Q: Ungahlukanisa njani phakathi kweSteam egxunyelweyo kunye neSteam eguqukayo?

A:

Ngamafutshane, umvelisi we-Steam yi-Boiler yemveliso etshixa amanzi kangangendawo ethile yokuvelisa isitya seqondo eliphezulu. Abasebenzisi banokusebenzisa i-Steam kwimveliso yeshishini okanye ukufudumeza njengoko kufuneka.

I-Steam Generators ziindleko eziphantsi kwaye kulula ukuzisebenzisa. Ngokukodwa, abavelisi berhasi yerhasi kunye nabavelisi bombane abasebenzisa amandla abasebenzisa amandla acocekileyo bacocekile kwaye bangenalo ngongcoliseko.

Xa ulwelo luphuma kwindawo evaliweyo elivaliweyo, iimolekyuli ezingamanzi zingena kwindawo engaphezulu komgangatho wamanzi kwaye ibe ziimolekyuli ze-vapor. Kuba iimolekyuli ze-steam zikwisithukuthezi se-chaotal, ziyangqubana, eludongeni lwesitya kunye nomphezulu onamanzi. Xa ungqubana nomphezulu onamanzi, ezinye iimolekyuli zitsaleleka ziimolekyuli ezingamanzi kwaye zibuyele kulwelo ukuze zibe ziimolekyuli ezingamanzi. . Xa iqala ekutyeni, inani leemolekyuli ezingena kwisithuba likhulu kunenani leemolekyuli ezibuyela kulwelo. Njengoko i-elvatoration iyaqhubeka, ukuxinana kweemolekyuli ze-vapor kwithuba kuyaqhubeka nokunyuka, ukuze inani leemolekyuli zibuyela kulwelo nazo ziyanda. Xa inani leemolekyuli ezingena kwisithuba kwixesha ngalinye lilingana nenani leemolekyuli ezibuyela kulwelo, ukuphuma kunye nokunikezela kwi-prolifibribribribraum yokulingana. Ngeli xesha, nangona ukuphelisa ukuphuma kunye nokuzithemba kusenokuqhubeka, ukuxinana kweemolekyuli ze-vapor kwisithuba esingasanyukanga. Imeko ngeli xesha ibizwa ngokuba nguMbuso weSizwe. Ulwelo kwiLizwe eligcweleyo lubizwa ngokuba lulwelo olugcweleyo, kwaye umphunga wayo ubizwa ngokuba yi-Steam eyomileyo (ekwabizwa ngokuba yiSteam Steam).

Ukuba umsebenzisi ufuna ukufezekisa ukupeyinta ngokuchanekileyo, kuyacetyiswa ukuba ikwazi ukuthathe i-Steam eguqukayo kwaye ihlawule ubushushu kunye noxinzelelo. Nangona kunjalo, ukuqwalasela imiba yeendleko, abathengi banokuhlawula iqondo lobushushu kuphela. I-Steam Steam Steam egxunyeneyo ibhekisa kubudlelwane obuhambelanayo phakathi kobushushu, uxinzelelo kunye nokuxinana kwe-steam. Ukuba omnye wabo uyaziwa, ezinye izinto ezimbini zilungisiwe. I-Steam nolu lwalamano lugcwele isitya, kungenjalo sithathwa njengamagqabantshintshi aqingqiweyo kumlinganiso. Ukuziqhelanisa, iqondo lobushushu le-Steam elihlanganisiweyo linokuphakama, kwaye uxinzelelo lusezantsi kakhulu (i-0.7MPA egcweleyo), i-0.7MPA, 200 ° C Steam inje, kwaye inamandla steam.

Kuba isixhobo seSteam sisixhobo samandla se-thermal esisetyenziselwa ukufumana i-Steam esemgangathweni, ibonelela nge-steam eveliswe ziinkqubo ezimbini, ezizezisi Omnye umntu unokubuza, yintoni umahluko phakathi kwe-Steam egxunyelweyo kunye ne-Steam eqinileyo kwi-Steam Generator? Namhlanje, uNobith uza kuthetha nawe malunga nohluko phakathi kwe-Steam egcwelekileyo kunye ne-Steam eguqukayo.

I-1. I-Steam egcwele i-Steam kunye neSteam eguqukayo inolwalamano olwahlukileyo kunye noxinzelelo.
I-Steam egxunyelweyo i-steam ifunyenwe ngqo ukusuka emanzini ashushu. Iqondo lobushushu, uxinzelelo, kunye nokuxinana komtya ogcwele Iqondo lokushisa eliphantsi koxinzelelo olufanayo lwemozulu yi-100 ° C. Ukuba iqondo lokushisa eliphezulu elinobushushu liyafuneka, yandisa nje uxinzelelo lweSteam.
I-Steam eguqukayo iphinde yahlaziywa isitya esigxekayo, oko kukuthi, i-steam iveliswe ngu-Heat.superseharsehand Steam i-Gaam igcwaliswe, kodwa iqondo layo liyanda kunye nokunyuka kwayo.

I-2. I-Steam egqwesileyo kunye ne-Steam eguqukayo isebenzisa izixhobo ezahlukeneyo
I-Steam eguqukayo isetyenziswa ngokubanzi kwizityalo zamandla e-thermal ukuqhuba iiturbines ze-steam ukuvelisa umbane.
I-Steam egxunyelweyo isetyenziselwa izixhobo zokufudumeza okanye ukutshintshiselana ubushushu.

3. Utshintshelo lotshintshiselwano lobushushu lwe-Steam egxunyelweyo kunye ne-Steam eguqukayo yahlukile.
Ukudluliselwa kobushushu kwe-Steam eguqukayo iphantsi kune-steam egcwelekileyo.
Ke ngoko, ngexesha lenkqubo yokuveliswa, i-steam ebalaseleyo kufuneka iguqulwe ibe yi-steam egcweleyo ngokunciphisa ubushushu kunye noxinzelelo ukunciphisa ukusetyenziswa kwakhona.
Isikhundla sokufakelwa kwe-Desuercheater kunye neCorance Decer ngokubanzi kwindawo engaphambili ye-Steam-esebenzisa izixhobo zokuhamba kunye nokuphela kwesilinda. Inokubonelela nge-steam egcweleyo ye-Steam eyodwa okanye emininzi esebenzisa i-Steam-usebenzisa izixhobo zokusebenza.
