Lub circulating fluidized txaj boiler yog nyob rau hauv lub lag luam, thiab cov khoom nyob rau hauv lub boiler rauv yog nyob rau hauv lub circulating flow xeev. Ntawm lawv, cov ntaub ntawv uas muaj roj, roj tshauv, limestone thiab lawv cov tshuaj tiv thaiv cov khoom yog ib feem ntawm sab nraud ncig nyob rau hauv cov txheej txheem kev ncig, uas yog, nyob rau hauv lub kaw voj voj voog ntawm lub cub tawg - cyclone separator - rov qab valve - rauv, lawv yog nyob rau hauv. ib tug tas mus li high-ceev ncig fluidizing xeev; Ib feem ntawm nws yog kev ncig sab hauv, uas yog, cov khoom siv nrog cov khoom loj dua poob rov qab rau hauv qhov cub hauv qab qhov kev txiav txim ntawm lub ntiajteb txawj nqus. Yog tias kev xaiv cov khoom siv hluav taws xob thiab cov khoom siv tiv thaiv tsis haum, kev tsim kho zoo tsis siab, thiab qhov cub zoo tsis yog raws li qhov yuav tsum tau ua, nws yuav cuam tshuam rau kev ua haujlwm ntawm CFB boiler.
1, hnav-resistant refractory castable tsim
Castable tsim tsom rau tus pin vuam, asphalt txhuam, dej sib tov, pwm kho, kev co, tso tawm kev tiv thaiv, kev ruaj ntseg loj, ntsuas cov ntsiab lus raug thiab lwm yam txuas, nruj raws li cov kev cai ntawm cov khoom lag luam thiab cov chaw boiler.
1) Pin, ntsia thawv installation
Ua ntej dej siab, cov pins knocked tawm hauv cov txheej txheem ntawm kev thauj mus los thiab kev teeb tsa thiab kev sib koom ua ke ntawm cov cua sov saum npoo yuav tsum tau kho, thiab cov pins yuav tsum tau ua kom ntev thiab welded ntawm qhov chaw nres nkoj, qhov chaw nres nkoj rov qab, qhov chaw nres nkoj cua. thiab qhov inflection point ntawm sab sauv ntawm lub cub tawg kom ntseeg tau tias cov pins yog teem raws li tus tsim ntom. Ua ntej nchuav, siv 1 txheej ntawm asphalt xim nrog thickness> 1mm rau tag nrho cov khoom siv hlau, rau tes thiab lwm yam hlau los yog ntaub qhwv nrog cov ntaub ntawv uas tuaj yeem hlawv.
2) Cov khoom xyaw, kev faib dej, kev sib xyaw ua ke
Cov khoom xyaw yuav tsum tau hnyav thiab dej faib nruj raws li qhov yuav tsum tau ua ntawm cov khoom siv tshwj xeeb ntawm cov chaw tsim khoom, thiab kev ntsuas yuav tsum raug. Cov dej uas siv los nplawm castable yog dej huv (xws li dej haus), nrog rau pH ntawm 6 mus rau 8. Ntxiv cov khoom siv thiab dej ua tib zoo saib xyuas qhov kev txiav txim thiab sib tov thiab sib tov lub sij hawm, tsis txhob tso dej ntxiv ntawm qhov siab, tsis txhob tso cai ua ntej lossis ncua sijhawm sib tov, cov dej yuav tsum tsis txhob muab ntxiv rau ib qho chaw, cov castable yuav tsum tau tov tag nrho. Nws yog ib qho tsim nyog yuav tsum ntxiv cov hlau fiber ntau hauv cov txheej txheem ntawm kev ntxiv dej sib tov, thiab yuav tsum tsis txhob muab tso rau hauv pawg. Tom qab lub nplawm castable uas ua tau raws li qhov xav tau yog nchuav tawm, nws raug tshem tawm tam sim ntawd. Txawm hais tias lub castable raug tshem tawm los yog tsis tom qab nchuav tawm ntawm lub thoob, nws tsis raug tso cai rov qab mus rau lub thoob kom rov ua dua. Tom qab txhua qhov kev tsim kho, lub thoob yuav tsum tau muab ntxuav kom huv hauv lub sijhawm los npaj rau kev siv tom ntej; Sau cov dej ntxiv rau cov khoom xyaw, sib tov lub sijhawm thiab lwm cov ntaub ntawv.
