Kwicandelo lemizi-mveliso elinobushushu obuphezulu kunye noxinzelelo oluphezulu, ukukhethwa kwezinto kubalulekile kukhuseleko lwezixhobo kunye nokusebenza kakuhle. I-T91 kunye ne-P91, njengeentsimbi ezimbini ezisetyenziswa rhoqo ze-martensitic ezimelana nobushushu, zisetyenziswa kakhulu kumashishini okuvelisa umbane, i-petrochemical, kunye namashishini anxulumene nawo. Nangona amagama azo efana kwaye ukwakheka kweekhemikhali kusondelelene, iimpawu zazo zokusebenza kunye neemeko zokusetyenziswa zibonisa umahluko omkhulu.

Umahluko oPhambili phakathiT91kwayeI-P91

Iinkcazo kunye neMigangatho

I-T91 (T91 Tube) yintsimbi yodidi lweetyhubhu esetyenziselwa kakhulu ukwenza iityhubhu zebhoyila, iityhubhu ze-superheater kunye ne-reheater, kunye nezinye izinto zetyhubhu. Ihambelana neI-ASME SA-213imigangatho.

P91 (Umbhobho we-P91) yintsimbi yodidi lwemibhobho esetyenziselwa ukwenza imigca ephambili yomphunga, ii-headers, kunye nezinye izinto zoxinzelelo. Oku kulandelayoI-ASME SA-335imigangatho.

Umahluko kwiMichiza

Zombini izitena zabelana ngokwakhiwa kweekhemikhali okufanayo, kunye notshintsho oluncinci:

Umxholo we-aluminiyam: I-T91 idla ngokuba nomxholo we-aluminiyam ophantsi (≤0.04%), ngelixa i-P91 isenokuba namanqanaba aphezulu kancinci (≤0.06%)

Inkqubo yokuvelisa: I-T91 idla ngokuveliswa njengetyhubhu engenamthungo, ngelixa i-P91 inokwenziwa njengombhobho ongenamthungo okanye odibeneyo

Umahluko kwiipropati zoomatshini

Iimfuneko zamandla: I-P91 ineemfuneko zamandla aphezulu kancinci ukuze ilungele ububanzi obukhulu kunye neendonga ezityebileyo

Ukuqina kwempembelelo: I-P91 ngokubanzi ineemfuno ezingqongqo zokuqina kwempembelelo

Unyango lobushushu: Zombini zifuna ukulungiswa kunye nokulungiswa, kodwa iiparameter ezithile zinokwahluka ngokusekwe kubukhulu becandelo

Iindlela zoPhuhliso

Ngokuphucuka kwetekhnoloji yokuvelisa umbane ebaluleke kakhulu nebaluleke kakhulu, uluhlu lwezixhobo zentsimbi ze-T91/P91 luyaqhubeka nokukhula. Izifundo zophando ezikhoyo ngoku ziquka:

Ukuphucula ngakumbi amandla okuhamba kobushushu obuphezulu bexesha elide

Ukuphucula uzinzo lwexesha elide lwamalungu adibeneyo

Ukuphuhlisa iinkqubo zokuvelisa ezingabizi kakhulu

Ukuhlola ukusetyenziswa kwenkqubo yomjikelo wekhabhoni diokside

Nangona i-T91 kunye ne-P91 zabelana ngendlela efanayo yeekhemikhali, zinezahluko ezahlukeneyo kwiimeko zokusetyenziswa, iimfuno zokusebenza, kunye nemigangatho yokwenziwa. Ukukhetha kunye nokusetyenziswa ngokufanelekileyo kwezi zinto kubalulekile ekuqinisekiseni ukusebenza okukhuselekileyo kunye nokwandisa ubomi benkonzo yezixhobo ezishushu kakhulu nezinoxinzelelo oluphezulu. Iinjineli kufuneka zenze ukhetho olunolwazi ngokusekelwe kwiimeko ezithile zokusetyenziswa, iimfuno zoyilo, kunye nemigangatho yoshishino.
