Ungawususa njani ubungakanani ngokwesayensi kwiimveliso ze-Steam?

Isikali sisongela ngokuthe ngqo ukhuseleko kunye nenkonzo yobomi be-Steam ye-Steam kuba i-thermal yokuphumelela kwesikali incinci kakhulu. Ukuqhutywa komgangatho kwinqanaba lamaxesha amancinci elincinci kuneso sinyithi. Ke ngoko, nokuba akukho sikali sikhulu senziwe kumphezulu wokufudumeza, ukuqulunqwa kobushushu kuya kuncitshiswa ngenxa yokungaxhathisi esikhulu se-shirmal, okukhokelela kwinkcitho ye-oyile.

Ukuziqhelanisa kubonakalise ukuba i-1mm yenqanaba kumphezulu wokufudumeza womvelisi we-steam inokunyusa ukusetyenziswa kwe-COAL malunga ne-1.5 ~ 2%. Ngenxa yesikali kumphezulu wokufudumeza, udonga lombhobho wentsimbi luya kubhalwa ngokuyinxenye. Xa ubushushu bodonga bugqitha ubushushu obuvunyiweyo wokusebenza, umbhobho uya kuxhuzula, onokuthi ubangele ukuqhuma kwengozi kwaye usongele ukhuseleko lobuqu. Isikali yityuwa entsokothileyo ene-halogn iion ezibonisa i-iron inyibilikisi kubushushu obuphakamileyo.

Ngohlalutyo lwesilinganiselo sentsimbi, sinokubonwa ukuba umxholo wayo wentsimbi uneminyaka engama-20 ~ 30%. Ukhukuliseka kwesinyithi kuya kubangela udonga olungaphakathi lomvelisi weSteam ukuba ube brittle kwaye ubongoze nzulu. Kuba ukususa kwinqanaba kufuna ukucima iziko, kutya i-manpower kunye nezixhobo ezibonakalayo, kwaye zibangela ukonakala koomatshini kunye nokususwa kweekhemikhali.

Umthengisi we-nobbeth Steam unesixhobo esizenzekelayo sokujonga ngokuzenzekelayo kunye nesixhobo se-alam. Ilinganisa ukuqhekezwa kudonga lombhobho ngokubeka iliso kubushushu bomzimba obunqabileyo bomzimba. Xa kukho ukoyila kancinci ngaphakathi kwi-boiler, iya kuvusa ngokuzenzekelayo. Xa sukulukuphiko lunzima, kuya kunyanzeleka ukuba uvale phantsi ukuze uphephe ukuphilisa. Umngcipheko wokuphefumla uqhume ngakumbi ubonakale kwinkonzo yenkonzo yezixhobo.

I-1. Indlela yokuLawulwa koMatshini
Xa kukho isikali okanye i-slag kwiziko, lamba amanzi lesithando emva kokuvala iziko lokupholisa i-generator, emva koko iqhube ngamanzi okanye isebenzise ibrashi ye-spire ibrashi yokuyisusa. Ukuba isikali sinzima kakhulu, sinokucocwa nge-pig ye-pig eqhutywa yi-jet ye-jet ephezulu yejeet okanye i-hydraulic amandla. Le ndlela ilungele kuphela imibhobho yentsimbi kwaye ayifanelekanga ekucoceni imibhobho yobhedu kuba umcoci wepayike unokuyonakalisa ngokulula imibhobho yobhedu.

I-2. Indlela eqhelekileyo yokukhupha izikali
Ngokwemixholo yezixhobo, khetha iarhente yokucoca ekhuselekileyo nenamandla. Ngokubanzi, ugxininiso lwesisombululo lulawulwa kwi-5 ~ 20%, elinokugqitywa ngokobukhulu besikali. Emva kokucocwa, khupha ulwelo lwenkunkuma, emva koko hlamba ngamanzi acocekileyo, emva koko gcwalisa amanzi, yongeza i-3% ye-0,51, i-cubiling kube kanye okanye kabini ngamanzi acocekileyo.

Ukuqala kokwakha kwi-Steam Generator kuyingozi kakhulu. I-subrage rhoqo kunye nokuphola kuyafuneka ukuqinisekisa ukusebenza kwesiqhelo komphunga weSteam.
