Boilers siv nyob rau hauv cov cua kub loj, raws li txoj cai, yog tsim tsis muaj ib tug shielding txheej. Qhov no yog vim lub fact tias lawv yog tsim nyob rau hauv raws li qhov tsis muaj ntawm chav boiler. Lub hauv paus ntawm lub boiler ua hauj lwm raws li ib tug tiv thaiv txheej thiab yog tsim los ntawm cov ntaub ntawv uas muab cov yam ntxwv tsim nyog.
Ntau yam
Lub hom phiaj tseem ceeb ntawm cov txheej txheem tiv thaiv yog txhawm rau txo qis cov cua sov thiab qhov kev pheej hmoo ntawm kev kub nyhiab rau cov neeg ua haujlwm, thiab cov nqi hluav taws xob kuj txo. Qhov tseem ceeb tshwj xeeb yog muab rau cov khoom siv los tsim cov hauv ob sab phlu, thiab kev siv tshuab tsim. Muaj ntau lub tswv yim yooj yim, txhua tus xaiv ib tus zuj zus thiab muaj kev ua haujlwm siab:
- Lub boiler hauv ob sab phlu yog ua los ntawm lub teeb yuag pob zeb, uas muaj thermal rwb thaiv tsev. Nrog kev pab ntawm chromite loj thiab cov phaj tshwj xeeb, txheej txheej yog tsim.
- Cov txheej txheem thav duab suav nrog peb txheej: pob zeb hauv av, pob zeb diatomaceous thiab fireclay pob zeb.
- Hav muajtxwv tsis pub dhau thiab tsuas yog tsim nyog rau chav boiler nrog qhov kub siab tshaj plaws ntawm 800 degrees. Lub txheej txheej yog cib liab, txheej sab hauv yog refractory brickwork.

Bricking ntawm cov dej kub boilers yog cov txheej txheem ua haujlwm hnyav uas yuav tsum tau ua raws li thev naus laus zis thiab xaiv cov khoom kom raug. Cov khoom sib xyaw ua ke yog tsim los ntawm corundum, carbundum lossis chromite hauv paus. Cov iav ua kua feem ntau ua raws li kev khi hauv paus. Tus nqi ntawm cov khoom tsim nyob ntawm qhov chaw yuav tsum tau kho thiab qhov yuav tsum tau thickness.
Cov muaj pes tsawg leeg siv rau saum npoo yog npog nrog cov mesh tshwj xeeb ua los ntawm cov khoom siv refractory. Sealing txheej yog nqa tawm nrog magnesite, asbestos lossis fireclay hmoov. Nws yuav tsum raug sau tseg tias txheej tuaj yeem ua tau yog tias qhov loj tseem tsis tau tawv.
Yam uas koj yuav tsum paub
Bas alt fiber, uas muaj qhov kub thiab txias, yog siv los tsim cov rwb thaiv tsev thermal.
Qee zaum, nws dhau los ua qhov tsim nyog rau qee qhov nteg lub boiler. Txo qhov poob ntawm thermal zog thiab ua kom muaj kev nyab xeeb ntawm kev saib xyuas cov neeg ua haujlwm yog ua tau vim qhov ua tiav ntawm lub qhov rooj ntawm cov qauv. Nyob rau hauv rooj plaub no, nws yuav tsum tau them sai sai rau qhov kub thiab txias thaum lub sij hawm txias.
Kho lub hauv ob sab phlu ntawm lub boilers pib nrog lub dismantling ntawm cov kav dej, thaum nws yog ntshaw kom txuag lub hauv paus ntawm cov qauv rau yav tom ntej siv. Nyob rau hauv lub xub ntiag ntawmCov cheeb tsam tsis sib xws ntawm cov ntxaij vab tshaus thiab cov kav dej tuaj yeem siv nrog ib txheej ntawm cov rwb thaiv tsev kub. Kev pabcuam lub neej ntawm cov qauv tuaj yeem nce ntxiv los ntawm kev siv cov xim xim txhuas siv los ua lub tsho sab saum toj.
DKVR boilers
Cov txheej txheem ntawm cov koob no yog tsim los xyuas kom muaj kev npaj cov dej kub thiab cua sov. Lawv tsim saturated chav thiab feem ntau siv nyob rau hauv qhov cua tshuab. Cov qauv tsim muaj cov yam ntxwv tshwj xeeb hauv daim ntawv ntawm cov kav dej ntsug thiab ob lub nruas. Boilers ntawm hom no muaj ntau yam zoo:
- dav zog ntau;
- siv txhua yam ntawm lub zog, suav nrog roj thiab roj;
- automated system ua haujlwm;
- kev sib dhos ntawm cov qauv tuaj yeem nqa tawm hauv chav boiler, tsis tas yuav rhuav tshem cov phab ntsa;
- Bricking ntawm DKVR boilers yog tsim los ntawm cov ntaub ntawv tsim nyog rau hom kev npaj ua haujlwm;
- kev ntseeg siab ntawm aerodynamic thiab hydraulic system ua kom muaj kev ua haujlwm siab.
Boiler hauv ob sab phlu: technology
Ib kauj ruam yuav tsum ua ua ntej cib yog qhov ntsuas hydraulic ntawm cov boilers. Tom ntej no, lub hauv ob sab phlu ntawm lub boiler nto thiab cov txheej txheej yog nqa tawm. Cov ntaub ntawv hauv ob sab phlu siv yuav tsum yog refractory thiab fireclay hmoov, xuab zeb thiab av nplaum yuav tsum tau kom huv sieved ua ntej siv. Cement, refractory thiab av nplaum liab yuav tsum tsis txhob muaj cov khoom txawv teb chaws, pob thiab cov khib nyiab me me.
Ua ntejthaum pib ntawm kev ua hauj lwm, nws yog ib qhov tsim nyog los npaj ib qho refractory sib tov, cov cuab yeej thiab cib ntawm tib qhov loj. Txhua kab ntawm masonry yuav tsum tau soj ntsuam nrog lub tsev theem kom tiv thaiv kev tsim ntawm kev nyuaj siab thiab bulges. Koj tuaj yeem txheeb xyuas qhov zoo ntawm kev tso cov ces kaum nrog steel square. Raws li nws tau pom tseeb, qhov tso ntawm chav boilers yog ib qho txheej txheem nyuaj uas yuav tsum tau ua raws li tag nrho cov cai thiab cov cai, yog li koj tuaj yeem ua haujlwm tsuas yog tias koj muaj kev paub thiab kev paub dhau los. Feem ntau, nws yog qhov zoo dua los tig mus rau cov kws tshaj lij, vim tias txawm tias qhov tsis zoo me me tuaj yeem ua rau muaj qhov tshwm sim loj rau yav tom ntej.
Ntse
txheej txheej insulating yuav tsum tsis muaj kab nrib pleb thiab chips. Ua ntej nteg refractory fireclay cib, nws yog sorted, cov khoom yuav tsum yog tib yam loj yam tsis muaj kev puas tsuaj. Kev siv cov pob zeb tawg lossis tawg yog nruj me ntsis txwv tsis pub, vim qhov no txo qis lub zog ntawm cov qauv. Cov npoo ntxhib kuj txo qhov nruj ntawm cov seams.
Kev daws teeb meem
Qhov tseem ceeb sib npaug yog qhov sib xyaw siv rau kev ua vaj tse. Nws yuav tsum muaj ib tug uniform qauv yam tsis muaj inclusions. Rau tso fireclay cib, ib qho kev daws teeb meem raws li av nplaum thiab fireclay hmoov yog haum. Lub degree ntawm cov roj cov ntsiab lus ntawm av nplaum txiav txim siab npaum li cas ntawm cov hmoov. Nws yog ib qho tsim nyog sau cia tias ntsev thiab dej xuab zeb tsis tuaj yeem ntxiv rau qhov sib xyaw, txawm tias cov khoom xyaw no feem ntau pom muaj nyob rau hauv mortars rau tso rau hauv qhov cub.
ThicknessQhov sib tov thaum lub sij hawm complex brickwork yuav tsum tsis pub dhau 2 hli; nrog rau ib txwm masonry, nce mus txog 3 hli yog tso cai. Cov txiaj ntsig tau txais ncaj qha yog nyob ntawm kev ua raws li cov proportions ntawm cov khoom xyaw thiab kev sib xyaw kom zoo. Qhov sib xws yuav tsum yog nruab nrab thickness. Cov tshuaj yog tov nrog dej huv xwb, qhov no guarantees tsis muaj txiv qaub thiab lwm yam impurities. Nws raug nquahu kom npaj cov muaj pes tsawg leeg hauv ib lub thawv cais, ua ntej ntxuav.
Dej boiler hauv ob sab phlu: piav qhia
Ua ntej pib ua haujlwm, tag nrho cov khoom siv yuav tsum tau ntxuav cov tee ntawm cov tshuaj, corrosion thiab paug. Cov ntsiab lus kev sib txuas ntawm qhov cuab lub zog yog txuas nrog ib txoj kab uas hla ntawm 2 hli los yog welded siv hluav taws xob vuam. Kev siv cov txhuas thiab tooj liab hlau yog qhov tsis xav tau.
Bitumen yog siv rau hauv ib txheej txawm ntawm qhov kev txhawb nqa thiab kho cov ntsiab lus tsim nyog los ntxiv dag zog rau cov pob zeb.
Rau qhov tsim ntawm formwork, softwood yog siv, tshwj tsis yog larch. Cov sab uas nyob ib sab ntawm lub pob zeb tov yog ua tib zoo ua tiav thiab npaj. Nws tuaj yeem siv cov ntawv los yog av nplaum nrog cov yas siab kom kaw cov kab nrib pleb hauv formwork. Ob chav formwork yog tsim rau nteg ib tug ntsug nto los yog ib tug kaum sab xis ntawm 40 degrees. Nws raug nquahu kom npog cov ntoo saum npoo nrog cov roj nplua nyeem kom tsis txhob muaj qhov adhesion rau pob zeb. Kev daws cov dej thiab cov roj ntxhia tuaj yeem siv los ua cov roj nplua nyeem.
Kilns thiab boilers hauv kev lag luam niaj hnub no tseem nyobirreplaceable khoom, yog li feem ntau yuav tsum tau kho thiab modernization ntawm cov qauv. Tsis tas li ntawd, lub pob zeb ntawm lub boiler yuav tsum tau ua thiab, yog tias tsim nyog, hloov cov ntsiab lus uas ua tsis tiav.
