Emikhakheni yezimboni eshisa kakhulu kanye nengcindezi ephezulu, ukukhethwa kwezinto kubalulekile ekuphepheni kwemishini kanye nokusebenza kahle. I-T91 kanye ne-P91, njengezinsimbi ezimbili ezivame ukusetshenziswa ezimelana nokushisa kwe-martensitic, zisetshenziswa kabanzi ekukhiqizeni ugesi, i-petrochemical, kanye nezimboni ezihlobene. Nakuba amagama azo afana futhi ukwakheka kwamakhemikhali kusondelene, izici zazo zokusebenza kanye nezimo zokusetshenziswa zibonisa umehluko omkhulu.

Umehluko Oyisisekelo PhakathiI-T91futhiI-P91

Izincazelo kanye namazinga

I-T91 (T91 Tube) iyinsimbi yezinga lamapayipi esetshenziswa kakhulu ekukhiqizeni amashubhu ebhoyila, amashubhu e-superheater kanye ne-reheater, kanye nezinye izingxenye zamashubhu. Ihambisana ne-I-ASME SA-213amazinga.

P91 (Ipayipi le-P91) iyinsimbi yezinga lamapayipi esetshenziselwa ukukhiqiza imigqa eyinhloko yomusi, izihloko, nezinye izingxenye zokucindezela. Lokhu kulandelayoI-ASME SA-335amazinga.

Umehluko Wokwakheka Kwamakhemikhali

Zombili izinsimbi zabelana ngokwakheka kwamakhemikhali okufanayo, ngezinguquko ezincane:

Okuqukethwe kwe-aluminium: I-T91 ngokuvamile inokuqukethwe kwe-aluminium okuphansi (≤0.04%), kuyilapho i-P91 ingaba namazinga aphezulu kancane (≤0.06%)

Inqubo Yokukhiqiza: I-T91 ivame ukukhiqizwa njengepayipi elingenamthungo, kanti i-P91 ingakhiqizwa njengepayipi elingenamthungo noma elihlanganisiwe

Umehluko Wezakhiwo Zemishini

Izidingo zamandla: I-P91 inezidingo zamandla aphezulu kancane ukuze ivumelane nobubanzi obukhulu kanye nezindonga ezijiyile

Ukuqina komthelela: I-P91 ngokuvamile inezidingo eziqinile zokuqina komthelela

Ukwelashwa ngokushisa: Kokubili kudinga ukwenziwa kube ngokwejwayelekile kanye nokulungiswa, kodwa amapharamitha athile angahluka ngokuya ngobukhulu besigaba

Izindawo Zokufaka Isicelo

Izicelo Eziyinhloko ze-T91

Amashubhu e-Superheater kanye ne-reheater kuma-boiler esitshalo samandla

Izinhlelo zamapayipi ezinokushisa okuphezulu nezinomfutho ophezulu

Izinqwaba zamashubhu okushintshanisa ukushisa

Izingxenye ze-Tubular ezisebenza ku-593-649°C

Izicelo Eziyinhloko zeI-P91

Imigqa emikhulu yomusi kanye nemigqa yokushisa kabusha eshisayo ezitshalweni zikagesi

Ama-header nama-manifold anezinga lokushisa eliphezulu, anezinga lokushisa eliphezulu

Amapayipi kumayunithi e-petrochemical hydrocracking

Amapayipi esistimu yamandla enuzi

Izingxenye zokucindezela ezinodonga olujiyile ezisebenza ku-593-649°C

Izinto Okufanele Uzicabangele Zokukhetha

Izimo zokusebenza: Izinga lokushisa, ingcindezi, kanye nokugqwala kwemidiya

Uhlobo lwengxenye: Izingxenye zokushintshanisa ukushisa ngamapayipi, ama-header, noma amashubhu

Izidingo zokukhiqiza: Ukushibilika kanye nokwakheka kahle

Izici zomnotho: Izindleko zokuqala kanye nezindleko zomjikelezo wokuphila

Ukuthobela imithetho: Kumelwe kuhlangatshezwane nezindinganiso kanye namakhodi afanele embonini

Izitayela Zokuthuthukiswa

Ngokuthuthuka kobuchwepheshe bokukhiqiza amandla obusezingeni eliphezulu nobusezingeni eliphezulu, ububanzi bokusetshenziswa kwezinsimbi ze-T91/P91 buyaqhubeka nokukhula. Ucwaningo lwamanje lugxile kulokhu:

Ukuthuthukisa ngokwengeziwe amandla okuhamba okushisa okuphezulu kwesikhathi eside

Ukuthuthukisa ukuzinza kwesikhathi eside kwamalunga ahlanganisiwe

Ukuthuthukisa izinqubo zokukhiqiza ezingabizi kakhulu

Ukuhlola ukusebenza ezinhlelweni zomjikelezo we-carbon dioxide

Nakuba i-T91 ne-P91 zinokwakheka kwamakhemikhali okufanayo, zinomehluko ohlukile ezimweni zokusetshenziswa, izidingo zokusebenza, kanye nezindinganiso zokukhiqiza. Ukukhetha nokusetshenziswa okufanele kwalezi zinto kubalulekile ekuqinisekiseni ukusebenza okuphephile kanye nokwandisa impilo yesevisi yemishini eshisa kakhulu, enomfutho ophezulu. Onjiniyela kufanele benze izinqumo ezinolwazi ngokusekelwe ezimweni ezithile zokusetshenziswa, izidingo zokuklama, kanye nezindinganiso zemboni.
