Kev siv honeycomb ceramic regenerator
Honeycomb ceramic regenerator muaj cov txiaj ntsig zoo xws li kub tsis kam, tiv thaiv corrosion, thermal shock stability, siab zog, loj kub cia, thiab thermal conductivity zoo, thiab lub zog txuag thiab kev pab cuam lub neej yog zoo heev.Honeycomb ceramic regenerator yog cov khoom tseem ceeb ntawm regenerative burner, uas yog dav siv nyob rau hauv ntau yam cua sov rauv, kub moj tej tawg furnaces, kho cua sov rauv, tawg furnaces, roasters, nyob rau hauv furnaces xws li melting furnaces, soaking furnaces, thiab roj thiab roj boilers.
Cov teeb meem uas twb muaj lawm hauv kev siv honeycomb ceramic accumulators
Kev puas tsuaj ntawm honeycomb ceramic regenerator nyob rau hauv lub regenerator feem ntau tshwm sim nyob rau sab kub kub.Cov laj thawj tseem ceeb rau kev puas tsuaj yog raws li hauv qab no:
⑴ Kub kub reburning kab hloov tau zoo heev
Yog hais tias cov reburning kab ntawm lub regenerator hloov ntau dhau lawm, thiab txawv txav kub tshwm sim nyob rau hauv lub regenerator, pem hauv ntej kab regenerator yuav tsim ib tug loj qhov sib txawv tom qab shrinking vim qhov kub thiab txias, uas yog ib qho yooj yim mus ua txhaum lub regenerator thiab tsim ib tug ntau dhau qhov sib txawv. .Clearance.Thaum cov roj flue ntws los ntawm lub thawv cua sov, nws yuav dhau los ntawm lub tshav kub cia lub cev, kom lub cev kub tom qab tiv tauj cov roj flue kub.Yog tias qhov kub thiab txias siab dhau lawm, lub thawv ntim khoom cua sov poob nws cov khoom cua sov.
(2) Tsawg softening kub nyob rau hauv load
Yog hais tias lub softening kub nyob rau hauv load tsawg dhau, nyob rau hauv lub siab kub ntawm ib txwm siv los yog thaum kub kub tshwm sim, lub pem hauv ntej kab kub cia lub cev yuav vau thiab deform, thiab yuav muaj ib tug loj sib txawv nyob rau hauv lub Upper ib feem ntawm lub tshav kub cia. tank.
⑶ Corrosion kuj tsis tuaj yeem ua phem
Cov khoom tsim tshiab yuav tsum yog cov khoom siv nrog cov purity siab dua, uas muaj kev tiv thaiv zoo dua rau cov hlau oxide hmoov thiab plua plav hauv cov pa roj, txo cov adhesion, thiab txo qhov kev ua tau zoo ntawm cov regenerator los ntawm cov tshuaj tiv thaiv.puas lawm.
⑷ Tsis zoo thermal shock stability
Thaum lub sij hawm siv lub regenerator, lub high-temperature flue gas thiab cua txias yuav tsum alternated los ntawm.Rau qee qhov taw tes hauv lub tshuab hluav taws xob, nws qhov kub thiab txias yuav tsum tau nce sai thiab txo qis ntawm 100-200 ° C ib ntus.Qhov kev poob siab thermal no cuam tshuam rau lub tshav kub cia.Cov khoom siv lub cev puas tsuaj.Rau qee lub sijhawm, muaj qhov sib txawv ntawm qhov kub thiab txias hauv lub thawv cua sov.Rau ib lub cev kub cia, qhov kub ntawm qhov sib txawv ntawm txhua qhov yuav tsim thermal stress hauv cov khoom.Yog tias qhov thermal shock stability ntawm cov khoom tsis zoo, cov kab nrib pleb lossis txawm tias tawg yuav tshwm sim vim cov thermal shock thiab thermal stress nto sai tom qab muab tso rau hauv kev pabcuam.Feem ntau hais lus, cov kab nrib pleb tsis muaj qhov cuam tshuam loj rau kev siv, tab sis yog tias qhov kev puas tsuaj loj heev, cov dej ntws yuav raug thaiv los yog kab noj hniav yuav tsim nyob rau hauv lub tshuab regenerator tom qab tau tshuab tawm ntawm lub tshuab regenerator, kom lub regenerator tsis tuaj yeem ua haujlwm ib txwm. .
Honeycomb ceramic txheem
1. Tshawb xyuas cov dej nqus, qhov ntom ntom, thermal expansion coefficient, softening kub.
2. Tshawb xyuas lub zog zoo li qub, thermal poob siab tsis kam, zoo li zoo thiab qhov sib txawv ntawm honeycomb ceramics.
3. Kev sim txoj kev kuaj xyuas cov kua qaub thiab alkali corrosion tsis kam ntawm cov ntxeem tau ceramics
4. Cov txheej txheem kuaj xyuas kom pom tseeb porosity thiab muaj peev xwm ntawm cov porous ceramics
5. Kev txheeb xyuas qhov ntxeem tau ntawm ceramic permeability
