Kukho izinto ezimbini eziphambili ezichaphazela ukushisa komphunga we-steam generator: enye yicala legesi ye-flue; elinye icala lomphunga.
Imiba ephambili enempembelelo kwicala lerhasi yeflue zezi:1) Utshintsho kwiimpawu zamafutha. 2) Utshintsho kumthamo womoya kunye nokusabalalisa. 3) Utshintsho ekubunjweni komlotha kwindawo yokufudumala. 4) Utshintsho kwiqondo lokushisa lesithando somlilo. I-5) Lungisa uxinzelelo olubi lwesithando somlilo ngaphakathi koluhlu oluqhelekileyo.
Izinto eziphambili ezinempembelelo kwicala lomphunga zezi:1) Utshintsho kumthwalo wejeneretha yomphunga. 2) Utshintsho kwiqondo lokushisa lomphunga. 3) Utshintsho kubushushu bamanzi esondlo.
Akungabazeki ukuba ukushisa kwe-steam generator ngumphunga yenye yeeparameters eziphambili zokusebenza ngokukhuselekileyo kunye noqoqosho lwejenereyitha ye-steam. Ubushushu be-steam generator steam buchaphazela ngokuthe ngqo ukhuseleko kunye noqoqosho lweyunithi. Ukushisa okugqithisileyo komphunga kunokubangela ukuba umphezulu wokufudumeza ugqithise kwaye ugqabhuke umbhobho, kubangele uxinzelelo olongezelelweyo lwe-thermal kumbhobho we-steam kunye nenxalenye yoxinzelelo oluphezulu lwe-injini ye-steam, ngaloo ndlela inciphisa ubomi benkonzo yesixhobo. Ngakolunye uhlangothi, iqondo lokushisa eliphantsi kakhulu liya kunciphisa ukusebenza kakuhle kwezoqoqosho kwiyunithi, kwaye kwiimeko ezinzima, amanzi anokuveliswa. impembelelo.
Izinto ezichaphazela ubushushu bomphunga wejenereyitha yomphunga ikakhulu ziquka le miba mithathu ilandelayo:
1. Utshintsho kuxinzelelo oluphambili lomphunga
Impembelelo yoxinzelelo oluphambili lomphunga kwiqondo lobushushu bomphunga ogqithisiweyo luqondwa ngokusasazwa kokunyuka okuphakathi kwe-enthalpy kunye nokutshintsha umthamo wobushushu obuthile. Umthamo othile wokushisa we-steam eshushu kakhulu uchaphazeleka kakhulu luxinzelelo. Umahluko phakathi kweqondo lokushisa elilinganisiweyo kunye nokushisa kwe-saturation kwanda kuxinzelelo oluphantsi, kunye ne-superheated steam epheleleyo Ukunyuka kwe-enthalpy kuya kuncipha.
2. Impembelelo yobushushu bamanzi esondlo
Xa ubushushu bamanzi okutya buthotywa, njengaxa ukufudumeza okuphezulu kurhoxiswa, xa imveliso yejenereyitha yomphunga ihlala ingaguquki, ubushushu obuphantsi bamanzi bokutya bukhokelela ekwandeni komthamo wepetroli, okukhokelela ekunyukeni kobushushu obupheleleyo. kwisithando somlilo kunye nokwahlukana kweqondo lokushisa phakathi komsi wokuphuma kwesithando somlilo kunye nokushisa okukhazimulayo. Ubushushu bomphunga kwindawo yokuphuma ye-convection superheater iya kwanda; kwelinye icala, ukonyuka komthamo wegesi yombane kunye nokutshintsha kobushushu bokutshintsha kobushushu be-convection superheater kuya kwandisa ubushushu bomphunga wokuphuma. Isimbuku sezi nguqu zimbini siya kubangela ukuba ubushushu bomphunga obushushu bonyuke kakhulu. Olu lwando lunempembelelo enkulu kunokunyusa nje umthwalo wejenereyitha yomphunga ngelixa ugcina ubushushu bamanzi esondlo bungatshintshi. Ngokuchasene noko, xa iqondo lokushisa lamanzi esondlo linyuka, ukushisa kwe-steam kuya kuncipha.
3. Impembelelo yendawo ephakathi yomlilo wesithando somlilo
Njengoko indawo esembindini yomlilo wesithando somlilo ihambela phezulu, iqondo lobushushu lomsi lomlilo liya kwanda. Ukusukela oko ubushushu obufunxwa sisifudumezi esikhazimlayo kunye ne-convection superheater inyuka kunye nobushushu bomphunga bunyuka, indawo eseziko ledangatye inefuthe elikhulu kubushushu obushushu kakhulu.
Izinto ezichaphazela ubushushu bokufudumala komphunga kunye nobushushu obuphezulu bobushushu buyafana. Nangona kunjalo, uxinzelelo lomphunga olushushu luphantsi kwaye ubushushu obuphakathi buphezulu. Ke ngoko, amandla ayo obushushu obuthile buncinci kunomoya oshushu kakhulu. Ngoko ke, xa umlinganiselo ofanayo womphunga ufumana ubushushu obufanayo, utshintsho lobushushu bomphunga ofudunyeziweyo mkhulu kunolo lobushushu obugqithiseleyo. Ngamafutshane, ukushisa kwe-steam ye-steam generator yinto ebalulekileyo yokusebenza, kodwa ngenxa yokuba kukho izinto ezininzi ezichaphazela ukushisa komphunga, inkqubo yokulungelelanisa inzima. Oku kufuna ukuba ukulungiswa kobushushu bomphunga kufuneka kuhlalutywe kwaye kuqwalaselwe rhoqo, kwaye nombono wohlengahlengiso lwangaphambili kufuneka usekwe.
Xa iqondo lokushisa litshintsha, kufuneka someleze ukubeka iliso kunye nokulungelelaniswa kobushushu bomphunga, sihlalutye ubudlelwane phakathi kwezinto ezichaphazelayo kunye notshintsho, kwaye sihlolisise amava athile kuhlengahlengiso lobushushu bomphunga ukukhokela imisebenzi yethu yohlengahlengiso.
