Amanzi ngumthombo ongundoqo wokuqhuba ubushushu kwiijenereyitha zomphunga. Ke ngoko, unyango lwamanzi olwenziwa ngumphunga kwishishini ludlala indima ebalulekileyo ekuqinisekiseni ukusebenza kakuhle, uqoqosho, ukhuseleko, kunye nokusebenza kweejenereyitha zomphunga. Idibanisa imigaqo yokucocwa kwamanzi, amanzi ajikisiweyo, amanzi okuzenzela, kunye nokunciphisa ukuxhathisa kwe-thermal. Kwimiba emininzi, yazisa ifuthe lonyango lwamanzi lwe-steam jenereyitha kusetyenziso lwamandla ejenereyitha yomphunga.
Umgangatho wamanzi unempembelelo ebalulekileyo ekusetyenzisweni kwamandla kwiijenereyitha zomphunga. Iingxaki zomgangatho wamanzi ezibangelwa kunyango olungafanelekanga lwamanzi zihlala zikhokelela kwiingxaki ezinjengokulinganisa, ukubola, kunye nokunyuka kwesantya sokukhutshelwa kwamanzi amdaka kwijenereyitha yomphunga, okukhokelela ekunciphiseni ukusebenza kakuhle kwe-thermal yejenereyitha yomphunga, kunye nokusebenza kakuhle kwe-thermal yejenereyitha yomphunga Ngamnye. ipesenti yokunciphisa ipesenti iya kwandisa ukusetyenziswa kwamandla nge-1.2 ukuya kwi-1.5.
Okwangoku, unyango lwamanzi lwe-steam generator lwasekhaya lunokwahlulwa lube ngamanyathelo amabini: ukucocwa kwamanzi ngaphandle kwembiza kunye nokucocwa kwamanzi ngaphakathi embizeni. Ukubaluleka kokubini kukuphepha ukubola kunye nokunyuka kwejenereyitha yomphunga.
Ugxininiso lwamanzi angaphandle kwebhodwe kukuthambisa amanzi kunye nokususa ukungcola okufana ne-calcium, i-oksijini, kunye neetyuwa ezinobunzima be-magnesium ezibonakala kumanzi akrwada ngokusebenzisa iindlela zonyango, iikhemikhali kunye ne-electrochemical; ngelixa amanzi angaphakathi ebhodweni esebenzisa amayeza amashishini njengendlela yonyango esisiseko.
Ukulungiswa kwamanzi ngaphandle kwebhodwe, eyona nxalenye ebalulekileyo yonyango lwamanzi e-steam generator, kukho izigaba ezintathu. Indlela yokutshintshiselana nge-sodium ion esetyenziswa kunyango lwamanzi oluthambileyo inokunciphisa ubunzima bamanzi, kodwa i-alkalinity yamanzi ayinakuncitshiswa ngakumbi.
I-Steam generator scaling inokwahlulwa ibe yisulfate, carbonate, silicate scale kunye nesikali esixubileyo. Xa kuthelekiswa nentsimbi eqhelekileyo yentsimbi yejenereyitha yomphunga, ukusebenza kwayo kokufudumeza ubushushu kukuphela kwe-1/20 ukuya kwi-1/240 yokugqibela. Ukucocwa kuya kunciphisa kakhulu ukusebenza kokufudumeza ubushushu bejenereyitha yomphunga, okubangela ukuba ubushushu bomlilo buthathwe ngumsi wokuphuma, okukhokelela ekuncipheni kwemveliso yejenereyitha yomphunga kunye nomgangatho womphunga. Ukungcola kwe-Lmm kuya kubangela i-3% ukuya kwi-5% yelahleko yegesi.
Indlela yokutshintshiselana nge-sodium ion okwangoku esetyenziswa ekuthobeni unyango kunzima ukufezekisa injongo yokususwa kwe-alkali. Ukuze kuqinisekiswe ukuba amacandelo oxinzelelo alugqwali, iijenereyitha zomphunga kwi-industrial kufuneka zilawulwe ngokukhutshwa kwamanzi amdaka kunye nokucocwa kwamanzi ebhodweni ukuqinisekisa ukuba i-alkalinity yamanzi akrwada ifikelela kumgangatho.
Ke ngoko, izinga lokukhutshelwa kwelindle kwizijenereyitha zomphunga kwimizi-mveliso yasekhaya lihlala lihleli phakathi kwe-10% kunye ne-20%, kwaye rhoqo nge-1% yokonyuka kwezinga lokukhutshelwa kwelindle kuya kubangela ukuba ilahleko yamafutha inyuke nge-0.3% ukuya kwi-1%, nto leyo enciphisa kakhulu ukusetyenziswa kwamandla ombane. iijenereyitha zomphunga; okwesibini, Ukonyuka komxholo wetyuwa womphunga obangelwa kukuphuphuma ngokubambisana kwesoda kunye namanzi kuya kubangela umonakalo wesixhobo kunye nokwandisa ukusetyenziswa kwamandla kwejenereyitha yomphunga.
Ukuchatshazelwa yinkqubo yemveliso, iijenereyitha zomphunga kwimizi-mveliso ezinomthamo omkhulu zihlala zifuna ukufakela i-thermal deaerator. Kukho iingxaki eziqhelekileyo kwisicelo sayo: ukusetyenziswa komthamo omkhulu we-steam kunciphisa ukusetyenziswa ngokufanelekileyo kobushushu bejeneretha ye-steam; Umahluko weqondo lobushushu phakathi konikezelo lwamanzi lobushushu bejenereyitha kunye ne-avareji yobushushu bamanzi botshintshiselwano lobushushu uba mkhulu, okukhokelela ekonyukeni kokulahleka kobushushu.
