A:Ukulawula okulungile kokucindezela kwesitimu kuvame ukubalulekile ekwakhiweni kwesistimu yesitimu ngoba ukucindezela kwesitimu kuthinta ikhwalithi yesitimu, izinga lokushisa lomusi, namandla okudlulisa ukushisa kwesitimu. Umfutho we-steam uphinda uthinte ukukhishwa kwe-condensate kanye nokukhiqizwa kwesitimu sesibili.
Kwabahlinzeki bemishini ye-boiler, ukuze kuncishiswe umthamo wama-boilers futhi kuncishiswe izindleko zemishini ye-boiler, ama-boilers we-steam ngokuvamile aklanyelwe ukusebenza ngaphansi kwengcindezi ephezulu.
Lapho i-boiler isebenza, ingcindezi yangempela yokusebenza ngokuvamile iphansi kunokucindezela kokusebenza kokuklama. Nakuba ukusebenza kuwumsebenzi wengcindezi ephansi, ukusebenza kahle kwe-boiler kuzokwenyuka ngendlela efanele. Kodwa-ke, lapho usebenza ngomfutho ophansi, okukhiphayo kuzoncishiswa, futhi kuzokwenza ukuthi umusi "uthwale amanzi". I-vapor carryover iyingxenye ebalulekile yokusebenza kahle kokuhlunga kwesitimu, futhi lokhu kulahlekelwa kuvame ukuba nzima ukukubona nokukala.
Ngakho-ke, ama-boilers ngokuvamile akhiqiza umusi ngokucindezela okukhulu, okungukuthi, asebenze ngokucindezela eduze nokucindezela kokuklama kwe-boiler. Ukuminyana kwesitimu esinomfutho ophezulu kuphezulu, futhi amandla okugcina igesi endaweni yawo yokugcina isitimu nawo azokhula.
Ukuminyana kwesitimu esinomfutho ophakeme kuphezulu, futhi inani lesitimu somfutho ophezulu odlula epayipini lobubanzi obufanayo likhulu kunelo lomusi onengcindezi ephansi. Ngakho-ke, amasistimu amaningi okulethwa kwesitimu asebenzisa isitimu esinomfutho ophezulu ukuze sinciphise usayizi wamapayipi okulethwa.
Yehlisa ingcindezi ye-condensate endaweni yokusetshenziswa ukonga amandla. Ukunciphisa ingcindezi kwehlisa izinga lokushisa kumapayipi angezansi komfula, kunciphisa ukulahleka okunganyakazi, futhi kunciphisa ukulahleka kwesitimu esikhanyayo njengoba siphuma ogibeni siya ethangini lokuqoqa i-condensate.
Kuyaphawuleka ukuthi ukulahlekelwa kwamandla ngenxa yokungcola kuyancipha uma i-condensate ikhishwa ngokuqhubekayo futhi uma i-condensate ikhishwa ngokucindezela okuphansi.
Njengoba ukucindezela komhwamuko nokushisa kuhlobene, kwezinye izinqubo zokushisa, izinga lokushisa lingalawulwa ngokulawula ukucindezela.
Lolu hlelo lokusebenza lungabonakala kuma-sterilizers nama-autoclave, futhi isimiso esifanayo sisetshenziselwa ukulawula izinga lokushisa elingaphezulu kuma-dryer othintana nawo wezicelo zephepha nebhodi likathayela. Kuma-dryer ahlukahlukene othintana naye, ingcindezi yokusebenza ihlobene eduze nesivinini sokujikeleza kanye nokuphuma kokushisa kwesomisi.
Ukulawula ingcindezi kuyisisekelo sokulawula izinga lokushisa lokushintshanisa ukushisa.
Ngaphansi komthwalo ofanayo wokushisa, ivolumu yesishintshi sokushisa esisebenza ngesitimu sokucindezela okuphansi sikhulu kunaleyo yesishintshi sokushisa esisebenza ngesitimu sokucindezela okuphezulu. Izishintshi zokushisa ezinengcindezi ephansi zinezindleko eziphansi kunezishintshisi zokushisa ezinengcindezi ephezulu ngenxa yezidingo zazo eziphansi zokuklama.
Isakhiwo seshabhu sinquma ukuthi ucezu ngalunye lwesisetshenziswa lunengcindezi yokusebenza ephezulu evumelekile (MAWP). Uma lokhu kucindezela kungaphansi kokucindezela okukhulu okungaba khona kwesitimu esihlinzekiwe, isitimu kufanele sicindezeleke ukuze kuqinisekiswe ukuthi ukucindezela ohlelweni olungezansi komfula aweqi ukucindezela okukhulu okuphephile kokusebenza.
Amadivayisi amaningi adinga ukusetshenziswa kwe-steam ngezingcindezi ezahlukene. Isistimu ethile ikhanyisa amanzi ajikijelwe ngomfutho ophezulu abe isitimu esinomfutho ophansi ukuze sinikeze ezinye izinhlelo zokusebenza zenqubo yokushisisa ukuze kufezwe izinjongo zokonga amandla.
Uma inani le-flash steam elakhiwe linganele, kuyadingeka ukugcina ukunikezwa kwesitimu esizinzile nokuqhubekayo. Ngalesi sikhathi, i-valve yokunciphisa ingcindezi iyadingeka ukuze kuhlangatshezwane nesidingo.
Ukulawulwa komfutho we-steam kubonakala kuzixhumanisi ze-lever zokukhiqiza umusi, ezokuthutha, ukusatshalaliswa, ukushintshaniswa kokushisa, amanzi ajiyile kanye nesitimu esikhanyayo. Indlela yokufanisa ukucindezela, ukushisa nokugeleza kwesistimu ye-steam kuyisihluthulelo sokwakhiwa kwesistimu ye-steam.
