Ungasusa kanjani ngokwesayensi ku-Scale from Steam Generator?

Isikali sisongela ngokuqondile ukuphepha nokuphila kwensiza yedivaysi ye-Steam Generator ngoba ukuthuthuka okushisayo kwesilinganiso kuncane kakhulu. Ukuvuselelwa okushisayo kwesilinganiso kungamakhulu ezikhathi ezincane kunalezo zensimbi. Ngakho-ke, noma ngabe kungakabikwa kakhulu esikalini esishisayo, ukusebenza kahle kokushisa kuzoncishiswa ngenxa yokumelana okukhulu okushisayo, okuphumela ekulahlekelweni kokushisa kanye nokungcola kukaphethiloli kanye nokungcola kukaphethiloli.

Ukuzijwayeza kufakazele ukuthi i-1mm yesilinganiso endaweni yokushisa ye-Steam generator ingakhuphula ukusetshenziswa kwamalahle cishe cishe ku-1.5 ~ 2%. Ngenxa yesilinganiso endaweni yokushisa, udonga lwensimbi yensimbi luzokwenyanyelwa ngokwengxenye. Lapho izinga lokushisa lodonga lidlula izinga lokushisa elivumelekile elilinganiselayo, ipayipi lizongenza bushe, okungenze ukuba angenze kabi ingozi yokuqhuma kwamapayipi futhi asongele ukuphepha komuntu siqu. Isikali kungusawoti onzima oqukethe ama-halogen oon asola ama-corlodes amazinga okushisa aphezulu.

Ngokuhlaziywa kwesilinganiso sensimbi, kungabonakala ukuthi okuqukethwe kwayo kwensimbi kucishe kube ngu-20 ~ 30%. Ukuguguleka kwesikali sensimbi kuzodala ukuthi udonga lwangaphakathi lwe-generator ye-steam ukuze lube brittle ne-corrode kujule. Ngenxa yokuthi ukususa isikali kudinga ukuvala isithando somlilo, kudliwa amandla kanye nezinsizakusebenza ezibonakalayo, futhi kubangela ukulimala kwemishini kanye nokugqwala kwamakhemikhali.

I-Nobeth Steam Generator inokuqapha okuzenzakalelayo okuzenzakalelayo kanye ne-alamu yedivayisi. Kukala ukukala odongeni lwamapayipi ngokubheka izinga lokushisa lomzimba. Lapho kunokucaca okuncane ngaphakathi kwe-boiler, kuzokwenza i-alamu ngokuzenzakalela. Lapho ukukala kunzima, kuzophoqeleka ukuthi kuvalwe phansi ukugwema ukukala. Ingozi yokuqhuma kwepayipi ingcono inweba impilo yenkonzo yemishini.

Lapho kunesilinganiso noma i-slag esithandweni somlilo, hlikihla amanzi esikela umlilo ngemuva kokuvalela isithando somlilo ukupholisa i-generator ye-Steam, bese uyiphonsa ngamanzi noma usebenzise ibhulashi lentambo eliwukuyisusa. Uma isikali silukhuni, singahlanzwa nge-pig pig eqhutshwa yi-jet yokuhlanza amanzi aphezulu noma ama-hydraulic. Le ndlela ilungele kuphela amapayipi ensimbi futhi ayilungele ukuhlanza amapayipi ethusi ngoba ihlanza ipayipi lingalimaza kalula amapayipi ethusi.

2. Indlela evamile yokususa amakhemikhali
Ngokusho okubonakalayo kwemishini, khetha i-ejenti yokuhlanza ephephile futhi enamandla ezayo. Ngokuvamile, ukugxila kwesixazululo kulawulwa ku-5 ~ 20%, okunganqunywa ngokuya ngobukhulu besilinganiso. Ngemuva kokuhlanza, qala ukhulule uketshezi lwemfucuza, bese uhlanza ngamanzi ahlanzekile, bese ugcwalisa amanzi, engeza i-newrarizer eno-3% wamandla amanzi, ngemuva kokukhipha uketshezi oluyinsalela, geza kanye noma kabili ngamanzi ahlanzekile.

Ukuklama ukwakhiwa kwe-generator ye-Steam kuyingozi enkulu. I-Drainage ejwayelekile ne-Descaling iyadingeka ukuqinisekisa ukusebenza okujwayelekile kwe-Steam Generator.
