A:Ijeneretha yesitimu ivamise ukushisisa futhi ikhiphe amanzi esithandweni ngokusebenzisa ukuvutha kukaphethiloli ukuze kuhlinzeke ukuphila nokushisisa. Ngaphansi kwezimo ezijwayelekile, ukujikeleza kwamanzi okuvundlile kusesimweni esizinzile, kodwa uma isakhiwo sokujikeleza singalinganisi noma ukusebenza kungalungile, ukwehluleka okuthile kuvame ukwenzeka.
Ipayipi elinomusi:
Ngaphansi kwezimo ezijwayelekile zokusebenza kwe-steam generator, umusi awukwazi ukuba khona ku-downcomer, ngaphandle kwalokho, amanzi adinga ukugeleza phansi, futhi umusi udinga ukuntanta phezulu, futhi lezi ezimbili ziphikisana nomunye nomunye, okungagcini nje ukuthuthukisa ukumelana nokugeleza, kodwa futhi kunciphisa ukugeleza kokujikeleza , lapho isimo sibucayi, ukumelana komoya kuzokwakhiwa, okuzokwenza ukuthi ukujikeleza kwamanzi kume, okubangela ukuthi amashubhu odonga lwamanzi alimale ngokuvamile ngenxa yokuntuleka kwamanzi. Ukuze kuxazululwe le nkinga, i-downcomer ye-jeneretha ye-steam akufanele ibekwe ekushiseni, futhi kufanele ixhunywe endaweni yamanzi yesigubhu, ngangokunokwenzeka ixhunywe phansi kwesigubhu, futhi iqinisekise ukuthi ukuphakama phakathi i-inlet ye-downcomer kanye nezinga eliphansi lamanzi esigubhu aliphansi Ngokuphindwe kane ububanzi be-downcomer. Ukuze uvimbele ukuthi umusi ungangeni epayipini.
Iluphu ibambekile:
Ngesikhathi kusetshenziswa ijeneretha yesitimu, ku-loop efanayo yokujikeleza, lapho ishubhu ngalinye elikhuphukayo elihambisanayo lishisiswe ngokulingana, ukuminyana kwengxube yamanzi esitimu eshubhuni elishisisa kancane kufanele kube kukhulu kunaleyo yengxubevange yamanzi-amanzi. eshubhu elishisisa kakhulu. Ngaphansi kwesisekelo sokuthi ukuhlinzekwa kwamanzi kombhobho wepayipi kulinganiselwe, izinga lokugeleza epayipini elishisayo elibuthakathaka lingase lehle, futhi lingase libe sesimweni sokuma. Lesi simo sibizwa nge-cycle stagnation. Ngalesi sikhathi, umusi epayipini elikhuphukayo awukwazi ukuthwala ngesikhathi. , okuholela ezingozini zokuqhuma kwamapayipi odongeni olushisa ngokweqile.
I-Soda layering:
Lapho amashubhu odongeni apholile amanzi ejeneretha yesitimu ehlelwa ngokuvundlile noma ngokuvundlile, futhi izinga lokugeleza kwengxube yamanzi esisi emashubhuni aliphezulu kakhulu, njengoba isitimu silula kakhulu kunamanzi, umusi ugeleza ngaphezu kwamanzi. amashubhu, futhi amanzi ageleza ngaphansi kwamashubhu. Lesi simo sibizwa ngokuthi i-Soda-water stratification, ngenxa yokungahambi kahle kwe-thermal conductivity ye-steam, phezulu kwepayipi kushisa kalula futhi konakaliswe. Ngakho-ke, isikhuphukeli noma ipayipi yokuphuma yengxube ye-soda-amanzi ayikwazi ukuhlelwa ngokuvundlile, futhi ukuthambekela akufanele kube ngaphansi kwama-degree angu-15.
I-Loopback:
Lapho ukushisisa kweshubhu ngayinye ekhuphukayo ngokuhambisana kungalingani kakhulu, ingxube yamanzi esitimu eshubhuni enokuchayeka kokushisa okuqinile izoba namandla anamandla okuphakamisa, izinga lokugeleza lizoba likhulu kakhulu futhi kuzokwakheka umphumela wokudonsa, okubangela isitimu. -ingxube yamanzi e-tube ene-heat exposure ebuthakathaka ukuze igeleze ngendlela ehlukile kunendlela evamile yokujikeleza, lesi simo sibizwa ngokuthi ukujikeleza okuphambene. Uma ijubane elikhuphukayo lama-bubbles lifana nejubane lokugeleza eliya phansi lamanzi, lizokwenza ukuthi ama-bubbles aqhubeke futhi enze "ukumelana nomoya", okuzoholela ekuqhekekeni kwepayipi elishisa kakhulu esigabeni sepayipi yokumelana nomoya.
