Kapangidwe ndi Kusintha kwa ulusi woteteza kutentha wa Ironmaking Blast Furnaces ndi Hot-blast furnaces
Chiyambi cha kapangidwe koyambirira ka kutchinjiriza kwa ng'anjo zophulika ndi ng'anjo zotentha:
Chitofu chophulika ndi mtundu wa chipangizo chotenthetsera chomwe chili ndi kapangidwe kovuta. Ndicho chipangizo chachikulu chopangira chitsulo ndipo chili ndi ubwino wotulutsa zinthu zambiri, kupanga zinthu zambiri, komanso mtengo wotsika.
Popeza kutentha kwa gawo lililonse la ng'anjo yophulika ndi kwakukulu kwambiri, ndipo gawo lililonse limakhudzidwa ndi mphamvu zamakina, monga kukangana ndi kukhudzidwa ndi mphamvu yogwa, zinthu zambiri zotenthetsera pamwamba zimagwiritsa ntchito njerwa zowunikira kutentha kwambiri za CCEFIRE zomwe zimabwera ndi kutentha kwambiri pansi pa katundu komanso mphamvu zabwino zamakina kutentha kwambiri.
Monga chimodzi mwa zida zazikulu zothandizira ng'anjo yophulika, ng'anjo yotentha imapereka kutentha kwambiri ku ng'anjo yophulika pogwiritsa ntchito kutentha kuchokera ku kuyaka kwa gasi ya ng'anjo yophulika komanso zotsatira za kusinthana kwa kutentha kwa lattice ya njerwa. Popeza gawo lililonse limakhala ndi kutentha kwambiri kwa kuyaka kwa gasi, kukokoloka kwa fumbi komwe kumabwera chifukwa cha mpweya, komanso kusaka kwa mpweya woyaka, zinthu zotentha pamwamba nthawi zambiri zimasankha njerwa zoteteza kuwala za CCEFIRE, konkriti yosatentha, njerwa zadothi, ndi zipangizo zina zomwe zili ndi mphamvu zabwino zamakanika.
Pofuna kuonetsetsa kuti kutentha kwa mkati mwa ng'anjo kumakhudza bwino, kutsatira mfundo zosankha zipangizo zodalirika, zotsika mtengo komanso zomveka bwino, mkati mwa ng'anjo yotentha yogwira ntchito ndi ng'anjo yotentha nthawi zambiri mumasankha zipangizo zotetezera kutentha zomwe zimakhala ndi kutentha kochepa komanso magwiridwe antchito abwino otetezera kutentha.
Njira yachikhalidwe kwambiri ndiyo kusankha zinthu zopangidwa ndi bolodi la calcium silicate, zomwe zili ndi kapangidwe kake kameneka koteteza kutentha: njerwa zowunikira kwambiri za aluminiyamu + kapangidwe ka bolodi la silica-calcium zokhala ndi makulidwe oteteza kutentha pafupifupi 1000mm.
Kapangidwe kake ka kutchinjiriza kutentha kali ndi zolakwika zotsatirazi pakugwiritsa ntchito:
A. Zipangizo zotetezera kutentha zimakhala ndi mphamvu zambiri zoyendetsera kutentha komanso zimakhala ndi zotsatira zoyipa zoteteza kutentha.
B. Ma board a silicon-calcium omwe amagwiritsidwa ntchito kumbuyo kwa khoma amatha kusweka mosavuta, kupanga mabowo atasweka, ndikupangitsa kuti kutentha kutayike.
C. Kutayika kwakukulu kwa malo osungira kutentha, zomwe zimapangitsa kuti mphamvu ziwonongeke.
D. Mabodi a calcium silicate amayamwa madzi mwamphamvu, ndi osavuta kuswa, ndipo sagwira ntchito bwino pomanga.
E. Kutentha kwa ntchito ya calcium silicate boards ndi kochepa pa 600℃
Zipangizo zotetezera kutentha zomwe zimagwiritsidwa ntchito mu ng'anjo yophulika ndi ng'anjo yake yotentha ziyenera kukhala ndi mphamvu yabwino yotetezera kutentha. Ngakhale kuti mphamvu ya kutentha ya matabwa a calcium silicate ndi yotsika kuposa ya njerwa zosasunthika ndipo mphamvu ya kutentha yakhala ikukwera, chifukwa cha kutalika kwa thupi la ng'anjo ndi mainchesi akuluakulu a ng'anjo, matabwa a calcium silicate amasweka mosavuta panthawi yomanga chifukwa cha kufooka kwawo, zomwe zimapangitsa kuti insulation ya kumbuyo isakwanire komanso zotsatira zosakwanira za insulation. Chifukwa chake, kuti apititse patsogolo mphamvu ya kutentha ya ng'anjo yophulika ndi ng'anjo yotentha, zinthu zopangidwa ndi ulusi wa CCEWOOL ceramic (njerwa/mabolodi) zakhala zinthu zabwino kwambiri zotetezera kutentha pa iwo.
Kusanthula kwa magwiridwe antchito aukadaulo a ceramic fiberboards:
Ma CCEWOOL ceramic fiberboards amagwiritsa ntchito ulusi wapamwamba kwambiri wa AL2O3+SiO2=97-99% ngati zinthu zopangira, kuphatikiza ndi zomangira zopanda chilengedwe ngati thupi lalikulu ndi zodzaza ndi zowonjezera kutentha kwambiri. Zimapangidwa ndi kusakaniza ndi kupukuta ndi kufinya vacuum suction. Zinthuzo zikauma, zimakonzedwa kudzera mu zida zingapo zomangira kuti amalize njira zokonzera, monga kudula, kupukuta, ndi kuboola kuti zitsimikizire kuti magwiridwe antchito azinthu ndi kulondola kwa miyeso kuli pamlingo wapamwamba padziko lonse lapansi. Zinthu zawo zazikulu zaukadaulo ndi izi:
a. Kuyera kwambiri kwa mankhwala: komwe kuli 97-99% ma oxide otentha kwambiri monga Al2O3 ndi SiO2, zomwe zimatsimikizira kuti zinthuzo sizitentha kwambiri. Ma CCEWOOL ceramic fiberboards sangangosintha matabwa a calcium silicate ngati khoma la ng'anjo, komanso amagwiritsidwa ntchito mwachindunji pamwamba pa makoma a ng'anjo kuti azitha kupirira kukokoloka kwa nthaka ndi mphepo.
b. Kutsika kwa kutentha komanso zotsatira zabwino zoteteza kutentha: Chifukwa chakuti mankhwalawa ndi CCEWOOL ceramic fiber yopangidwa ndi njira yapadera yopangira mosalekeza, ali ndi magwiridwe antchito abwino kuposa njerwa zadothi zachikhalidwe za diatomaceous, calcium silicate boards ndi zinthu zina zophatikizika za silicate zomwe zimapangitsa kutentha kukhala kochepa, zotsatira zabwino zosungira kutentha, komanso zotsatira zabwino zopulumutsa mphamvu.
c. Mphamvu kwambiri komanso yosavuta kugwiritsa ntchito: Zogulitsazi zili ndi mphamvu zambiri zopondereza komanso zopindika ndipo sizimaphwanyika, kotero zimakwaniritsa zofunikira za zipangizo zolimba kumbuyo. Zingagwiritsidwe ntchito pa ntchito iliyonse yotetezera kutentha zomwe zimafunikira mphamvu zambiri, m'malo mwa zipangizo zophimba kumbuyo za mabulangeti kapena ma felt. Pakadali pano, ma CCEWOOL ceramic fiberboards okonzedwa ali ndi miyeso yolondola ya geometry ndipo amatha kudulidwa ndikukonzedwa momwe akufunira. Kapangidwe kake ndi kosavuta kwambiri, komwe kumathetsa mavuto a kusweka, kufooka komanso kuwonongeka kwakukulu kwa calcium silicate boards. Amafupikitsa kwambiri nthawi yomanga ndikuchepetsa ndalama zomanga.
Mwachidule, ma CCEWOOL ceramic fiberboards opangidwa ndi vacuum forming samangokhala ndi makhalidwe abwino kwambiri a makina komanso miyeso yeniyeni ya geometry, komanso amasunga mawonekedwe abwino kwambiri a zinthu zotetezera kutentha za ulusi. Amatha kusintha ma calcium silicate boards ndikugwiritsidwa ntchito m'minda yotetezera kutentha yomwe imafuna kulimba, kudzisamalira komanso kukana moto.
Kapangidwe ka ma ceramic fiberboards mu ng'anjo zophulika zopangira zitsulo ndi ng'anjo zotentha zophulika
Kapangidwe ka CCEWOOL ceramic fiberboards mu ng'anjo zopangira zitsulo kamagwiritsidwa ntchito makamaka ngati kumbuyo kwa njerwa zotsukira za silicon carbide, njerwa zadothi zapamwamba kapena njerwa zotsukira za alumina zapamwamba, m'malo mwa calcium silicate boards (kapena njerwa za diatomaceous earth).
Kugwiritsa ntchito pa ng'anjo zophulika zopangira chitsulo ndi ng'anjo zophulika zotentha
Ma CCEWOOL ceramic fiberboards amatha kusintha kapangidwe ka matabwa a calcium silicate (kapena njerwa za diatomaceous earth), ndipo chifukwa cha ubwino wawo, monga kutentha kochepa, kutentha kwambiri komwe kumagwiritsidwa ntchito, magwiridwe antchito abwino kwambiri opangira makina, komanso kusayamwa madzi, amathetsa mavuto omwe kapangidwe koyambirira kali nawo, mwachitsanzo, zotsatira zoyipa za kutentha, kutaya kutentha kwakukulu, kuwonongeka kwakukulu kwa matabwa a calcium silicate, magwiridwe antchito osalimba, komanso moyo wautali wautumiki wa insulation. Apeza zotsatira zabwino kwambiri pakugwiritsa ntchito.
