Uvavanyo Lokusebenza Kakuhle Kwamandla Lokuhlaziywa Kokugquma Ubushushu Kwezixhobo Zevalvu ze-R2-R3
Olu vavanyo lwenza uhlalutyo malunga neenzuzo zokonga umbane ezifunyenweyo emva kokufakwa Ijakethi yokukhusela ubushushus kwiivalvu nezixhobo. Ngaphambi kokuhlaziywa, izinto ezisebenza ngobushushu obuphezulu zeevalvu nezixhobo zachitha amandla amaninzi obushushu ngemitha kunye ne-convection, nto leyo eyabangela ukusetyenziswa kwamandla okungasebenzi kakuhle. Okwangoku, yaphakamisa ubushushu obungqongileyo bendawo engqongileyo, nto leyo eyaphazamisa intuthuzelo yokusebenza kunye nokuzinza kokusebenza kwezixhobo. Umaleko wokufakelwa kwe-insulation ofakiweyo unokunciphisa ukuguquguquka kobushushu bezixhobo, unciphise umonakalo woxinzelelo lobushushu, kwaye unciphise izinga lokusilela kunye neendleko zokugcina. Ngokwembono yembuyekezo kutyalo-mali, igalelo lokuhlaziya linokufunyanwa kwixesha elifutshane ngokusebenzisa iinzuzo zokonga amandla. Libonelela ngeenzuzo zoqoqosho kunye nokusingqongileyo, libonelela ngenkxaso enamandla kuphuhliso oluluhlaza nolunekhabhoni ephantsi kwamashishini. Iziphumo zovavanyo lwasentsimini zibonisa ukuba: ubushushu obungaphakathi bumalunga ne-45–60℃, kwaye ubushushu obubonakalayo bomphezulu wezixhobo zeevalvu zokusebenza buqala kwi-110℃ ukuya kwi-190℃. Ukulahleka kobushushu kuzo zonke iimeko kudlule kakhulu ixabiso eliphezulu lokuchithwa kobushushu elivunyelweyo elichazwe kwi-GB/T 8174-2008 esemgangathweni kazwelonke.
Kwiprojekthi yokuxhobisa zonke izixhobo ezikwi-R2/R3/oil press/refinery/boiler workshop ngeejakethi zokukhusela ezinokususwa, inkampani yethu igqibezele uqikelelo lwebhajethi yeprojekthi ngokusekelwe kwiiparameter zeenkcukacha ze-matrix yezixhobo, izalathi zokusebenza ze Izinto zokuvala ubushushus (ukuqhuba ubushushu λ ≤ 0.030W/(m·℃)) kunye neemfuno zokwenza ngokwezifiso zemodyuli. Isicatshulwa esipheleleyo sale bhatshi yeejakethi zokukhusela silandelayo: [R2: USD 7160.04], [R3: USD 10856.00], [ucinezelo lweoyile: USD 37391.73], [ukucoca: USD 26006.76], [indawo yokusebenzela iibhoyila: USD 3009.55]. Esi sicatshulwa siquka ukubonelela ngezinto, ukucutshungulwa ngokwezifiso, ukulungelelaniswa kwindawo kunye nokugunyaziswa. Ngokwembono yembuyekezo yotyalo-mali lweprojekthi, kuxhomekeke kwizinga lokunciphisa ukusetyenziswa kwamandla okusasazwa kobushushu ngonyaka (≥ 85%) elifezekiswe yile nkqubo yokukhusela, ixesha lokubuyisela eliguqukayo liqikelelwa ukuba ziinyanga ezi-8, ezinokugubungela ngempumelelo utyalo-mali lokuqala kwaye zivelise iingenelo ezihlala zihleli ezivela ekuphuculeni iindleko zamandla.
