Kunezici ezimbili eziphambili ezithinta izinga lokushisa le-Steam generator ye-Steam: munye uhlangothi lwegesi lwegesi; elinye uhlangothi umusi.
Izici ezimthonya eziphambili ohlangothini lwegesi lwe-Flue yilezi:1) ushintsho ezinhlakalweni zikaphethiloli. 2) ushintsho ngevolumu yomoya nokusatshalaliswa. 3) Izinguquko ekubumbeni umlotha endaweni efudumele. 4) Izinguquko emazingeni okushisa okushisa. 5) Lungisa umsizi ongemuhle ngaphakathi kwebanga elijwayelekile.
Izici eziphambili ezinethonya ohlangothini lweSteam yilezi:1) Izinguquko emthwalweni we-Steam Generator. 2) Izinguquko ekushiseni kwe-Steated. 3) Izinguquko ekuvuleni kwamanzi okuphakelayo.
Akungatshazwa ukuthi i-Steam Generator Steam Lokushisa kungenye yamapharamitha aphambili wokusebenza okuphephile nangokomnotho kwe-Steam generator. I-Steam Generator Steam Lishisa ithinta ngqo ukuphepha nomnotho weyunithi. Amazinga okushisa aphezulu ngokweqile angadala ukuthi indawo yokushisa ishiye ipayipi, ibangele ukucindezelwa okuthe xaxa ngepayipi elivuthayo kanye nengxenye ephezulu yengcindezi ye-turbine ye-steam, ngaleyo ndlela ifinyeze impilo yenkonzo yemishini. Ngakolunye uhlangothi, izinga lokushisa eliphansi kakhulu lizonciphisa ukusebenza kahle kwezomnotho kweyunithi, futhi ezimweni ezinzima, kungakhiwa amanzi. umthelela.
Izici ezithinta izinga lokushisa le-Steam ye-Steam Generator ikakhulukazi zifaka phakathi kwezici ezintathu ezilandelayo:
1. Izinguquko ekucindezelweni okukhulu kwe-Steam
Ithonya lengcindezi ebabazekayo eSteam ekushiseni okuma-Steate osuswayo selibonakala ngokusatshalaliswa kokukhuphuka kwezinhlanzi ezisebenzayo kanye nokushintshwa kwamandla okushisa athile okushisa. Umthamo othize wokushisa umusi ohleliwe uqiniswe kakhulu yingcindezi. Umehluko phakathi kokushisa okulinganiselwe kwe-Steate kanye lokushisa kwe-saturation unyuka ngokucindezela okuphansi, kanye nomusi osondele kakhulu weSteam the Enthalpy ashukuma.
2. Ithonya lokushisa kwamanzi okuphakelayo
Lapho okushisa kwamanzi okuphakelayo kwehliswa, njengalapho ukufudumeza okuphezulu kuhoxiswa, lapho okushisa okuthe xaxa kuhlala kungavumi ukwanda kwenani lamafutha, okuholela ekwandeni kokushisa okuphelele kwesithando kanye nokushisa ngokweqile okukhazimulayo. Amazinga okushisa aphansi endaweni yokuphuma ye-convection Supertheater izokwanda; Ngakolunye uhlangothi, ukwanda kwevolumu yegesi ye-flue kanye nokushisa kokushisa kokushisa okungumehluko we-convection Supertheater uzokwandisa izinga lokushisa le-Steak. Isamba sezinguquko ezimbili sizodala ukuthi izinga lokushisa le-Steased Steased likhuphuke kakhulu. Lokhu kwanda kunomthelela omkhulu kunokumane ukhule umthwalo we-generator we-steam ngenkathi ugcina izinga lokushisa lamanzi okuphakelayo lingashintshiwe. Ngokuphambene nalokho, lapho izinga lokushisa lamanzi okuphakelayo likhuphuka, izinga lokushisa le-Steam lizokwehla.
3. Ithonya lesikhundla sesikhungo selangabi somlilo
Njengoba isikhundla sesikhungo selangabi somlilo siqhubekela phezulu, i-runlet yokushisa imusha intuthu izokwanda. Njengoba ukushisa kudonswa yi-radiant superheater kanye ne-convection Superheater inyuka futhi izinga lokushisa le-steam, isikhundla sesikhungo selangabi sinethonya elikhulu ekushiseni kwe-steate okuhlala kahle.
Izici ezithinta izinga lokushisa elivuselelayo nokushisa kwe-superheat steam ngokufanayo. Kodwa-ke, ingcindezi yokuvuselela umusi iphansi futhi izinga lokushisa elimaphakathi liphezulu. Ngakho-ke, umthamo wayo othize wokushisa mncane kunalokho kwe-Steam ephethwe kahle. Ngakho-ke, lapho inani elifanayo le-Steam lithola ukushisa okufanayo, ukuguqulwa kwezinga lokushisa kwesikhumba okushintshiwe kukhulu kune-Steam ebabazekayo. Ngamafuphi, izinga lokushisa le-Steam ye-Steam generator liyisici esibalulekile sokusebenza, kepha ngoba kunezinto eziningi ezithinta izinga lokushisa le-Steam, inqubo yokulungiswa inzima. Lokhu kudinga ukuthi ukulungiswa kokushisa okushisa kufanele kuhlaziywe kaningi futhi kubhekwe, futhi umbono wokulungiswa kwangaphambili kufanele kusungulwe.
Lapho izinga lokushisa lishintsha, kufanele siqinise ukuqapha kanye nokulungiswa kwamazinga okushisa anukuthekile, hlaziya ubudlelwano phakathi kwezici ezithonyayo nezinguquko, bese uhlola okuhlangenwe nakho okuthile ku-Steam lokushisa lokushisa.
