Stainless hlau cua txias kav yog ib qho tseem ceeb ntawm cov condenser

Lub condenser yog ib qho ntawm cov khoom siv tseem ceeb ntawm chav turbine generator, thiab nws qhov kev ua tau zoo cuam tshuam ncaj qha rau kev ua haujlwm ntawm chav tsev. Thiab nws qhov tseem ceeb ntawm kev hloov cov cua sov - lub raj cua txias - yog ib qho tseem ceeb ntawm cov condenser, uas suav nrog ntau tshaj li ib nrab ntawm nws cov nqi tag nrho. Yog li ntawd, kev xaiv cov kav dej txias yog tus yuam sij rau kev tsim condenser.
Txij li thaum Lub Xya Hli 1958, lub ntiaj teb thawj cov yeeb nkab steel hlau tsis muaj cua txias nrog thaj tsam ntawm 5109m2 tau muab tso rau hauv kev ua haujlwm ntawm West Virginia Valley fais fab nroj tsuag hauv Tebchaws Meskas, thiab cov tuam txhab loj xws li Nyiv thiab Europe tau pib ua raws li kev cai. Raws li qhov sib txawv ntawm cov dej zoo thiab cov tshuaj chloride ion concentrations, cov qib sib txawv ntawm cov kav dej stainless hlau siv rau cov kav dej txias ntawm cov condenser. Raws li cov lus ceeb toom, 20.9 feem pua ​​​​ntawm cov condensers tau teeb tsa thiab xaj thaum xyoo 1965 thiab 1971 yog cov kav hlau tsis muaj steel siv hauv Jianghu cua txias ntauwd.
Txij thaum ntawd los, qhov kev faib ua feem ntawm tub rog tooj liab cov kav dej uas ib txwm siv dav tau txo qis los ntawm 50 feem pua ​​​​mus rau thaj tsam 30 feem pua.
Kev loj hlob loj ntawm cov tsev loj hauv tsev tau pib thaum xyoo 1980s, thiab ntau lub zog hluav taws xob tau pib nruab rau ntawm 300MW units. Shang'an fais fab nroj tsuag, Handan fais fab nroj tsuag, thiab Qitaihe fais fab nroj tsuag. Vim qhov tseeb tias kev siv cov hlau tsis huv hauv cov condensers hauv Suav teb tau pib txog 30 xyoo tom qab tshaj tawm txawv teb chaws, tib neeg muaj kev nkag siab txog qhov teeb meem no. Txawm hais tias stainless hlau yeeb nkab tau raug pov thawj nyob rau hauv kev xyaum vim nws muaj zog corrosion kuj thiab ntev kev pab cuam lub neej, vim nws thermal conductivity tsawg, lub theoretical tag nrho cov tshav kub hloov coefficient yog 6 feem pua ​​tsawg tshaj li ntawm tooj liab yeeb nkab (qhov tseeb, tag nrho cov tshav kub hloov lwm lub tsev). coefficient ntawm kev ua haujlwm mus sij hawm ntev yog zoo dua li ntawm cov yeeb nkab tooj liab). Tsis tas li ntawd, tib neeg muaj kev nkag siab me ntsis ntawm kev nthuav dav thiab kev saib xyuas, thiab cov kav dej xa tawm yog kim heev, ua rau ob peb tus neeg txaus siab rau kev pheej hmoo.
Txog tam sim no, tsuas yog ob peb 300MW units, feem ntau 300MW units thiab yuav luag tag nrho 50MW, 100MW, 125MW, thiab 200MW units tseem siv cov kav dej tooj liab thiab cov kav dej titanium me me. Tom qab ntawd tib neeg yuav xav tsis thoob seb puas muaj cov yeeb nkab steel hlau tsis zoo nrog qhov zoo ntawm qhov muaj zog corrosion kuj, lub neej ntev kev pab cuam, siab kub hloov coefficient, yooj yim thiab txhim khu kev qha installation, thiab nws cov nqi sib npaug los yog qis dua cov yeeb nkab tooj liab.
Txij li thaum ntxov xyoo 1990, peb tau ua kev tshawb fawb thiab kev sim hauv cheeb tsam no. Nyob rau hauv txoj kev xav, peb tau ua ke lub chaw soj nstuam tseem ceeb ntawm kev hloov hluav taws xob hauv Suav teb - Chemical Research Institute ntawm South China University of Technology, siv nws cov kauv zawj raj cua sov hloov txoj kev xav, ua ke nrog cov xwm txheej tshwj xeeb, rov ua qauv qhia thiab sim, thiab ua kom zoo dua cov cua txias. raj profiles haum rau ntau lub sijhawm. Qhov zoo tshaj plaws condenser nrog txias tubes - npaum stainless hlau corrugated welded raj condenser - tau tshwm sim. Nws cov kev ua tau zoo heev tau ua pov thawj dav dav hauv kev xyaum, thiab cov neeg siv feem ntau teb tau zoo. Tam sim no, peb lub tuam txhab tau tsim ntau thiab muab tso rau hauv kev ua haujlwm tshaj 60 teeb.
