Ithini indlela yokufaka isifudumezi somoya?

I-heater duct yomoya isetshenziswa kakhulu ukushisisa ukugeleza komoya odingekayo ukusuka ekushiseni kokuqala kuya ezingeni lokushisa lomoya elidingekayo, elingafika ku-850°C. Isetshenziswe kabanzi kumalabhorethri amaningi ocwaningo lwesayensi nokukhiqiza afana ne-aerospace, imboni yezikhali, imboni yamakhemikhali namanyuvesi. Ifaneleka ngokukhethekile ekulawuleni izinga lokushisa okuzenzakalelayo, ukugeleza okukhulu kanye nokushisa okuphezulu okuhlanganisiwe izinhlelo kanye nokuhlolwa kwezesekeli.

II-heater ye-air ductinezinhlobonhlobo zokusetshenziswa: ingashisisa noma iyiphi igesi, futhi umoya oshisayo okhiqizwayo womile, awunamswakama, awuhambisani, awushi, awuqhumi, awugqwali ngamakhemikhali, awungcolisi, uphephile futhi uthembekile, futhi indawo eshisayo ishisa ngokushesha (iyalawuleka).

Amafomu okufaka weizifudumezi zomoyangokuvamile zihlanganisa okulandelayo:

1. Ukufakwa kwe-Docking;

2. Ukufakwa kwe-plug-in;

3. Ukufakwa okuhlukile;

4. Izindlela zokufaka njengokufakwa kokungena. .

Abasebenzisi bangakhetha izindlela ezihlukene zokufaka ezifanele ngokusekelwe esimweni sabo sangempela. Ngenxa yobukhethekile bayo, i-casing material ye-heater duct heater ngokuvamile yenziwe ngensimbi engagqwali noma ishidi likathayela, kuyilapho izingxenye eziningi zokushisa zenziwe ngensimbi engagqwali. Ngakho-ke, lapho ukhetha, uma impahla yenziwe nge-carbon steel, kuyadingeka Iziqondiso ezikhethekile zokuqinisekisa ikhwalithi yokufaka nokuphila isikhathi eside.

Mayelana nokulawula i-heater ye-air duct, idivayisi yokuxhuma kufanele yengezwe phakathi kwefeni ne-heater ukuze kuqinisekiswe ukuthi i-heater iyaqala. Lokhu kufanele kwenziwe ngemuva kokuqala kwe-fan. Ngemva kokuba i-heater iyeka ukusebenza, isiphephetha-moya kufanele sibambezeleke isikhathi esingaphezu kwemizuzu engu-3 ukuze i-heater ingashisi kakhulu futhi yonakaliswe. Izintambo zesiyingi esisodwa kufanele zihambisane nezindinganiso ze-NEC, futhi ukusebenza kwegatsha ngalinye akufanele kudlule ku-48A.

Umfutho wegesi oshisiswe yi-heater yepayipi lomoya ngokuvamile aweqi ku-0.3kg/cm2. Uma ukucaciswa kwengcindezi kudlula lokhu okungenhla, sicela ukhethe i-heater circulation. Ukushisa okuphezulu kokushisa kwegesi nge-heater ephansi yokushisa akudluli ku-160 ° C; uhlobo lwezinga lokushisa eliphakathi alwedluli ku-260°C, kanti uhlobo lwezinga lokushisa eliphezulu aludluli ku-500°C.
