- Ukukhethwa kwezinto zeama-heaters amapayipiithinta ngokuqondile impilo yabo yesevisi, ukusebenza kahle kokushisisa, nokuphepha, futhi idinga ukwahlulelwa ngokugcwele ngokusekelwe ezicini ezibalulekile ezifana nezici zendlela yokusebenza, izinga lokushisa, ingcindezi, nokugqwala.
1. Izici ezibalulekile ezithinta ukukhethwa kwezinto
Izici ze-work medium:
Ukuthi i-medium iyagqwala (njengezixazululo ze-acid-base, amanzi olwandle, uketshezi lwemfucuza yamakhemikhali, njll.);
Ukuthi i-medium iqukethe ukungcola (okufana nezinhlayiya, i-sediment, njll., engabangela ukuguga);
Ukuthi i-medium iyibanga lokudla noma ibanga lemithi (kufanele ihlangabezane nezidingo zokuhlanzeka futhi kungabikho imvula).
Izinga lokushisa lokusebenza:
Ukusebenza kokumelana nokushisa okuphezulu kwezinto ezihlukahlukene kuyahlukahluka kakhulu ekamelweni lokushisa (≤ 100 ℃), izinga lokushisa eliphakathi (100-600 ℃), kanye nezinga lokushisa eliphezulu (> 600 ℃).
ingcindezi yokusebenza:
Ingcindezi ephansi (≤ 1MPa), ingcindezi emaphakathi (1-10MPa), ingcindezi ephezulu (>10MPa), impahla kumele ihlangabezane nezidingo zamandla emishini ngaphansi kwengcindezi ehambisanayo.
2. Izinto ezijwayelekile kanye nezimo ezisebenzayo
Insimbi engagqwali (evame ukusetshenziswa kakhulu)
Ihlukaniswe ngamamodeli afana ne-304, 316, 310S, njll., ukumelana nokugqwala nokumelana nokushisa okuphezulu kuyathuthukiswa ngokulandelana:
304 insimbi engagqwali:ukumelana nokugqwala okuvamile (njengamanzi, umoya, i-asidi ebuthakathaka ne-alkali), izindleko ezimaphakathi, ezifanele ukushisisa amanzi kampompi, amanzi avamile ezimbonini, umoya ocindezelwe, njll., izinga lokushisa lokusebenza ≤ 600 ℃, ingcindezi ≤ 10MPa.
316 insimbi engagqwali:equkethe i-molybdenum element, enokumelana nokugqwala okungcono kune-304, ingamelana namanzi olwandle, izixazululo ezinosawoti ophansi, i-sulfuric acid ehlanjululwe, njll., ifanele indawo yasolwandle, imidiya yokugqwala yamakhemikhali, izinga lokushisa ≤ 800 ℃.
310S insimbi engagqwali:ukumelana nezinga lokushisa eliphezulu (≤ 1200 ℃), ukumelana ne-oxidation okuqinile, kulungele izimo zokufudumeza ezifana negesi yokushisa ephezulu yokushisa nosawoti oncibilikisiwe, kodwa ukumelana nokugqwala okuphansi kancane ku-316.
Insimbi ye-carbon
Izindleko eziphansi, amandla okusebenza aphezulu (angakwazi ukumelana nokucindezela>20MPa), kodwa ajwayele ukugqwala (kudinga upende ovimbela ukugqwala noma ukuvikeleka kokugqwala), afanelekela kuphela imidiya engagqwali, izinga lokushisa/izinga lokushisa elimaphakathi (≤ 300 ℃), njengowoyela wenjini yokushisisa namagesi ajwayelekile asezimbonini.
3, Izinyathelo zokukhetha kanye nereferensi yecala
1. Cacisa izimfuneko eziyinhloko:
Okokuqala thola indawo ephakathi nendawo (ukugqwala/ukuhlanzeka), izinga lokushisa (izinga lokushisa legumbi/ukushisa okuphezulu), ukucindezela (umfutho ophezulu/umfutho ophansi?), bese uqondanisa izakhiwo zezinto ezibonakalayo.
2. Izibonelo zesimo esijwayelekile:
Amanzi kampompi okushisa/amanzi ezimboni ajwayelekile: 304 insimbi engagqwali (izindleko zokulinganisa kanye nokumelana nokugqwala);
Amanzi olwandle ashisisayo/amanzi angcolile anosawoti aphansi: 316 insimbi engagqwali (ayizweli ukugqwala kwe-ion ye-chloride);
Ukushisisa okugxilile kwe-hydrochloric acid/isixazululo se-alkali esiqinile: ingxubevange ye-titanium noma ingxubevange ye-Hastelloy (enezidingo eziqinile zokumelana nokugqwala);
Ukushisa kwamanzi ashisayo ebangeni lokudla: 316 insimbi engagqwali (ihlanzekile+imelana nokugqwala);
Izinga lokushisa eliphakeme lokushisisa kwegesi ye-flue (800 ℃): 310S insimbi engagqwali (imelana ne-oxidation yokushisa ephezulu)
Uma ufuna ukwazi okwengeziwe ngomkhiqizo wethu, sicelaXhumana nathi!
