Amathangi Ensimbi Engagqwali Okugcina Uwoyela Wezimoto Ezisindayo: Ubunjiniyela Bokugcina Okunamandla Okuminyene
Ukugcinwa kwezimboni kuka-Heavy Fuel Oil (HFO)—kuhlanganise namafutha asele, amafutha e-bunker, kanye neziqeshana ezisindayo zikaphethiloli ezisetshenziswa ekukhiqizeni amandla, ekuhambiseni imikhumbi, nasezimbonini ezinkulu—kuveza izinselele zobunjiniyela eziyingqayizivele. Ngokungafani no-diesel olucwengekile olulula noma uphethiloli, i-HFO ibonakala ngokuminyana okuphezulu, ukungqubuzana okuphezulu kwe-kinematic emazingeni okushisa avamile, kanye nokugxila okuncane kwezinto ezikhipha isulfure ezikhipha ukugqwala nomswakama.
Amathangi endabuko ensimbi ekhabhoni avame ukuhlushwa ukugqwala kwangaphakathi okusheshayo uma evezwe emanzini ane-asidi agcwele phansi kanye nezinsalela eziqukethe isulfure. Amathangi okugcina uphethiloli osindayo ensimbi engagqwali ahlinzeka ngesixazululo esithuthukile, esingadingi ukunakekelwa, esihlanganisa ukuqina okuphezulu kokwakheka nokumelana okukhethekile nokugqwala kwamakhemikhali nokucekelwa phansi ukushisa.
1. Ukukhethwa Kwezinsimbi: I-Grade 316L vs. Insimbi Yekhabhoni
Ngenxa yokuthi uphethiloli osindayo uvame ukuqukatha amazinga ahlukahlukene esulfure, ama-naphthenic acid, kanye nomswakama womoya ojiyile, ukukhethwa kwezinto kubalulekile ekuqineni kwesakhiwo isikhathi eside:
● I-AISI 316L Stainless Steel: Icebise nge-molybdenum engu-2–3%, i-Grade 316L inikeza ukumelana okungcono kakhulu nokugqwala kwamachashaza nokugqwala kwemifantu uma kuqhathaniswa nensimbi ejwayelekile yekhabhoni noma i-Grade 304, okwenza ilungele indawo enobungozi obukhulu yodaka olungaphansi kwamathangi kaphethiloli.
● Ukuqedwa Kwezingqimba Zangaphakathi: Ngokungafani namathangi ensimbi ekhabhoni ancike ezingqimbheni zangaphakathi ze-organic epoxy noma ze-phenolic—ezingakwazi ukuqhuma, ukuxebuka, noma ukuncibilika lapho zivezwa ezingxenyeni zikaphethiloli ezishisayo—amathangi ensimbi engagqwali agcwele awadingi zingqimba zokuvikela zangaphakathi, ngaleyo ndlela aqeda izingozi zokungcola.
2. Ukuphathwa Kokushisa Nokulawula Ukujiya
Ngenxa yokuthi amafutha ezinto ezisindayo awagelezi kalula emazingeni okushisa asezingeni lokushisa, amathangi okugcina kumele ahlanganiswe nezinhlelo ezithuthukile zokulawula ukushisa:
● Amakhoyili Okushisisa Angaphakathi: Amabhange okushisisa ensimbi engagqwali noma amanzi ashisayo (noma ama-electric trace heaters) akhelwe eduze kwephansi lethangi ukuze agcine i-HFO emazingeni okushisa okumpompa (ngokuvamile 50°C kuya ku-90°C) ngaphandle kokushisa uphethiloli.
● Ukumboza Ukufakwa Kwe-insulation: Ukumboza kwe-mineral wool noma i-polyurethane insulation kufakwe ngaphandle kwe-aluminium skin ukuze kugcinwe amandla okushisa futhi kuncishiswe izindleko zokushisa.
I-Matrix Yokuqhathanisa: Izinto Zokugcina Amathangi Ka-HFO
Ipharamitha Yokuhlola | Amathangi e-Stainless Steel HFO | Amathangi e-Carbon Steel anama-Epoxy-Coated | Amathangi e-Carbon Steel angenama-Coating |
Ukumelana Nokugqwala | Ukumelana okuqhubekayo okujolile kwe-sulfur kanye namanzi asidi ezansi | Asengozini uma upende uqhubeka, uqhekeka, noma uguga | Ukugqwala okusheshayo nokuncipha kodonga ezindaweni ezinodaka |
Ukugcinwa Kwezingqimba | Akukho okudingekayo; ukwakhiwa kwensimbi eqinile | Idinga ukuhlanzwa ngaphakathi ngezikhathi ezithile, ukuhlanza nge-sand, nokuphinda kufakwe upende | Idinga ukuvikelwa okunamandla kwe-cathodic kanye nama-rust inhibitors |
Ukuhambisana Nokushisa | Ukumelana okuhle kakhulu namafutha okushisa aphezulu kanye nama-steam coils | Ingaphansi kwengcindezi yokwanda ngenxa yokushisa kanye nokuhlukaniswa kwepende | Amandla esakhiwo amahle, kodwa izindleko zokunakekela ziphezulu |
Isikhathi Sokulindeleka Sokuphila | Iminyaka engu-30 kuya kwengu-40+ yokusebenza okuqhubekayo okunzima | Iminyaka engu-15 kuya kwengu-25 (kuya ngokunakekelwa kolayini) | Iminyaka engu-10 kuya kwengu-20 (kuya kakhulu ngokuqondisa kokukhipha amanzi) |
Imibuzo Ejwayelekile (FAQ)
Umbuzo: Kungani kusetshenziswa insimbi engagqwali kumathangi okugcina uwoyela osindayo?
A: I-stainless steel inikeza ukumelana okukhulu nokugqwala kwe-sulfur, ama-acids e-naphthenic, kanye nokuhlanganiswa kokunetha okutholakala kuma-heavy fuel oils, kususa ingozi yokonakala kokuphakanyiswa kwangaphakathi kanye nezindleko zokulungisa amathangi.
Q: Yimuphi umkhiqizo we-alloy ophakanyisiwe kuma-HFO tanks?
A: I-AISI 316L iyaphakanyiswa kakhulu ngenxa yokuba nayo i-molybdenum, enikeza ukuvikelwa okwandisiwe ngokumelene nokugqwala kwe-pitting kanye nokuhlaselwa kwe-sludge e-asidi ezindaweni eziphansi zethangi.
Q: Kanjani i-heavy fuel oil igcinwa ibhula ngaphakathi kwethangi le-stainless steel?
A: Amathangi afakwe ama-coils e-steam e-stainless steel angaphakathi, ama-bundles amanzi ashisayo, noma izinto zokushisa zikagesi ezibekwe eduze phansi ukuze zehlise i-kinematic viscosity ye-oyela, kuvumela ukuhamba kahle kokuthatha nokuphumpa.
Q: Ingabe amathangi e-HFO ensimbi engagqwali adinga izingqimba zangaphakathi zokuvikela?
A: Cha. Ngenxa yokuthi insimbi engagqwali imelana nokugqwala kuyo yonke ingxenye yayo, izingqimba zangaphakathi ze-organic noma i-epoxy lining azidingeki nhlobo, ngaleyo ndlela kuvinjelwa ukuxebuka noma izinkinga zokungcola kaphethiloli.
