka, yehlisa kakhulu ukulahleka kokushisa nezindleko zamandla zokusebenza.
Ukuqedwa kwezingozi ezihlobene nesimo sezulu
Ku-EFRTs ejwayelekile, uphahla oluhlanganayo (floating roof) luyavulelwa izinto. Amanzi emvula angakwazi ukuqoqana ophahleni, abangele ukuthi uhlelo lokudonsa luhluleke noma uphahla luqunqele. I-geodesic dome ihlinzeka ngokuvikelwa okuphelele kwesimo sezulu, iqinisekisa ukuthi uphahla oluhlanganayo lusebenza endaweni eyomile, elawulwayo.
Ukuguguleka okuncishisiwe
I-HFO ivame ukuba ne-sulfur namanzi amancane. Ethangini elinophahla olungashintshi, imisoco ye-HFO ingakhandeka ngaphansi kophahla lwensimbi, okuholela ekugugulekeni okusheshayo nokunamandla. Ngokusebenzisa uphahla lwe-aluminium, ingqalasizinda iyakwazi ukumelana nemvelo egugulayo yesikhala sethangi.
3. Isiqhathaniso: Izixazululo Zokugcina i-HFO
Lapho ukhetha ithangi lokugcina uwoyela osindayo, abaphathi bezindawo kufanele balinganise izindleko zokuqala zemali (CAPEX) ngokonga isondlo eside nesokusebenza (OPEX).
Isici | Amathangi Ophahla Angaphandle Anophahla Lwangaphakathi (Domed EFRT) | Uphahla Olungashintshi (Insimbi) | I-Standard EFRT |
Ukuqothuka Kokushisa (Ukusebenza Kahle Kwokushisa) | Kubaluleke Kakhulu | Kulinganiselwe | Kubuthakathaka (Umoya Obandayo) |
Ukumelana Nokugqwala | Kubaluleke Kakhulu (Isivalo Sase-Aluminum) | Kubuthakathaka (Kudinga Ukugcotshwa) | Kulinganiselwe |
Ukuvikelwa Kwesimo Sezulu | Okuphelele | Okuyingxenye | Akukho (Uphahla Luyavuleka) |
Izidingo Zokugcinwa | Kuncane | Okuphezulu (Ukugqwala Kwangaphakathi) | Kulinganiselwe (Ukugeleza Kwamanzi) |
Inzuzo Eyinhloko | Ukusebenza kahle kwamandla & ukuphila isikhathi eside | Izindleko zokuqala eziphansi | Ukulawulwa kukavampire |
4. Izinto Ezibalulekile zobunjiniyela
Ukuze i-EFRT enesivalo isebenze kahle kakhulu kuwoyela onzima, kufanele kutholwe izindinganiso ezithile zobunjiniyela:
1. Izinhlelo Zokubopha: Kudingeka izinhlelo zokubopha eziyinhloko nezesibili ezisebenza kahle kakhulu ukuze kugcinwe isivalo phakathi kwesivalo esintantayo kanye nodonga lwesitanki, kuqinisekiswe ukubanjwa kukavampire ngisho naku-HFO enokujiya okuphezulu.
2. Umoya wokungenisa nokukhipha umoya: I-geodesic dome kumele ivunyelwe umoya kahle ukuze kugwenywe ukuqoqeka kwama-gesi avuthayo noma anobuthi endaweni engaphezulu, noma ngabe uphahla oludada lunciphisa ubukhona be-vapor.
3. Isisekelo nokuhlala: Uma kucatshangelwa isisindo se-HFO (esinzima kune-amanzi), isisekelo kumele sakhiwe ukuze sikwazi ukubhekana nemithwalo ephezulu ye-hydrostatic futhi simelane nokuhlala kwesikhathi eside.
4. Ukuhlanganiswa kokushisa: Umklamo kumele uvumele ukuhlanganiswa kwezishisi ze-suction noma izintambo zokushisa zangaphakathi, ezibalulekile ekugcineni uwoyela osindayo ezingeni lokushisa elifunekayo lokugeleza.
5. Imibuzo Evame Ukubuzwa (FAQ)
Q: Ingabe i-geodesic dome iyadingeka uma ngingenalo iqhwa noma imvula enkulu?
A: Ngisho nasezindaweni ezomile, i-dome ilusizo kuwoyela kaphethiloli osindayo. Inciphisa umthwalo wokushisa ethangini, ivimbela ukungcola (utshwala/isihlabathi) ukuthi kungangeni ethangini, futhi iqeda ukugcinwa okudingekayo ukuze kugcinwe uhlelo lokukhipha amanzi uphahla oludada luhlanzekile.
Q: Ingabe i-aluminium dome idinga ukupeyintwa?
A: Cha. Ama-aluminium geodesic domes aphezulu angaphumeleli ekugugeni futhi awadingi izindleko eziphezulu, eziphindaphindayo zokupenda ezidingwa amathangi engeziwe engeziwe, okwenza kube "faka futhi ukhohlwe" impahla.
Q: Lokhu kuhlelwa kuthinta kanjani ukuphepha komlilo?
A: I-dome inikeza inzuzo enkulu yokuphepha. Ivimbela ukuhlanganiswa kwe-vapors ezishisayo endaweni yokuphakela, futhi ivikela isikhwama sephroof esiphakamisayo ezimeni zangaphandle ezingase zibe nomthelela ekutheni i-vapor barrier ingaphazamiseka.
Ngokugcinwa kukaphethiloli osindayo (heavy fuel oil), i-Domed External Floating Roof Tank iyisinqumo sobunjiniyela esithuthukile esibeka phambili ukuqina nokusebenza kahle kwamandla. Ngokuhlukanisa uphahla oluhlanganayo (floating roof) emoyeni nokwenza kahle iphrofayili yokushisa yethangi, ukucushwa kwe-geodesic dome kunciphisa ukugcinwa, kuvikela impahla ekugugulekeni okuhlobene ne-HFO, futhi kunciphisa izindleko zokusebenza zesikhungo sokugcina impahla esikhathini eside.
Ngabe njengamanje ukhetha ukwakha indawo yokugcina amathangi ezimboni, noma ngabe ufuna ukulungisa ithangi elikhona elinephahla eliqinile (fixed-roof) le-HFO nge-geodesic dome?
