A: Ijenereyitha yomphunga ifudumeza kwaye ikhuphe amanzi akwiziko ngokutshiswa kwamafutha okubonelela ubomi kunye nokufudumeza. Ngaphantsi kweemeko eziqhelekileyo, ukujikeleza kwamanzi okuthe tye kwimo ezinzile, kodwa xa isakhiwo sokujikeleza singekho umgangatho okanye ukusebenza kungafanelekanga, ezinye iintsilelo zihlala zenzeka.
Umbhobho onomphunga:
Ngaphantsi kweemeko eziqhelekileyo zokusebenza kwejeneretha ye-steam, i-steam ayikwazi ukubakho kwi-downcomer, ngaphandle koko, amanzi kufuneka aqhubele phantsi, kwaye i-steam idinga ukudada phezulu, kwaye ezi zimbini zichasene, ezingagcini nje ukwandisa ukuchasana kokuhamba, kodwa kwakhona kunciphisa ukuhamba okujikelezayo , xa imeko inzima, ukuchasana komoya kuya kwenziwa, okuya kubangela ukuba ukujikeleza kwamanzi kuyeke, okubangela ukuba iibhubhu zodonga lwamanzi zonakaliswe ngokubanzi ngenxa yokungabikho kwamanzi. Ukuze kulungiswe le ngxaki, i-downcomer ye-jenereyitha yomphunga ayifanele ibonakaliswe kubushushu, kwaye kufuneka idityaniswe kwindawo yamanzi kwi-drum, kangangoko kunokwenzeka idityaniswe phantsi kombhobho, kwaye uqinisekise ukuba ukuphakama phakathi i-inlet ye-downcomer kunye nenqanaba eliphantsi lamanzi kwi-drum alikho phantsi Amaxesha amane ububanzi be-downcomer. Ukuze kuthintelwe umphunga ukuba ungathwalwa kumbhobho.
I-Loop ibambekile:
Ngexesha lokusetyenziswa kwejenereyitha yomphunga, kwiluphu efanayo yokujikeleza, xa ityhubhu nganye enyukayo ngokunxuseneyo ifudunyezwa ngokungalinganiyo, ukuxinana komxube wamanzi omphunga kumbhobho oshushu ngokubuthathaka kufuneka ube mkhulu kunomxube wamanzi omphunga. kwityhubhu eshushu kakhulu. Ngaphantsi kwengcamango yokuba unikezelo lwamanzi lombhobho osezantsi lulinganiselwe, izinga lokuhamba kumbhobho oshushu obuthathaka linokuthi lihle, kwaye linokuba kwimeko yokumisa. Le meko ibizwa ngokuba yi-cycle stagnation. Ngeli xesha, i-steam kwipayipi ekhulayo ayikwazi ukuqhutyelwa ngexesha. , ekhokelela kwiingozi zokugqabhuka kombhobho wokutshisa kakhulu eludongeni.
Ukwaleka kweSoda:
Xa iityhubhu zodonga ezipholileyo zamanzi zejenereyitha yomphunga zicwangciswe ngokuthe tye okanye ngokuthe tye, kwaye isantya sokuhamba komxube wamanzi omphunga kwiityhubhu aliphezulu kakhulu, kuba umphunga ukhaphukhaphu kakhulu kunamanzi, umphunga uqukuqela ngaphezu kwamanzi. iityhubhu, kwaye amanzi ahamba ngaphantsi kweetyhubhu. Le meko ibizwa ngokuba yi-Soda-water stratification, ngenxa yokungahambi kakuhle kwe-thermal conductivity yomphunga, umphezulu wombhobho ugqithiswa ngokulula kwaye wonakaliswe. Ngoko ke, ukunyuka okanye ukuphuma kombhobho womxube wamanzi we-soda awukwazi ukulungiswa ngokuthe tye, kwaye ukuthambekela akufanele kube ngaphantsi kwama-degrees angama-15.
I-Loopback:
Xa ukufudumeza kwetyhubhu nganye enyukayo ngokunxuseneyo kungalingani kakhulu, umxube wamanzi ngomphunga kwityhubhu enovelwano oluqinileyo lobushushu uya kuba namandla okunyusa anamandla, isantya sokuhamba siya kuba sikhulu kakhulu kwaye isiphumo sokufunxa siya kwenziwa, sibangele umphunga. -umxube wamanzi kwi-tube ene-exposure ebuthakathaka yokushisa ukuhamba ngendlela eyahlukileyo ukusuka kwindlela eqhelekileyo yokujikeleza, le meko ibizwa ngokuba yi-reverse circulation. Ukuba isantya sokunyuka kweebhubhu siyafana nesantya sokuhla samanzi, siya kubangela ukuba iibhubhu ziqhube kwaye zenze "ukuchasana komoya", okuya kubangela ukugqabhuka kombhobho ogqithisiweyo kwicandelo lombhobho wokumelana nomoya.
