Silawulwa njani isantya sokuqalisa kwibhoyila? Kutheni isantya sokunyusa uxinzelelo singenakukhawuleza kakhulu?
Uxinzelelo lokunyusa isantya kwinqanaba lokuqala lokuqalisa kwebhoyila kwaye ngexesha layo yonke inkqubo yokuqalisa kufuneka icothe, ngokulinganayo, kwaye ilawulwe ngokungqongqo kuluhlu oluchaziweyo. Kwinkqubo yokuqalisa i-high-pressure kunye ne-ultra-high-high-high-pressure steam drum boilers, ukunyuka kwesantya soxinzelelo kulawulwa ngokubanzi ukuba kube yi-0.02 ~ 0.03 MPa / min; kwiiyunithi zasekhaya ezingama-300MW, isantya sokwanda koxinzelelo akufuneki sibe sikhulu kuno-0.07MPa/min phambi koqhagamshelo lwegridi, kwaye akufanele ukuba lukhulu kuno-0.07 MPa/min emva koqhagamshelo lwegridi. 0.13MPa/min.
Kwinqanaba lokuqala lokunyusa, ngenxa yokuba kufakwe izitshisi ezimbalwa kuphela, ukutsha kubuthathaka, idangatye lomlilo aligcwaliswanga kakuhle, kwaye ukufudumeza kwendawo yokufudumeza i-evaporation ayilingani; kwelinye icala, ngenxa yokuba ubushushu bomgangatho wokufudumeza kunye nodonga lwesithando somlilo luphantsi kakhulu, Ngoko ke, phakathi kobushushu obukhutshwe ngokutshiswa kwamafutha, akukho bushushu obuninzi obusetyenziselwa ukufunxa amanzi eziko. Okukhona usezantsi uxinzelelo, kokukhona ubushushu obufihliweyo bomphunga, ngoko akukho mphunga omninzi uveliswayo kumphezulu womphunga. Umjikelo wamanzi awumiselwanga ngokuqhelekileyo, kwaye ukufudumala akukwazi ukukhuthazwa ngaphakathi. Umphezulu ushushu ngokulinganayo. Ngale ndlela, kulula ukubangela uxinzelelo olukhulu lwe-thermal kwisixhobo sokuphefumula, ngakumbi idrum yomphunga. Ngoko ke, izinga lokunyuka kweqondo lokushisa kufuneka lihambe ngokukhawuleza ekuqaleni kokunyuka koxinzelelo.
Ukongeza, ngokotshintsho phakathi kobushushu bokuhlala kunye noxinzelelo lwamanzi kunye nomphunga, kunokubonwa ukuba ukuphakama koxinzelelo, lincinci ixabiso lobushushu bokuhlala litshintsha ngoxinzelelo; Xa uphantsi koxinzelelo, ixabiso elikhulu lobushushu bokuhlala litshintsha ngoxinzelelo, oko kubangela umahluko weqondo lobushushu Uxinzelelo olugqithisileyo lobushushu luyakwenzeka. Ke ukunqanda le meko, ixesha lokunyuswa kufuneka libe lide.
Kwinqanaba lamva lokunyuka koxinzelelo, nangona umahluko weqondo lokushisa phakathi kweendonga ezingaphezulu nezisezantsi zegubu kunye neendonga zangaphakathi nangaphandle zincitshiswe kakhulu, isantya sokunyusa uxinzelelo sinokukhawuleza kunokuba kwinqanaba eliphantsi loxinzelelo, kodwa i-mechanical uxinzelelo olubangelwa ukunyuka koxinzelelo lokusebenza lukhulu, ngoko ke uxinzelelo kwinqanaba lokugqibela Isantya sokunyusa akufanele sidlule isantya esichazwe kwimimiselo.
Inokubonwa koku ngasentla ukuba ngexesha lenkqubo yokunyusa uxinzelelo lwebhoyila, ukuba isantya sokunyusa uxinzelelo sikhawuleza kakhulu, siya kuchaphazela ukhuseleko lwegubu lomphunga kunye nezinto ezahlukeneyo, ngoko ke isantya sokunyusa uxinzelelo asikwazi ukukhawuleza.
Yiyiphi imiba ekufuneka ihlawulwe ingqalelo xa iyunithi iqala ukutshisa kunye noxinzelelo?
(1) Emva kokuba ibhoyila ilayitiwe, ukuvuthelwa komsizi kwisifudumezi sokuqala kufanele komelezwa.
(2) Lawula ngokungqongqo ukunyuka kweqondo lobushushu kunye nesantya sokunyuka koxinzelelo ngokweyunithi yegophe lokuqalisa, kwaye ubeke iliso umahluko wobushushu phakathi kwamagubu aphezulu nasezantsi kunye neendonga zangaphakathi nangaphandle zingadluli kuma-40°C.
(3) Ukuba isifudumezisi siphelelwe ngumlilo, iqondo lobushushu lomsi eliphuma kwiziko kufuneka lilawulwe ngokungqongqo lingagqithi ubushushu obuvumelekileyo bodonga lwetyhubhu, kwaye isifudumezi kunye neendonga zetyhubhu kufuneka zibekwe iliso elibukhali ukuze kuthintelwe ukufudumeza okugqithisileyo.
(4) Jonga ngokusondeleyo umgangatho wamanzi egubu kwaye uvule isivalo sokujikeleza kwakhona kwe-economizer xa unikezelo lwamanzi luyekile.
(5) Lawula ngokungqongqo umgangatho weziselo zesoda.
(6) Vala ucango lomoya kunye nevalve yokukhupha umphunga ngexesha.
(7) Ukubeka iliso rhoqo kwigalelo lomlilo wesithando somlilo kunye ne-oil gun, ukuqinisa ukugcinwa kunye nokulungiswa kwe-oil gun, kunye nokugcina i-atomization efanelekileyo kunye nokutsha.
(8) Emva kokuba i-injini yomphunga ibhukuqiwe, gcina iqondo lobushushu lomphunga likwinqanaba lobushushu obungaphezu kwama-50°C. Umahluko weqondo lobushushu phakathi kwamacala amabini omphunga oshushu kakhulu kunye nomphunga ophinde wafudunyezwa akufanele ube ngaphezu kwama-20°C. Sebenzisa amanzi atshisayo ngononophelo ukuthintela ukuguquguquka okukhulu kubushushu bomphunga.
(9) Jonga rhoqo kwaye urekhode imiyalelo yokwandiswa kwenxalenye nganye ukuthintela umqobo.
(10) Xa ukungaqhelekanga kufunyenwe kwisixhobo esichaphazela ngokuthe ngqo ukusebenza okuqhelekileyo, ixabiso kufuneka lixelwe, ukunyuka kwengcinezelo kufuneka kumiswe, kwaye ukunyuka koxinzelelo kufuneka kuqhutyelwe emva kokuba iziphene zipheliswe.
