Ingakanani ingozi isikali esiyenza kumajeneretha esitimu? Ungakugwema kanjani?

Ijeneretha yesitimu iyibhayela engenawo yokuhlola enomthamo wamanzi ongaphansi kuka-30L. Ngakho-ke, izidingo zekhwalithi zamanzi ze-steam generator kufanele zisetshenziswe ngokuhambisana nezidingo zekhwalithi yamanzi ye-boiler ye-steam. Noma ubani oke wathintana ne-boiler uyazi ukuthi amanzi abhayela ahlukile emanzini ajwayelekile futhi kufanele athole ukwelashwa okukhethekile okuthambisa. Amanzi angathambile athambekele ekukhiqizeni isikali, futhi isikali sizodala ukulimala okuningi kubhayela. Ake ngihlanganyele nawe imiphumela yesikali ku-steam. Yiziphi izingozi eziyinhloko zamajeneretha?

1. Kulula ukubangela ukuguqulwa kwensimbi kanye nomonakalo ovuthayo.
Ngemuva kokuthi i-generator ye-steam ilinganisiwe, kuyadingeka ukugcina ingcindezi ethile yokusebenza kanye nevolumu yokuhwamuka. Okuwukuphela kwendlela ukukhulisa izinga lokushisa lomlilo. Kodwa-ke, ukuqina kwesikali, i-conductivity ephansi ye-thermal, iphakamisa izinga lokushisa lomlilo, futhi insimbi izogxuma ngenxa yokushisa ngokweqile. Ukuguqulwa kungabangela kalula ukushiswa kwensimbi.

2. Ukumosha uphethiloli wegesi
Ngemuva kokuthi i-generator ye-steam ilinganisiwe, ukuqhutshwa kwe-thermal kuzoba mpofu, futhi ukushisa okuningi kuzosuswa yi-flue gas, okubangela ukushisa kwegesi ephumayo ibe phezulu kakhulu futhi amandla okushisa we-generator ye-steam ayancipha. Ukuze kuqinisekiswe ukucindezelwa nokuhwamuka kwejeneretha ye-steam, uphethiloli owengeziwe kufanele wengezwe, ngaleyo ndlela kumoshwe uphethiloli. Cishe i-1 mm yesikali izomosha uphethiloli ongu-10%.

3. Fushanisa impilo yesevisi
Ngemva kokukalwa kwejeneretha yesitimu, isikali siqukethe ama-halogen ions, agqwalisa insimbi emazingeni okushisa aphakeme, enze udonga lwangaphakathi lwensimbi lube brittle, futhi luqhubeke lukhula lujule odongeni lwensimbi, lubangele ukugqwala kwensimbi futhi lufinyeze ukukhiqizwa kwesitimu. impilo yesevisi yedivayisi.

4. Khulisa izindleko zokusebenza
Ngemuva kokuthi i-generator ye-steam isikali, kufanele ihlanzwe ngamakhemikhali afana ne-asidi ne-alkali. Uma isikali sishubile, kudliwa amakhemikhali amaningi futhi kutshalwa imali eyengeziwe. Noma ngabe ukwehliswa kwamakhemikhali noma ukuthenga izinto ezizokhandwa, kusetshenziswe abasebenzi abaningi, impahla kanye nezinsiza zezimali.

Kunezindlela ezimbili zokwelashwa kokukala:

1. Ukwehliswa kwamakhemikhali.Engeza ama-agent okuhlanza amakhemikhali ukuze uhlakaze futhi ukhiphe ukugqwala okuntantayo, isikali namafutha emishinini, ukubuyisela indawo yensimbi ehlanzekile. Lapho ukwehla kwamakhemikhali, udinga futhi ukunaka inani elingu-PH le-ejenti yokuhlanza. Akufanele kube phezulu kakhulu noma phansi kakhulu, ngaphandle kwalokho isikali singase singahlanjululwa ngokuhlanzekile noma udonga lwangaphakathi lwejeneretha ye-steam lungalimala.

2. Faka okokuthambisa amanzi.Uma ubulukhuni bamanzi bejeneretha ye-steam buphakeme, kunconywa ukusebenzisa iprosesa yamanzi ethambile, engahlunga ngokuphumelelayo i-calcium ne-magnesium ion emanzini, isebenze ikhwalithi yamanzi, futhi igweme ukwakheka kwesikali kamuva.
Kafushane, umonakalo odalwe isikali kumajeneretha omusi nezindlela zokwelashwa zesikali ziyafingqwa. Isikali “siwumthombo wamakhulu ezingozi” zamajeneretha omusi. Ngakho-ke, ngesikhathi sokusetshenziswa kwemishini, indle kufanele ikhishwe ngaphansi kwengcindezi ngesikhathi ukuze kugwenywe ukukhiqizwa kwesikali nokuqeda izingozi. Kuzosiza futhi ukonga ukusetshenziswa kwamandla futhi kunwebe impilo yesevisi yejeneretha yesitimu.
