Is Nrias teb, ua ib lub teb chaws uas muaj kev lag luam loj hlob sai tshaj plaws hauv ntiaj teb, muaj kev lag luam tsim khoom boiler uas vam meej vim nws qhov kev thov hluav taws xob nce ntxiv thiab kev nthuav dav ntawm kev lag luam. Kev lag luam no yog tswj hwm los ntawm ob peb lub tuam txhab loj uas muab cov khoom siv tseem ceeb rau cov khoom tseem ceeb xws li kev tsim hluav taws xob, petrochemicals, thiab chiv. Hauv kev tsim cov boilers no, cov kav hlau chrome-molybdenum alloy steel uas ua raws li tus qauv ASTM A335 yog qhov tseem ceeb "cov kab cawm siav." Lawv qib kev siv yog qhov qhia ncaj qha ntawm kev lag luam lub zog thiab kev txawj ntse.

Cov Chaw Tsim Khoom Boiler Ua Ntej hauv Is Nrias teb

1.Bharat Hnyav Hluav Taws Xob Limited (BHEL)

Ib lub tuam txhab lag luam uas yog lub xeev thiab yog tus thawj coj tsis muaj kev sib cav hauv Is Nrias teb cov khoom siv hluav taws xob, BHEL tsim ntau yam boilers, los ntawm cov chaw lag luam me me mus rau cov loj rau cov chaw tsim hluav taws xob supercritical thiab ultra-supercritical. Nrog rau cov haujlwm thoob plaws Is Nrias teb thiab thoob ntiaj teb, BHEL qhov kev thov rau cov ntaub ntawv zoo yog qhov loj heev.

2.Ua ib lub tuam txhab muab kev daws teeb meem rau lub zog thiab ib puag ncig, Thermax yog lub tuam txhab uas muaj npe nrov rau nws cov tshuab boiler ua haujlwm tau zoo thiab huv si. Nws cov khoom lag luam suav nrog cov boiler siv thee, roj siv, biomass siv, thiab cov boiler rov qab siv cua sov pov tseg, uas pabcuam rau ntau yam kev lag luam.

3.Larsen & Toubro (L&T) - Boiler Division

Ua ib lub tuam txhab loj tshaj plaws hauv Is Nrias teb, L&T lub chaw ua haujlwm boiler tuav txoj haujlwm tseem ceeb hauv kev lag luam boiler rau cov khoom siv hluav taws xob thiab kev lag luam loj. Nws lub peev xwm ua haujlwm engineering zoo thiab kev ua tiav ntawm cov phiaj xwm loj ua rau nws yog tus neeg tseem ceeb.

4.Cethar Vessels Limited

Ib lub chaw tsim khoom tshwj xeeb boiler, Cethar Vessels muaj lub koob npe nrov hauv kev lag luam fais fab hauv Is Nrias teb, tshwj xeeb tshaj yog rau cov boilers nruab nrab mus rau loj.

Daim Ntawv Thov thiab Kev Siv Khoom ntawm A335 Alloy Steel Pipes

1. Vim li cas ho xaiv cov kav dej A335?

Cov kav hlau sib xyaw ua ke raws li tus qauv A335 (feem ntau hu ua qib zoo li P91, P92, P11, P22) yog siv dav hauv cov ntu tseem ceeb ntawm cov boilers vim lawv lub zog kub zoo heev, tiv taus kev nkag, thiab tiv taus oxidation. Cov ntawv thov tseem ceeb suav nrog:

Cov Tshuab Ua Kub Hnyav: Qhov twg cov pa roj saturated raug cua sov rau cov pa roj superheated, ua rau cov kav dej kub dhau.

Cov Tshuab Ua Kom Sov Dua: Cov uas ua kom cov pa sov dua tom qab nws ua haujlwm hauv lub turbine kom txhim kho kev ua haujlwm.

Cov Kav Dej Loj: Thauj cov pa dej kub thiab siab los ntawm lub boiler mus rau lub turbine.

2. Kev Tshawb Fawb Txog Cov Qauv Siv Khoom

Kev siv cov kav hlau A335 los ntawm cov chaw tsim khoom boiler hauv Is Nrias teb yog qhov tseem ceeb thiab ua rau pom cov yam ntxwv hauv qab no:

Ncaj Qha Sib Piv Rau Qhov Loj thiab Qib ntawm Qhov Project: Lub boiler loj ntawm lub chaw tsim hluav taws xob supercritical (piv txwv li, 660 MW unit) yuav xav tau ntau pua lossis txawm tias ntau txhiab tonnes ntawmA335 P91/P92cov kav dej. Qhov sib txawv, lub boiler me me rau kev lag luam tsuas yog siv ob peb tonnes xwb.

Kev Siv Cov Khoom Siv Zoo Dua: Thaum Is Nrias teb hloov mus rau kev siv tshuab ua haujlwm zoo dua, txo qis kev tso pa phem supercritical thiab ultra-supercritical, qhov kev thov rau cov qib ua haujlwm siab xws li A335 P91 thiab P92 tab tom loj hlob sai. Cov ntaub ntawv no tso cai rau cov pa dej siab dua (kub thiab siab), yog li ua rau cov nroj tsuag ua haujlwm tau zoo dua.

Kev vam khom rau Ob qho tib si Ntshuam thiab Kev Tsim Khoom Hauv Tebchaws: Qee lub tuam txhab hlau Is Nrias teb (piv txwv li, ISMT) tuaj yeem tsim qee qib A335 (xws li P11, P22). Txawm li cas los xij, rau cov qib uas xav tau kev siv tshuab ntau tshaj plaws xws li P91 thiab P92, tseem muaj qee qib kev vam khom rau kev xa khoom los ntawm Tuam Tshoj, Tebchaws Europe, thiab Nyiv Pooj vim yog qhov zoo thiab kev txiav txim siab txog peev xwm. Qhov no ua rau kev tswj hwm cov khoom siv thiab kev tswj hwm tus nqi yog qhov nyuaj rau cov neeg ua boiler.

Kev Xav Tau Hauv Kev Ua Lag Luam: Kev siv khoom muaj feem cuam tshuam nrog Is Nrias teb txoj kev nqis peev hluav taws xob. Kev xav tau cov kav dej A335 nce siab thaum lub sijhawm uas tsoomfwv muaj zog thawb kom muaj peev xwm ntxiv hluav taws xob los ntawm thee lossis kev nqis peev hauv kev lag luam muaj zog.

Cov chaw tsim khoom boiler ua lag luam hauv Is Nrias teb, xws li BHEL, Thermax, thiab L&T, yog cov neeg ua si tseem ceeb hauv kev lag luam boiler thoob ntiaj teb. Lawv txoj kev loj hlob yog txuas nrog lub zog yav tom ntej ntawm Is Nrias teb thiab lub ntiaj teb. A335 alloy steel kav, ua cov khoom siv tseem ceeb rau lawv cov khoom tseem ceeb, pom kev siv uas tsis yog tsuas yog qhov ntsuas ntawm cov tuam txhab no qhov kev lag luam tab sis kuj yog qhov ntsuas rau Is Nrias teb txoj kev tsim kho vaj tse thiab kev nce qib thev naus laus zis. Saib rau pem hauv ntej, kev nrhiav cov thev naus laus zis siv hluav taws xob zoo, huv si yuav tsav tsheb kev loj hlob txuas ntxiv hauv kev thov rau cov kav dej A335 qib siab.
