Ijenereyitha yomphunga werhasi ikwabizwa ngokuba yibhoyila yegesi. Ijenereyitha yegesi yomphunga yinxalenye ebalulekileyo yesixhobo samandla omphunga. Iibhoyili zesikhululo samandla, ii-injini ze-steam kunye neejenereyitha zezona njini zezikhululo zamandla ombane, ngoko ke iibhoyili zesikhululo samandla zizixhobo ezibalulekileyo zokuvelisa kunye nokusebenza kwamandla ombane. Iibhoyili zemizi-mveliso zizixhobo eziyimfuneko zokubonelela ngomphunga ofunekayo kwimveliso, ukusetyenzwa kunye nokufudumeza kumashishini ahlukeneyo. Zininzi iibhoyila zemizi-mveliso kwaye zisebenzisa amafutha amaninzi. Iibhoyila zokushisa ezingcolileyo ezisebenzisa igesi ephezulu yokushisa njengomthombo wokushisa kwinkqubo yokuvelisa idlala indima ebalulekileyo ekugcinweni kwamandla.
Xa kusetyenziswa umphunga omninzi, kukho iimfuno zobushushu bomphunga. Umphunga wobushushu obuphezulu udlala indima ebalulekileyo kwiinkqubo ezifana nokufudumeza, ukubilisa, kunye nokuvala inzala. Ubushushu beejenereyitha zomphunga weNobeth bunokufikelela ngokubanzi kwi-171°C, kodwa ngamanye amaxesha abathengi baxela ukuba ubushushu bomphunga buphantsi kwaye abanako ukuhlangabezana neemfuno. Ngoko ke, siyintoni isizathu solu hlobo lwemeko? Sifanele sisisombulule njani? Masiyixubushe nawe.
Okokuqala, kufuneka sifumane isizathu sokuba ubushushu bomphunga wejenereyitha yomphunga werhasi bungekho phezulu. Ngaba kungenxa yokuba i-generator ye-steam ayinamandla ngokwaneleyo, izixhobo ziphosakele, ukulungiswa koxinzelelo akunangqiqo, okanye ubushushu be-steam obufunwa ngumsebenzisi buphezulu kakhulu, kwaye i-generator eyodwa ye-steam ayikwazi ukwanelisa.
Ezi zisombululo zilandelayo zahlukeneyo zinokwamkelwa kwiimeko ezahlukeneyo:
1. Amandla anganeleyo ejenereyitha ye-steam ngqo akhokelela ekungaphumeleli kwemveliso ye-steam ukuhlangabezana neemfuno zokuvelisa. Ubungakanani bomphunga ophuma kwijenereyitha yomphunga awukwazi ukuhlangabezana nomthamo womphunga ofunekayo kwimveliso, kwaye ubushushu ngokwemvelo abanelanga.
2. Kukho izizathu ezibini zokungaphumeleli kwezixhobo ezibangela ukuba ukushisa komphunga ophuma kwijenereyitha yomphunga ube phantsi. Enye kukuba i-gauge yoxinzelelo okanye i-thermometer iyasilela kwaye ubushushu bexesha langempela lomphunga kunye noxinzelelo alukwazi ukubeka iliso ngokuchanekileyo; enye kukuba ityhubhu yokufudumeza itshiswa ngaphandle, ubungakanani bomphunga owenziwe yijenereyitha ye-steam buba buncinci, kwaye ubushushu abukwazi ukuhlangabezana neemfuno zokuvelisa.
3. Ngokuqhelekileyo, ubushushu kunye noxinzelelo lwe-steam egcweleyo luhambelana ngokuthe ngqo. Xa uxinzelelo lomphunga lunyukile, ubushushu buya kunyuka. Ke ngoko, xa ufumanisa ukuba ubushushu bomphunga ophuma kwijenereyitha yomphunga awuphezulu, unokuhlengahlengisa igeyiji yoxinzelelo ngokufanelekileyo.
Ubushushu bomphunga abukho phezulu kuba xa uxinzelelo lungekho ngaphezulu kwe-1 MPa, linokufikelela kuxinzelelo oluncinci lwe-0.8 MPa. Isakhiwo sangaphakathi sejeneretha ye-steam sikwimeko yoxinzelelo olubi (ngokusisiseko luphantsi kunoxinzelelo lwe-atmospheric, ngokuqhelekileyo lungaphezu kwe-0). Ukuba uxinzelelo lunyuswe kancinci nge-0.1 MPa, kufuneka kubekho ukulungiswa koxinzelelo. Ngamanye amazwi, nokuba ingaphantsi kwe-0, sebenzisa Ikwayijenereyitha yomphunga ngaphakathi kwe-30L, kwaye ubushushu buya kuba ngaphezulu kwe-100 ° C.
Uxinzelelo luphezulu kune-0. Nangona andiyazi ukuba yintoni ubungakanani, ukuba bukhulu kunoxinzelelo lwe-atmospheric, kuya kuba phezulu kune-100 degrees. Ukuba uxinzelelo luphezulu kunoxinzelelo lwe-atmospheric, ukushisa kweoli yokuhambisa ukushisa kuphantsi kakhulu, okanye i-coil evaporator iyatshiswa kwaye ihlanjwe. Ngokuqhelekileyo, yipropathi ebonakalayo yomphunga wamanzi. Iza kuba ngumphunga xa ifikelela kwi-100, kwaye umphunga awukwazi ukufikelela lula kumaqondo obushushu aphezulu.
Xa umphunga ufumana uxinzelelo, umphunga uya kubona iqondo lobushushu eliphezulu kancinane, kodwa ukuba wehla ngaphantsi koxinzelelo oluqhelekileyo lwe-atmospheric, iqondo lobushushu liyakwehla ngoko nangoko liye kutsho kwi-100. Ekuphela kwendlela yokwenza into enje ngaphandle kokunyusa uxinzelelo lwe-injini yomphunga kukujika. umphunga ube nguxinzelelo olubi. Ngalo lonke ixesha uxinzelelo lwe-steam lukhula malunga ne-1, ukushisa kwe-steam kuya kwanda malunga ne-10, njalo njalo, ubungakanani beqondo lokushisa elifunekayo kunye nokuba uxinzelelo lufuna ukwanda kangakanani.
Ukongeza, ingaba iqondo lokushisa lomphunga liphezulu okanye alijoli. Ukuba ezi ndlela zingasentla azikwazi ukucombulula ingxaki yobushushu obuphantsi bomphunga obuphuma kwijenereyitha yomphunga, kusenokuba kuphela ukuba ubushushu obufunekayo buphezulu kakhulu kwaye bugqithise umthamo wesixhobo. Kule meko, ukuba akukho mfuneko zingqongqo kuxinzelelo, cinga ukongeza iheater yomphunga.
Isishwankathelo, ezi ngasentla zonke izizathu zokuba kutheni ukushisa komphunga wejeneretha ye-steam ayiphezulu. Kuphela ngokuphelisa iingxaki ezinokwenzeka nganye nganye sinokufumana indlela yokwandisa ubushushu bomphunga ophuma kwijenereyitha yomphunga.
