Inkqubo yangaphambili yobugcisa yokubuyisela ubushushu benkunkuma ye-steam ayichanekanga kwaye ayifezekanga. Ubushushu benkunkuma kwijenereyitha yomphunga buxhomekeke kwinkqubo yokuvuthela kwejenereyitha yomphunga. Indlela yokubuyisela eqhelekileyo ngokuqhelekileyo isebenzisa i-blowdown expander ukuqokelela amanzi e-blowdown, kwaye emva koko yandisa umthamo kwaye icinezele ukuba ifake ngokukhawuleza i-steam yesibini, kwaye isebenzise amanzi amdaka aveliswa ngumphunga wesibini Ubushushu benza umsebenzi omhle wokufudumeza amanzi.
Kwaye kukho iingxaki ezintathu kule ndlela yokurisayikilisha. Okokuqala, amanzi amdaka akhutshwa kwijenereyitha yomphunga asenamandla amaninzi, angenakusetyenziswa ngokufanelekileyo; okwesibini, ubushushu bokutsha bejenereyitha yomphunga werhasi bumbi, kwaye uxinzelelo lokuqalisa luhlwempuzekile. Ukuba iqondo lokushisa lamanzi adibeneyo liphezulu kancinci, ipompo yokuhambisa amanzi iya kwenziwa. Umphunga, awukwazi ukusebenza ngokuqhelekileyo; Okwesithathu, ukuze kugcinwe imveliso ezinzileyo, umthamo omkhulu wamanzi ompompo kunye namafutha kufuneka utyalwe.
Ezi ndlela zimbini zilandelayo zidla ngokusetyenziswa ukujongana nokurisayikilishwa kweejenereyitha zomphunga eziqhelekileyo.
Enye kukuqwalasela kwinkalo ye-preheater yomoya. I-preheater yomoya kunye nombhobho wokushisa njengenxalenye engundoqo yokutshintshwa kobushushu ikhethiweyo, kunye nokusebenza kakuhle kokutshintshiselana kobushushu kunokufikelela ngaphezu kwe-98%, engaphezulu kuneyokutshintshisa ubushushu obuqhelekileyo. Esi sixhobo se-preheater somoya sikhaphukhaphu kuyilo kwaye sithatha indawo encinci, isinye kwisithathu kuphela somtshintshi wobushushu oqhelekileyo. Ukongezelela, inokuphepha ngokufanelekileyo ukubola kwe-asidi ye-fluid kwi-heat exchanger kunye nokwandisa ubomi benkonzo ye-heat exchanger.
Okwesibini kukuqala ngokuxuba amanzi adibeneyo kunye nezixhobo zonyango. Ukutywinwa kunye noxinzelelo oluphezulu lobushushu obuxubeneyo bokubuyiswa kwamanzi kunye nezixhobo zokunyanga zinokufudumeza ngokuthe ngqo indawo yobushushu obuphezulu kunye nobushushu obuphezulu bamanzi adityanisiweyo, khetha ubushushu obuphezulu bobushushu obuxubeneyo bokubuyisela amanzi kwaye ubuyisele ngokuthe ngqo kwaye uyicinezele kwijenereyitha yomphunga-Inkqubo evaliweyo yelophu yokuhlaziya umphunga iphucula isantya sokusetyenziswa kobushushu bomphunga. Kwakhona kunciphisa ilahleko yamandla ombane kunye namandla etyuwa, kunciphisa umthwalo wejenereyitha yomphunga, kwaye kunciphisa isixa esikhulu samanzi athambileyo.
Umxholo ongentla apha ubukhulu becala yinkcazo emfutshane malunga nemiba yobugcisa yokubuyisela ubushushu benkunkuma evela kwijeneretha ze-steam, kwaye kusafuneka ukuba ucinge ngononophelo malunga nemiba ethile.
