Circulating fluidized txaj boiler (CFB boiler) tau dhau los ua kev txhim kho ntawm kev siv tshuab huv huv vim nws qhov zoo ntawm ntau yam kev sib xyaw ua ke, pheej yig desulfurization, tsis muaj kuab paug tawm thiab siab combustion tus nqi.
Txawm li cas los xij, hauv cov txheej txheem kev ua haujlwm tiag tiag, kev hnav ntawm CFB boiler tau dhau los ua qhov teeb meem tseem ceeb uas cuam tshuam ncaj qha rau nws txoj kev lag luam thiab kev nyab xeeb, ntxiv rau, lub boiler rauv, ignition cua duct, refeeder thiab lwm qhov chaw ntawm lub hauv ob sab phlu refractory poob, tab sis kuj. cuam tshuam rau kev ua haujlwm li qub ntawm boiler.
1 Kev tsim kho txheej txheem
Kev tsim kho ntawm qhov chaw hnav-resistant refractory hauv ob sab phlu yuav tsum tau txiav txim siab raws li nws lub peev xwm nqa, qhov loj me, lub sijhawm, kev nyab xeeb thiab lwm yam kev mob, thiab tsis tuaj yeem ua qauv sib koom ua ke. Txawm li cas los xij, nws yog ib txwm ua tau rau prefabricate hauv ob sab phlu ua ntej lub boiler los ua ke kom txo tau tus nqi ntawm high-altitude ua hauj lwm tom qab cov khoom nyob rau hauv qhov chaw.
Piv txwv li, lub boiler lub ignition cua duct, steering flue, cyclone separator, refeeder, slag drainer, thiab lwm yam., pab pawg neeg tuav lub interface ib feem tom qab installation. Rau lub convection tube bundle ntawm lub cua sov saum npoo, vim qhov yuav tsum tau ua qhov kev ntsuam xyuas hydraulic, nws tsis raug tso cai los npog cov yeeb nkab saum npoo ua ntej, qee zaum txhawm rau kom ncav cuag lub sijhawm tsim kho, koj tuaj yeem tau txais kev pom zoo los ntawm cov yeeb nkab. boiler soj ntsuam department, ua ntej ua qhov kev ntsuam xyuas huab cua nruj, qhov uas yuav tsum tau lined nrog cov anti-coj txheej nyob rau hauv lub ua ke nto rau kerosene to tshuaj ntsuam xyuas, thiab paub meej tias tus tsim nyog yuav ua tau lub hauv ob sab phlu kev tsim ua thawj zaug.
Kev tsim kho hauv ob sab phlu ntawm lub txaj ntaub cua phaj yog ib qho teeb meem ntau dua, vim tias muaj ntau lub cowls, qhov loj ntawm lub hauv ob sab hauv yuav tsum yog qhov tseeb, thiab cov hauv ob sab hauv yuav tsum tiv thaiv kom tsis txhob thaiv cov tuyole, yog li lub cowl yuav tsum tau qhwv. nrog daim kab xev ua ntej kev tsim kho, thiab hauv ob sab phlu thickness yuav tsum tau cim, thiab ua tib zoo sau cov khoom txheej, thiab ramming nrog cov cuab yeej me me.
2. Kev xaiv cov khoom siv
1) Castable
(1) Tus nqi ntawm castable yog pheej yig dua, kev tsim kho zoo yog yooj yim rau kev tswj, thiab nws yog haum rau kev tsim loj, tab sis nws hnav tsis kam thiab kho tej yam kev mob tsis zoo li ramming cov ntaub ntawv.
(2) Kev tsim kho castable ramming yuav tsum nyob deb li deb tau hauv av, txhawm rau txuag cov qauv, ua raws li sab, yog tias nws yog lub tog raj kheej, nws yuav tsum tau dov. On-site prefabrication ua hauj lwm yuav tsum xav txog qhov kev sib hloov ntawm lub Cheebtsam, uas yog txwv los ntawm qhov hnyav ntawm cov khoom siv, yog hais tias tsuas yog ib feem ntawm prefabrication, nws yuav tsum tau muab tso tseg rau tom qab ua hauj lwm.
(3) Cov dej-cement piv ntawm castable yog qhov tseem ceeb rau qhov zoo thiab yuav tsum tau tswj nruj me ntsis.
