Coke qhov cub regeneratorchecker cibyog ib feem tseem ceeb ntawm lub qhov cub coke, thiab lawv txoj kev ncaj ncees yog qhov tseem ceeb rau kev ua haujlwm ntawm lub qhov cub coke. Txawm li cas los xij, thaum lub sijhawm ua haujlwm tiag tiag, checker cib puas tshwm sim ib ntus, cuam tshuam rau kev tsim khoom thiab kev ruaj ntseg ntawm coke qhov cub. Tsab ntawv xov xwm no yuav ua qhov kev tshuaj xyuas qhov tob ntawm qhov ua rau thiab cov txheej txheem ntawm kev puas tsuaj rau cov cib no hauv coke cub regenerators los ntawm kev xav.
Qhov ua rau kev puas tsuaj rau cov pob zeb checkered feem ntau suav nrog cov hauv qab no:
(1) Kub-kub oxidation: Thaum lub sij hawm ua hauj lwm ntawm lub coke qhov cub regenerator, cov khoom refractory nyob rau saum npoo ntawm lub checker cib yog nquag oxidation cov tshuaj tiv thaiv vim lub sij hawm ntev raug rau kub kub, ua rau cov qauv xoob, txo lub zog. , thiab kev puas tsuaj.
(2) Kev puas tsuaj cua sov: Thaum lub sijhawm pib thiab kaw cov txheej txheem ntawm lub qhov cub coke, qhov kub ntawm lub tshuab hluav taws xob yuav hloov pauv loj heev, ua rau muaj kev ntxhov siab thermal, uas yuav ua rau micro-cracks hauv cov checker cib. Raws li lub sij hawm dhau mus, cov micro-cracks yuav maj mam nthuav, nws thiaj li ua rau tsis ua hauj lwm ntawm cov checker refractory bricks. Cov cib tawg.
(3) Tshuaj yaig: Thaum lub sij hawm tsim cov coke ncu, qee cov roj corrosive, xws li hydrogen sulfide, sulfur dioxide, thiab lwm yam. Cov pa roj carbon monoxide no yuav ua rau cov khoom siv hluav taws xob tiv thaiv hluav taws kub, ua rau muaj kev puas tsuaj rau cov cib.
(4) Mechanical hnav: Thaum lub sijhawm ua haujlwm ntawm lub qhov cub coke, airflow, coke, thiab lwm yam yuav ua rau yaig thiab hnav ntawm cov checker refractory hluav taws cib. Nyob rau lub sijhawm ntev, cov cim ntawm kev hnav yuav tshwm rau ntawm qhov chaw ntawm cov khoom siv refractory cib, uas yuav ua rau muaj kev puas tsuaj loj heev.
Qhov kev puas tsuaj ntawm cov khoom siv hluav taws xob hluav taws xob feem ntau suav nrog peb yam: thermal kev puas tsuaj, tshuaj yaig thiab kev siv tshuab. Ntawm lawv, thermal kev puas tsuaj yog lub ntsiab yog vim li cas rau kev puas tsuaj ntawm checker bricks. Thaum lub sij hawm tus txheej txheem pib thiab nres lub qhov cub coke, qhov kub ntawm lub regenerator hloov sai heev, ua rau thermal stress nyob rau hauv cov hniav nyiaj hniav kub cib. Thaum lub thermal stress tshaj lub zog ntawm bricks, kev puas tsuaj yuav tshwm sim. Tsis tas li ntawd, kev siv tshuaj lom neeg thiab cov khoom siv kho tshuab kuj tseem muaj qee yam cuam tshuam rau kev puas tsuaj ntawm cov checker refractory bricks.
Txhawm rau txo qhov kev puas tsuaj ntawm cov pob zeb checker, cov kev ntsuas hauv qab no tuaj yeem ua:
(1) Ua kom zoo rau kev pib thiab nres cov txheej txheem ntawm lub qhov cub coke, txo qhov kub thiab txias, thiab txo qhov cuam tshuam ntawm thermal stress ntawm lub checker hluav taws cib.
(2) Txhim kho lub sealing ntawm lub qhov cub coke, txo cov tiam thiab diffusion ntawm corrosive gases, thiab txo qhov kev puas tsuaj rau cov checker refractories bricks tshwm sim los ntawm cov tshuaj yaig.
(3) Txhim kho cov khoom siv thiab kev tsim cov txheej txheem ntawm cov cib no los txhim kho cov hnav tsis kam thiab corrosion kuj ntawm cov cib.
(4) Tsis tu ncua tshuaj xyuas thiab kho cov pob zeb checkered, nrhiav thiab daws cov teeb meem kev puas tsuaj raws sijhawm, thiab zam kev nthuav dav ntawm kev puas tsuaj.
Hauv cov ntsiab lus, cov laj thawj thiab cov txheej txheem ntawm kev puas tsuaj rau cov pob zeb checker hauv coke qhov cub regenerators yog qhov nyuaj thiab ntau yam, thiab xav tau kev tshuaj xyuas thiab cov lus teb los ntawm ntau yam. Los ntawm kev siv cov kev ntsuas tsim nyog thiab kev siv tshuab, qhov kev puas tsuaj ntawm cov hluav taws kub hluav taws tuaj yeem raug txo kom zoo thiab cov khoom siv hluav taws xob thiab kev ruaj ntseg ntawm coke ncu tuaj yeem txhim kho.
