Ukwakhiwa nokwakhiwa kwezintambo zokushisa zohlobo lwebell
Uhlolojikelele:
Ohlobo lwensimbi yensimbi esetshenziselwa ikakhulukazi ukufakwa kokuncishiswa okukhanyayo nokwelashwa kokushisa, ngakho-ke ayiziko lokushisa elihlukahlukanayo. Izinga lokushisa lihlala phakathi kuka-650 no-1100 ℃ ikakhulu, futhi liguquka ngesikhathi esichazwe kusistimu yokushisa. Ngokususelwa ekulayisheni iziko lwensimbi yensimbi, kunezinhlobo ezimbili: isithando somlilo esiyinsimbi eyisikwele kanye nesithando somlilo esiyinsimbi esiyindilinga. Imithombo yokushisa yamakholishi ohlobo lwensimbi ikakhulukazi igesi, ilandelwa ugesi namafutha amancane. Ngokuvamile, amaziko ohlobo lwensimbi aqukethe izingxenye ezintathu: ikhava engaphandle, ikhava yangaphakathi, nesitofu. Idivayisi yomlilo ivame ukusethwa kukhava wangaphandle efakwe ungqimba oshisayo, kanti okokusebenza kubekwa kwikhava yangaphakathi yokushisa nokupholisa.
Ohlobo lwe-Bell-uhlobo lunokuqina komoya okuhle, ukulahleka kokushisa okuphansi, nokusebenza kahle okuphezulu kokushisa. Ngaphezu kwalokho, azidingi mnyango wesithando somlilo noma umshini wokuphakamisa nezinye izindlela ezahlukahlukene zokuhambisa imishini, ngakho-ke zigcina izindleko futhi zisetshenziswa kakhulu ezithandweni zokwelashwa kokushisa.
Izidingo ezimbili ezibucayi kakhulu zezinto zokufaka isithando somlilo isisindo esincane nokusebenza kahle kwamandla kwezembozo zokushisa.
Izinkinga ezijwayelekile nge-refracto yendabuko engasindiry izitini noma i-lightweight castable stukonakala kubandakanya:
1. Izinto zokwakha ezinamandla amakhulu adonsela phansi (ngokuvamile izitini ezingasindi ezikhanyayo zinamandla adonsela phansi ka-600KG / m3 noma ngaphezulu; okulula okungasakazwa kune-1000 KG / m3 noma ngaphezulu) kudinga umthwalo omkhulu kunhlaka yensimbi yesembozo sesithando, ngakho-ke ukusetshenziswa kwesakhiwo sensimbi kanye nokutshalwa kwemali ekwandeni kwesithando somlilo kuyanda.
2. Ikhava engaphandle enkulu ithinta umthamo wokuphakamisa kanye nendawo ephansi yezindawo zokusebenzela zokukhiqiza.
3. Isithando somlilo wensimbi siqhutshwa emazingeni okushisa ahlukahlukene ngezikhathi ezithile, futhi izitini ezikhanyayo ezikhanyayo noma ukukhanya okukhanyayo kunamandla amakhulu okushisa, ukuhambisa okuphezulu kokushisa, namandla amakhulu.
Kodwa-ke, imikhiqizo ye-fiber ye-CCEWOOL ekhanyelayo ine-conductivity ephansi yokushisa, isitoreji esiphansi sokushisa, kanye nobukhulu bevolumu ephansi, okuyizizathu eziyinhloko zokusebenzisa kwazo okubanzi kumakhava wokushisa. Izici zimi kanje:
1. Ibanga lokushisa elibanzi lokusebenza kanye namafomu okufaka izicelo ahlukahlukene
Ngokuthuthukiswa kokukhiqizwa kwe-ceramic fiber nobuchwepheshe be-CCEWOOL, imikhiqizo ye-CCEWOOL fiber ceramic izuze ukusebenza kwe-serialization nokusebenza. Ngokuya ngamazinga okushisa, imikhiqizo ingahlangabezana nezidingo zamazinga okushisa ahlukahlukene asukela ku-600 ℃ kuye ku-1500 ℃. Ngokuya nge-morphology, imikhiqizo iye yathuthukisa kancane kancane izinhlobo ezahlukahlukene zokucubungula noma imikhiqizo yokucubungula ejulile kusuka kukotini wendabuko, izingubo zokulala, imikhiqizo ezwayo kumamojula we-fiber, amabhodi, izingxenye ezimise okhethekile, iphepha, izindwangu ze-fiber njalonjalo. Bangakwazi ukuhlangabezana ngokugcwele nezidingo zamakhishi ezimboni zemikhiqizo ye-ceramic fiber ezimbonini ezahlukahlukene.
2.Umthamo omncane wevolumu:
Ubuningi bevolumu yemikhiqizo ye-ceramic fiber ngokuvamile ingama-96 ~ 160kg / m3, okucishe kube yi-1/3 yezitini ezingasindi kanye no-1/5 we-lightweight refractory castable. Okomlilo osanda kwaklanywa, ukusetshenziswa kwemikhiqizo ye-ceramic fiber akukwazi ukugcina insimbi kuphela, kepha futhi kwenza ukulayishwa / ukwehliswa kanye nokuthuthwa kalula, kuphakamisa inqubekela phambili kubuchwepheshe besithando somlilo.
3. Amandla amancane okushisa nokugcina ukushisa:
Uma kuqhathaniswa nezitini ezikhombayo nezitini zokwambathisa, umthamo wemikhiqizo ye-ceramic fiber uphansi kakhulu, cishe u-1 / 14-1 / 13 wezitini ezikhombayo no-1 / 7-1 / 6 wezitini zokwambathisa. Esithandweni sebheli esisebenza ngezikhathi ezithile, kungagcinwa inani elikhulu lokusetshenziswa kukaphethiloli okungahlobene nokukhiqiza.
4. Ukwakhiwa okulula, isikhathi esifushane
Njengoba izingubo zokulala ze-ceramic fiber namamojula anokunwebeka okuhle kakhulu, inani lokucindezelwa lingabikezelwa, futhi asikho isidingo sokushiya amalunga wokunweba ngesikhathi sokwakha. Ngenxa yalokhu, ukwakhiwa kulula futhi kulula, okungaphothulwa ngabasebenzi abanamakhono avamile.
5. Ukusebenza ngaphandle kwehhavini
Ngokwamukela ulwelwesi olugcwele-fiber, amaziko angasheshe afudumale ekushiseni kwenqubo uma kungavinjelwe ezinye izinto zensimbi, okuthuthukisa kakhulu ukusetshenziswa ngempumelelo kwamafektri ezimboni futhi kunciphise ukusetshenziswa kukaphethiloli okungahlobene nokukhiqiza.
6. Ukuqhuba okuphansi kakhulu kokushisa
Ifayibha ye-Ceramic iyinhlanganisela yemicu enobubanzi obungu-3-5um, ngakho-ke ine-conductivity ephansi kakhulu yokushisa. Isibonelo, lapho ingubo yokumboza ene-aluminium ephezulu ene-128kg / m3 efinyelela ku-1000 ℃ endaweni eshisayo, i-coefficient yayo yokudlulisa ukushisa ingu-0.22 kuphela (W / MK).
7.Ukuzinza okuhle kwamakhemikhali nokumelana nokuguguleka komoya:
I-fibre ye-Ceramic ingasuswa kuphela ku-phosphoric acid, i-hydrofluoric acid, ne-alkali eshisayo, futhi izinzile kweminye imithombo yezindaba ebhubhisayo. Ngaphezu kwalokho, amamojula e-ceramic fiber enziwa ngokugoqa ngokuqhubekayo izingubo ze-ceramic fiber ezingeni elithile lokucindezela. Ngemuva kokuphathwa kobuso, ukumelana nokuguguleka komoya kungafinyelela ku-30m / s.
Isakhiwo sesicelo se-fiber ceramic
Isakhiwo se-lining esivamile sekhava yokushisa
Indawo yokushisa yesembozo sokushisa: Yamukela isakhiwo esihlanganisiwe samamojula we-ceramic fiber kanye namakhaphethi we-ceramic fiber. Okokusebenza kwezingubo zokulala ezingemuva kungaba ibanga elilodwa liphansi kunokwaziswa kwento yensimbi yesendlalelo sendawo eshisayo. Amamojula ahlelwe ngohlobo "lwebutho lamasosha" futhi alungiswa nge-angle yensimbi noma amamojula amisiwe.
Imojula yensimbi yensimbi iyindlela elula yokufaka nokusetshenziswa njengoba inesakhiwo esilula sokubambelela futhi ingavikela ubucayi besithambo sesithando somlilo ngezinga elikhulu kakhulu.
Izindawo ezingaphezulu kwe-burner
Indlela yokubeka yezingubo ze-ceramic fiber blanket ze-CCEWOOL iyamukelwa. Ukufakwa kwesithando somlilo ngokuvamile kudinga izingqimba eziyi-6 kuya kwezi-9, ezilungiswa ngezikulufo zensimbi ezingamelana nokushisa, izikulufo, amakhadi asheshayo, amakhadi ajikelezayo, nezinye izingxenye zokulungisa. Izingubo zokulala ze-ceramic ezinesilinganiso esiphakeme zisetshenziswa cishe ngo-150 mm eduze kwendawo eshisayo, kanti ezinye izingxenye zisebenzisa izingubo zokulala ze-ceramic fiber esezingeni eliphansi. Lapho ubeka izingubo zokulala, amalunga kufanele okungenani ahlukane ngo-100 mm. Izingubo zokulala zangaphakathi ze-ceramic zihlanganiswe ngezinqe ukusiza ukwakhiwa, futhi izingqimba ebusweni obushisayo zithatha indlela edlulanayo yokuqinisekisa imiphumela yokuvalwa.
Imiphumela yokusetshenziswa kwe-ceramic fiber lining
Imiphumela yokwakhiwa kwe-fiber egcwele ikhava yokushisa yamakholomu yensimbi ihlale mihle kakhulu. Isembozo sangaphandle esisebenzisa lesi sakhiwo asiqinisekisi kuphela ukufakwa okuhle, kepha futhi senza ukwakhiwa okulula; ngakho-ke, kuyisakhiwo esisha esinamanani amakhulu wokuphromotha we-cylindrical heating furnace.
