Izitini ze-SK32 kanye ne-SK34: Zilungele izimboni ezishisa kakhulu

Ezweni lezicelo zezimboni ezishisa kakhulu, izitini ze-SK32 kanye ne-SK34 zivelele njengezixazululo ezithembekile nezisebenza kahle kakhulu zokungaguquki. Lezi zitini ziyingxenye yochungechunge lwezitini ze-SK zobumba, ezidumile ngokumelana kwazo nokushisa okumangalisayo nokuqina kwazo.​

1. Ukwakheka Nokukhiqiza​

Izitini ze-SK32 kanye ne-SK34 ezenziwe ngobumba oluqinile zenziwe ngezinto zokusetshenziswa ezinhle kakhulu, okuhlanganisa ubumba oluqinile, i-chamotte ene-calcined, kanye ne-mullite. Inqubo yokukhiqiza ihilela amasu athuthukile aqinisekisa ukuthi izitini zinezimbobo ezincane, amandla aphezulu, kanye nokumelana okuhle kakhulu nokushisa, ukuguguleka, kanye nokugqwala.​

Isitini se-SK32

Izitini ze-SK32 ngokuvamile ziqukethe i-alumina engu-35 - 38%. Lokhu kuhlanganiswa kuzinika amandla okubamba okungu-≥1690 °C kanye nokubamba ngaphansi komthwalo (0.2 MPa) okungu-≥1320 °C. Zine-porosity ebonakalayo engu-20 - 24% kanye nobuningi obungu-2.05 - 2.1 g/cm³.​

Isitini se-SK34

Ngakolunye uhlangothi, izitini ze-SK34 zinokuqukethwe okuphezulu kwe-alumina, okusukela ku-38 - 42%. Lokhu kuphumela ekukhanyeni okuphezulu okungu-≥1710 °C kanye nokukhanyeni okungaphansi komthwalo (0.2 MPa) okungu-≥1340 °C. Ukuvuleka kwazo okubonakalayo kungu-19 - 23%, kanti ubuningi bungu-2.1 - 2.15 g/cm³.​

2. Izicelo​

Ngenxa yezakhiwo zazo ezinhle kakhulu, izitini ze-SK32 kanye ne-SK34 zisetshenziswa kakhulu ezimbonini ezahlukahlukene ezishisa kakhulu.

Izitshalo Zensimbi​

Ekwenzeni insimbi, izitini ze-SK34 yizona ezikhethwa kakhulu ezindongeni zesithando, ama-ladle, kanye neminye imishini yokushisa okuphezulu. Izimo zokushisa okukhulu ezitshalweni zensimbi zidinga izinto ezinokumelana nokushisa okuphezulu, kanti izitini ze-SK34 zilingana kahle nomlomo. Zingamelana nokushisa okukhulu futhi zivikele izakhiwo ezingaphansi ekulimaleni.​

Izitini ze-SK32, ezinokumelana nokushisa okuphansi kancane kodwa ezisasebenza kahle kakhulu, zivame ukusetshenziswa ezindaweni zesitshalo sensimbi ezivezwa ekushiseni okumaphakathi, njengezindwangu ezithile zesithando lapho izidingo zokushisa zingephezulu kakhulu.​

Imboni Yezinto Zobumba​

Zombili izitini ze-SK32 kanye ne-SK34 zivame ukusetshenziswa kuma-oven e-ceramic. Izitini ze-SK32 zifanele ama-oven asebenza emazingeni okushisa aphezulu, ahlinzeka ngokushisa okuthembekile kanye nokumelana nokushisa. Izitini ze-SK34, ezinamakhono azo aphezulu okumelana nokushisa, zisetshenziswa kuma-oven lapho kuhileleke khona amazinga okushisa aphezulu kakhulu, okuqinisekisa ikhwalithi yemikhiqizo ye-ceramic ngesikhathi sokushisa.​

Izitshalo Zesimende​

Kuma-oven ajikelezayo esimende, izitini ze-SK32 kanye ne-SK34 zidlala indima ebalulekile. Ukuchayeka isikhathi eside emazingeni okushisa aphezulu kanye nezinto ezihudulayo ezitshalweni zesimende kudinga izitini eziphikisayo ezinamandla amahle kakhulu okusebenza kanye nokumelana nokuguguleka. Izitini ze-SK32 zisetshenziswa ezingxenyeni zesithando lapho ukushisa kungekho emazingeni aphezulu kakhulu, kuyilapho izitini ze-SK34 zifakwa ezindaweni ezibhekene nokushisa okukhulu, njengendawo evuthayo yesithando.​

Izitshalo ze-Petrochemical kanye ne-Chemical​

Izitini ze-SK34 zisetshenziswa kabanzi kuma-reactor kanye nemishini yokushisa ezitshalweni ze-petrochemical kanye nezamakhemikhali. Lezi zitshalo zivame ukubhekana nokusabela kwamakhemikhali okushisa okuphezulu, futhi ikhono lezitini ze-SK34 lokumelana nokushisa kanye nokugqwala kwamakhemikhali lenza kube ukukhetha okuhle kakhulu. Izitini ze-SK32 zingasetshenziswa nakwezinye izinhlelo zokusebenza ngaphakathi kwalezi zitshalo lapho izimo zokushisa ziphakathi kakhulu.​

3. Izinzuzo​

Izitini ze-SK32 kanye ne-SK34 zinikeza izinzuzo eziningana ezenza zifiseleke kakhulu ekusetshenzisweni kwezinga lokushisa eliphezulu.

Ukumelana Nokushisa Okuhle Kakhulu​

Njengoba kushiwo ngaphambili, zombili izinhlobo zezitini zingamelana namazinga okushisa aphezulu. Ukuqina okuphezulu kanye nokusebenza kahle ngaphansi komthwalo kuqinisekisa ukuthi zingakwazi ukugcina ubuqotho besakhiwo sazo ngisho nasezindaweni ezishisa kakhulu nezinokushisa okukhulu.​

Ukushisa Okuphansi​

Zine-conduction ephansi yokushisa, okusho ukuthi zinciphisa ukulahleka kokushisa. Lesi sici asigcini nje ngokusiza ekugcineni izinga lokushisa elifunekayo ngaphakathi kwemishini yezimboni kodwa futhi sisiza ekunciphiseni ukusetshenziswa kwamandla. Ngokuvimbela ukushisa ekuphumeni, izitshalo zingasebenza kahle kakhulu futhi zibize kahle.​

Amandla Aphezulu Okusebenza Kwemishini​

Izitini ze-SK32 kanye ne-SK34 zinamandla amakhulu okusebenza. Lokhu kuzivumela ukuthi zibekezelele ukucindezeleka kokusebenza, ukuguguleka, kanye nomthelela owenzeka ezindaweni zezimboni. Ukuqina kwesakhiwo sazo kuqinisekisa impilo yenkonzo ende, kunciphisa isidingo sokushintsha njalo futhi ngaleyo ndlela konge izindleko zokulungisa.​

Ukumelana Okuhle Nokushisa Okukhulu Nokugqwala​

Izitini zimelana kakhulu nokuqhekeka kokushisa, okuwukuqhekeka noma ukuxebuka kwezinto ngenxa yokushintsha kwezinga lokushisa okusheshayo. Ziphinde zinikeze ukumelana okuhle kakhulu nokugqwala, ikakhulukazi ezindaweni ezicebile ngamakhemikhali. Lokhu kuzenza zifaneleke ukusetshenziswa ezimbonini eziningi lapho izinselele ezinjalo zivame khona.​

4. Ukukhetha Isitini Esifanele​

Uma unquma phakathi kwezitini ze-SK32 ne-SK34 zesicelo esithile, kunezinto eziningana okudingeka zicatshangelwe.
Izidingo Zokushisa​

Isici esibaluleke kakhulu izinga lokushisa elizovezwa kulo isitini. Uma ukusetshenziswa kuhilela amazinga okushisa aphezulu kakhulu, njengasezithandweni zokwenza insimbi noma ezitsheni ezithile zokushisa okuphezulu, izitini ze-SK34 ziyisinqumo esisobala. Kodwa-ke, ezisetshenzisweni ezinamazinga okushisa aphezulu ngokulingene, izitini ze-SK32 zinganikeza ikhambi elingabizi kakhulu ngaphandle kokudela ukusebenza okuningi.​

Indawo Yamakhemikhali​

Ukwakheka kwamakhemikhali endaweni lapho kuzosetshenziswa khona izitini nakho kubalulekile. Ezindaweni ezinamazinga aphezulu amakhemikhali agqwalisayo, ukumelana okungcono kokugqwala kwezitini ze-SK34 kungadingeka. Kodwa uma ukuvezwa kwamakhemikhali kuncane, izitini ze-SK32 zingase zanele.​
Izindleko Zokucatshangelwa​

Izitini ze-SK32 ngokuvamile zibiza kakhulu kunezitini ze-SK34. Uma izidingo zokushisa kanye namakhemikhali zesicelo zivuma, ukusebenzisa izitini ze-SK32 kungasiza ekunciphiseni izindleko zephrojekthi iyonke. Kodwa-ke, kubalulekile ukungayekethisi ekusebenzeni ngenxa yokonga izindleko.​

Ekuphetheni, izitini ze-SK32 kanye ne-SK34 ziyizinto ezimbili ezithembeke kakhulu ezingasetshenziswa ezimbonini ezishisa kakhulu. Izakhiwo zazo ezihlukile, ububanzi bezicelo, kanye nokusebenza kahle kwezindleko kwenza zibe ukukhetha okuhle kwezimboni ezahlukahlukene. Kungakhathaliseki ukuthi isitshalo sensimbi, imboni yezinto zobumba, isitshalo sikasimende, noma isikhungo se-petrochemical, lezi zitini zinganikeza ukumelana nokushisa okudingekayo kanye nokuqina ukuqinisekisa ukusebenza okubushelelezi nokusebenza kahle.​
