Kev ua haujlwm ib puag ncig ntawm gasifier nws tus kheej yog qhov phem heev, thiab nws cov tshuaj tiv thaiv combustion yog qhov muaj zog txo qhov cua, thiab nws kuj raug kev txom nyem los ntawm kev yaig tsis tu ncua ntawm acidic slag thiab yaig ntawm high-speed kua. Vim tias qhov kev xav tau ntawm cov slag tawm, qhov kev khiav hauj lwm kub ntawm cov roj av slurry gasifier feem ntau yog 50 ~ 100 degree siab tshaj qhov melting point ntawm thee tshauv slag, kua slag ua rau hnyav yaig ntawm cov ntaub ntawv refractory. Tseem muaj ntau yam teeb meem uas yuav tsum tau txhim kho ntxiv hauv kev siv chrome-corundum cib hauv gasifier.
Cov ntaub ntawv refractory feem ntau yog Tuam Tshoj Refractory Brick, siab aluminium cib, castable, siab aluminium refractory cib, thermal rwb thaiv tsev cib, siab aluminium hnav-resistant cib, av nplaum thermal rwb thaiv tsev cib, lub teeb siab aluminium cib. Kev sib xyaw ua ke ntawm cov khoom siv refractory hauv cov txheej txheem ntawm kev siv muaj rau hauv qab no rau:
1. Kev pabcuam lub neej ntawm chrome corundum cib yuav tsum tau txhim kho ntxiv
Lub neej kev pab cuam ntawm chrome corundum cib nyob rau hauv gasifier chim lub cev thiab vault yog feem ntau 8000 ~ 20000h, thiab hais tias ntawm slag lub qhov ncauj thiab lub khob hliav qab high-chrome cib feem ntau yog 3000 ~ 6000h. Qhov tsis sib haum xeeb ntawm kev pabcuam lub neej ntawm txhua feem cuam tshuam rau tag nrho cov kev pabcuam lub neej ntawm gasifier thiab kev sib dhos ntawm tag nrho cov khoom, thiab ua rau cov nqi khiav lag luam. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tsum tau ua raws li cov kev tshawb fawb thiab ntxiv txhim kho lub neej kev pab cuam ntawm siab chromium cib.
2. Qhov teeb meem sintering yuav tsum tau kawm ntxiv thiab daws
Lub siab volatility ntawm Cr2O3 ua rau nws nyuaj rau sintered thiab densified. Txhawm rau ua kom cov ntaub ntawv Cr2O3 tag nrho sintered, tuaj yeem raug coj los tswj kev kub hnyiab ntawm qhov chaw tsis muaj zog, siv cladding sintering, ntxiv sintering pab, kev taw qhia txog nanomaterials, ntxiv sintering ua ke nrog cov ntaub ntawv thiab lwm yam txhais tau tias los txhim kho sintering kev ua tau zoo ntawm high chromium. cov ntaub ntawv.
3. Cov thermal shock kuj yuav tsum tau txhim kho
Qhov sib ntxiv ntawm monoclinic ZrO2 tuaj yeem txhim kho cov thermal shock tsis kam ntawm chrome corundum cib zoo. Txawm li cas los xij, cov thermal poob siab tsis kam ntawm chrome corundum cib tseem tsis zoo, thiab qhov tshwm sim ntawm tev thiab tawg feem ntau tshwm sim hauv kev siv, uas cuam tshuam rau kev siv gasifier kom zoo. Yog li ntawd, nws yog ib qho tsim nyog los ntxiv dag zog rau cov kev tshawb fawb ntsig txog los txhim kho cov thermal shock resistance ntawm high chromium bricks.
4. Txo cov pa phem rau ib puag ncig
Vim tias Cr2O3 nyob rau hauv chrome corundum bricks yuav oxidized rau Cr2O3 lom nyob rau hauv tej yam kev mob, polluting ib puag ncig. Yog li ntawd, yuav ua li cas tswj kev tsim cov CrO3 hauv cov txheej txheem ntawm kev tsim thiab siv, thiab ntxiv dag zog rau kev rov ua dua ntawm cov ntaub ntawv siv thiab kev kho cov khoom pov tseg kom raug, kom txo tau cov pa phem rau ib puag ncig, yog ib qho teeb meem tshwj xeeb uas tsim nyog tau txais kev saib xyuas.
