Kwenzeka ntoni kwijenereyitha yomphunga ngaphandle kokucocwa kwamanzi?

Isishwankathelo: Kutheni iijenereyitha zomphunga zifuna unyango lokusasazwa kwamanzi

Iijenereyitha zomphunga zineemfuno eziphezulu zomgangatho wamanzi. Xa kuthengwa i-generator ye-steam kunye nokuyibeka kwimveliso, unyango olungafanelekanga lomgangatho wamanzi wendawo luya kuchaphazela ubomi bejeneretha ye-steam, kwaye unyango lwamanzi luya kuthoba amanzi.

Ukufakela kunye nokusebenzisa i-generator ye-steam, kufuneka ixhotyiswe nge-softener yamanzi. Yintoni into yokuthambisa amanzi? I-softener yamanzi yi-sodium ion exchanger, ethambisa amanzi anzima kwiimfuno zemveliso. Iqukethe itanki yeresin, itanki yetyuwa, kunye nevalve yokulawula. Yintoni ingozi eya kwenzeka ukuba amanzi awacocwa?

1. Ukuba umgangatho wamanzi wendawo awuqinisekanga, ukuba unyango lwamanzi alusetyenziswanga, isikali siya kwenza lula ngaphakathi, sinciphise kakhulu ukusebenza kwe-thermal ye-generator ye-steam;
2. Isikali esigqithisileyo siya kwandisa ixesha lokufudumeza kunye nokwandisa iindleko zamandla;
3. Umgangatho ombi wamanzi unokutshabalalisa ngokulula iindawo zetsimbi kwaye unciphise ubomi bejenereyitha yomphunga;
4. Kukho isikali esikhulu kakhulu kwimibhobho yamanzi. Ukuba ayicocwanga ngexesha, iya kuthintela imibhobho kwaye ibangele ukujikeleza kwamanzi okungaqhelekanga.

Xa ubumdaka obusemanzini buzele kumanzi enjini, bunokugqwala ngenxa yezinto eziqinileyo. Ukuba i-paroxysmal solid matter ixhonywe emanzini e-injini, ibizwa ngokuba ludaka; ukuba ibambelela kwiindawo ezifudumeleyo, ibizwa ngokuba yi-scale. Ijenereyitha yomphunga ikwasisixhobo sokutshintsha ubushushu. I-fouling iya kuba nefuthe elikhulu ekugqithiseni ukushisa kwejenereyitha yomphunga. I-thermal conductivity ye-fouling isinye seshumi ukuya kumakhulu amaxesha entsimbi.

Ke ngoko, iinjineli zobugcisa zeNobeth ziyakucebisa abathengi ukuba basebenzise isithambisa samanzi. Isithambisi samanzi sinokuhluza ngokufanelekileyo i-calcium kunye ne-magnesium ion emanzini, ivumela ijenereyitha yomphunga ukuba isebenze kwindawo efanelekileyo.

Ukuze ungachaphazeli ukusetyenziswa kwejeneretha ye-steam, isethi yokuthambisa amanzi ixhotyiswe. Amanzi athambileyo anokunciphisa ukubola kwesinyithi kwaye akhulise kakhulu ubomi benkonzo yejeneretha ye-steam. Iprosesa yamanzi idlala indima enkulu kwijenereyitha yomphunga wombane. Iprosesa yamanzi yenye yeekhonkco ezibalulekileyo zokuqinisekisa ukusebenza okuqhelekileyo kwejenereyitha yomphunga.

Ke ngoko, ukukala kwejenereyitha yomphunga kunokubangela ezi ngozi zilandelayo:

1. Inkunkuma yamafutha
Emva kokuba i-generator ye-steam ihlanjululwe, umsebenzi wokufudumeza ubushushu bomhlaba wokufudumeza uba yimbi, kwaye ukushisa okukhutshwe ngokutshiswa kwamafutha akukwazi ukudluliselwa kumanzi kwijeneretha ngexesha. Ubungakanani obukhulu bobushushu buthathwa yigesi ye-flue, ebangela ukuba ubushushu bokukhupha bube phezulu kakhulu. Ukuba i-gas yokukhupha ilahlekile kwaye yanda, amandla okushisa e-generator ye-steam aya kuncitshiswa, kwaye malunga ne-1mm yesikali iya kuchitha i-10% yamafutha.

2. Umphezulu wokufudumeza wonakaliswe
Ngenxa yokungasebenzi kakuhle kokuhanjiswa kobushushu bejenereyitha ye-steam, ukushisa kwe-fuel ukutshisa akukwazi ukuhanjiswa ngokukhawuleza kumanzi e-generator, okubangelwa ukwanda kwesithando somlilo kunye nokushisa kwegesi ye-flue. Ngoko ke, ukuhluka kweqondo lokushisa kumacala omabini omgangatho wokufudumala kwandisa, ukushisa kwodonga lwetsimbi kwandisa, amandla ayancipha, kwaye udonga lwentsimbi luqhuma okanye luqhume phantsi koxinzelelo lwejeneretha.
