Seb siv dai cib los yogrefractory castablesrau hauv ob sab phlu ntawm cov khib nyiab kub incinerator suav nrog ntau yam ntawm kev xav, nrog rau cov khoom siv, kev siv, cov txiaj ntsig kev lag luam, thiab lwm yam. Cov hauv qab no yog cov ncauj lus kom ntxaws sib piv ntawm ob cov ntaub ntawv:
1. Kev sib piv ntawm cov khoom siv ua haujlwm
Dai cib
Cov txiaj ntsig zoo: cov khoom siv ntawm kev dai cov plaub fab feem ntau muaj cov zog ntau dua thiab cov tshuab tshuaj tua hluav taws xob, thiab tsis yooj yim rau tawg lossis tev tawm. Tsis tas li ntawd, cov thermal conductivity ntawm dai cib kuj zoo, uas yog qhov zoo rau kev nqus ntawm flue roj cua sov.
Disadvantages: Lub installation ntawm dai cib yog qhov nyuaj, yuav tsum tau vuam hooks thiab lwm yam accessories, thiab muaj cov kev xav tau siab rau kev tsim kho zoo. Nyob rau tib lub sijhawm, tus nqi ntawm dai cib feem ntau yog siab dua li ntawm castables.
Casting refractory castables cov ntaub ntawv
Qhov zoo: Castables muaj kev tsim kho zoo thiab tuaj yeem hloov kho rau kev tsim kho ntawm ob sab ntawm ntau yam duab. Nyob rau tib lub sijhawm, tus nqi ntawm cov castables kuj qis, thiab cov qauv tuaj yeem hloov kho raws li qhov xav tau kom ua tau raws li kev siv sib txawv.
Disadvantages: Qhov ntom thiab cov khoom siv ntawm cov castables feem ntau qis dua li cov cib dai, thiab lawv yooj yim corroded los ntawm corrosive tshuaj nyob rau hauv flue gas. Ntawm qhov kub thiab txias, castables yuav ua tsis tiav nyob rau hauv daim ntawv ntawm degradation thiab cracking, cuam tshuam rau lub sij hawm ntev ruaj khov ntawm lub cub tawg.
2. Kev sib piv ntawm kev siv
Tus nqi calorific ntawm khib nyiab: Tus nqi calorific ntawm cov khib nyiab nkag mus rau hauv qhov cub hluav taws kub ntawm cov khib nyiab incineration muaj qhov tseem ceeb ntawm kev xaiv cov khoom siv refractory. Thaum tus nqi calorific ntawm cov khib nyiab tsawg, cov roj flue kub kuj tseem qis, thiab cov castable tuaj yeem ua tau raws li qhov yuav tsum tau siv rau lub sijhawm no. Txawm li cas los xij, raws li tus nqi calorific ntawm cov khib nyiab nce, qhov kub ntawm cov pa roj kuj nce, thiab qhov kub thiab txias tsis kam thiab oxidation tsis kam ntawm cov dai cib yuav zoo dua.
Flue gas muaj pes tsawg leeg: Cov roj flue tsim thaum lub sij hawm incineration ntawm cov khib nyiab muaj ib tug complex muaj pes tsawg leeg thiab muaj ntau yam corrosive tshuaj. Cov cib dai zoo tuaj yeem tiv taus qhov yaig ntawm cov khoom corrosive vim lawv qhov ntom ntom thiab muaj peev xwm antioxidant. Castables yuav ua tsis tau vim yog yaig.
Rauv qauv: Cov qauv sib txawv ntawm lub cub tawg kuj tseem cuam tshuam rau kev xaiv cov khoom siv refractory. Piv txwv li, nyob rau hauv qee qhov tshwj xeeb rau cov khoom siv rauv, dai cib yuav yooj yim rau nruab thiab tswj; thaum nyob hauv lwm cov qauv, castables yuav hloov tau ntau dua.
3. Kev sib piv ntawm cov txiaj ntsig kev lag luam
Kev nqis peev pib: Kev nqis peev thawj zaug ntawm dai cib feem ntau yog siab dua li ntawm refractory castables, vim tias dai cib yuav tsum tau vuam hooks thiab lwm yam khoom siv, thiab yuav tsum muaj kev tsim kho ntau dua thiab cov kev xav tau zoo.
Kev khiav hauj lwm thiab kev saib xyuas: Nyob rau hauv cov nqe lus ntawm kev khiav hauj lwm thiab kev txij nkawm, dai cib muaj cov nqi kho mob qis vim lawv cov kav ntev thiab muaj peev xwm antioxidant. Castables yuav xav tau kev tu thiab hloov ntau zaus.
Cov txiaj ntsig mus sij hawm ntev: Los ntawm qhov kev xav ntawm cov txiaj ntsig ntev, txawm hais tias thawj zaug peev ntawm dai cib yog siab, tag nrho cov txiaj ntsig kev lag luam yuav siab dua vim lawv cov kav ntev thiab cov nqi tu qis. Txawm hais tias castables muaj kev nqis peev qis qis, qhov kev tu ncua ntev thiab hloov cov nqi yuav siab.
Hauv cov ntsiab lus, seb puas yuav siv cov cib dai lossis cov khoom siv hluav taws xob rau cov txheej txheem ntawm cov khib nyiab hluav taws xob hluav taws xob yuav tsum tau txiav txim siab zoo raws li kev siv tshwj xeeb thiab cov txiaj ntsig kev lag luam. Nyob rau hauv cov ntaub ntawv ntawm high calorific nqi ntawm cov khib nyiab, complex flue gas muaj pes tsawg leeg los yog siab yuav tsum tau rau cov ntaub ntawv refractory nyob rau hauv lub cub tawg qauv, dai cib yuav muaj ntau yam zoo. Nyob rau hauv cov ntaub ntawv uas tsis muaj calorific nqi ntawm cov khib nyiab, kuj tsis tshua muaj flue roj kub los yog tsawg yuav tsum tau rau cov ntaub ntawv refractory, castables tej zaum yuav ib tug ntau economic xaiv. Nyob rau tib lub sijhawm, yam xws li kev tsim kho nyuaj, cov nqi khoom siv thiab kev ua haujlwm ntev thiab kev saib xyuas yuav tsum tau txiav txim siab los txiav txim siab zaum kawg.
