Q: Ungakuhlukanisa kanjani phakathi kukamusi ogcwele kanye nomusi ophakeme?

A:

Kalula nje, i-Steam Generator iyi-boiler yezimboni eshisa amanzi ngezinga elithile ukukhiqiza umusi wokushisa aphezulu. Abasebenzisi bangasebenzisa umusi wokukhiqizwa kwezimboni noma ukufudumeza njengoba kudingeka.

Ama-generator we-Steam abiza kakhulu futhi kulula ukuyisebenzisa. Ikakhulu, ama-generator wegesi we-Steam kanye nama-generator kagesi kagesi asebenzisa amandla ahlanzekile ahlanzekile nokungcoliswa.

Lapho uketshezi luphuma esikhaleni esilinganiselwe, ama-molecule awuketshezi angena esikhaleni esingenhla ngokusebenzisa indawo yoketshezi futhi abe ama-molecule we-vapor. Njengoba ama-molecule e-steam ahamba ngesiphithiphithi esishisayo, ahlangana nomunye, udonga lwesitsha kanye nomphezulu woketshezi. Lapho ushayisana nogesi, amanye ama-molecule akhangwa ama-molecule awuketshezi bese ubuyela ku-liquid ukuze ube ama-molecule awuketshezi. . Lapho i-EviPorm ingaqala, inani lama-molekyuli angena esikhaleni likhulu kunenani lama-molecule abuyela ku-ketshezi. Njengoba ukuhwamuka kuqhubeka, ubuningi bama-molecule we-vapor esikhaleni kuyaqhubeka ukwanda, ngakho-ke inani lama-molecule abuyela ku-liquid futhi liyanda. Lapho inani lama-molekyuli lingena esikhaleni ngasinye isikhathi seyunithi lilingana nenani lama-molecule abuyela ku-ketshezi, ukuhwamuka kanye nokuvuselelwa kusesimweni sokulingana okunamandla. Ngalesi sikhathi, yize ukuhwamuka nokuvuselelwa kusaqhubeka, ubuningi bama-molecule we-vapor esikhaleni ayisakhuphuke. Isimo ngalesi sikhathi sibizwa ngokuthi uMgqibelo. Uketshezi esimweni esigcwele ubizwa ngokuthi uketshezi olugcwele, futhi umphunga wawo ubizwa ngokuthi umusi ogcwele owomile (obizwa nangokuthi umusi ogcwele).

Uma umsebenzisi efuna ukufezekisa amamitha anembe kakhudlwana nokuqapha, kunconywa ukukuphatha njengomusi osheshe futhi anxephezele izinga lokushisa nengcindezi. Kodwa-ke, ukucabanga ngezinkinga zezindleko, amakhasimende angabuye anxephezele amazinga okushisa kuphela. Isimo seSteam esikahle esiphelele sibhekisele ebudlelwaneni obuhambisana nobunye phakathi kokushisa, ingcindezi kanye nobuningi beSteam. Uma omunye wabo waziwa, amanye amanani amabili ahleliwe. Umusi onalobu budlelwano ugcwele umusi, ngaphandle kwalokho kungabhekwa njengomusi ophakeme wokulinganisa. Ekusebenzeni, izinga lokushisa likaSteam Superheated lingaba liphezulu, futhi ingcindezi ngokuvamile iphansi kakhulu (i-Steath Steath), 0.7MPA, u-200 ° C Steam unje, futhi umusi omkhulu.

Njengoba i-Steam Generator iyithuluzi lamandla ashisekayo elisetshenziselwa ukuthola umusi osezingeni eliphakeme, linikeza umusi okhiqizwe izinqubo ezimbili, okungukuthi umusi ogcwele uSteam noSteate onamandla. Omunye angabuza, Uyini umehluko phakathi kukaSteam ogcwele kanye noSteate ophakeme ku-generator emutha? Namuhla, noBobth uzokhuluma nawe ngomehluko phakathi kukamusi ogcwele uSteate noSteate.

1. I-Steath Steated noSteate Superheated banobudlelwano obuhlukile ngokushisa kanye nengcindezi.
Umusi ogcwele uSteate utholwe ngokuqondile emanzini okushisa. Izinga lokushisa, ingcindezi, nobuningi bomusi ogcwele uhambelana noyedwa. Amazinga okushisa aphansi ngaphansi kwengcindezi efanayo yezulu ngu-100 ° C. Uma izinga lokushisa eliphakeme liyadingeka, vele ukhuphule ingcindezi ye-steam.
USteated Steate wavuselelwa ngesisekelo somusi ogcwele, okungukuthi, umusi okhiqizwe ngokushisa kwesibili.Umphunga we-Steather we-Vapor uhlala ungashintshiwe, kepha izinga lokushisa laso liyanda.

USteate Ophakeme uvame ukusetshenziswa ezitshalweni zamandla afudumele ukushayela i-steam turbines ukukhiqiza ugesi.
Umuphu ogcwele uvame ukusetshenziswa ngokushisa kwemishini noma ukushintshaniswa kokushisa.

I-3. Ukusebenza kokushintshanisa kokushisa komusi ogcwele uSteam noSteate Superheated kwehlukile.
Ukusebenza kahle kokushisa kukaSteate Superheated kuphansi kunaleso somusi ogcwele.
Ngakho-ke, ngesikhathi senqubo yokukhiqiza, umusi ophakeme kakhulu udinga ukuguqulwa ube umusi ogcwele ukuncishiswa kwezinga lokushisa kanye nengcindezi yokunciphisa ukunciphisa.
Isikhundla sokufaka se-Dupsurthether nengcindezi ukunciphisa isiphetho sangaphambili semishini yokusebenzisa kamusi kanye nokuphela kwesilinda. Kunganikeza umusi ogcwele ukugcwala kwemishini eyodwa noma eminingi esebenzisa ama-Steam-usebenzisa ukukhiqiza.
