M'zaka zaposachedwa, ndi chitukuko chofulumira chachuma, kufunikira kwa ma boilers kwawonjezekanso.Pa ntchito ya tsiku ndi tsiku ya boiler, imagwiritsa ntchito mafuta, magetsi ndi madzi.Pakati pawo, kugwiritsa ntchito madzi opopera sikungokhudzana ndi kuwerengera ndalama, komanso kumakhudzanso kuwerengera kwa madzi a boiler.Panthawi imodzimodziyo, kubwezeretsanso madzi ndi kutulutsa zimbudzi za boiler zimagwira ntchito yofunika kwambiri pakugwiritsa ntchito boiler.Chifukwa chake, nkhaniyi ikambirana nanu zina zokhudzana ndi kugwiritsa ntchito madzi a boiler, kubwezeretsanso madzi, komanso kutulutsa zimbudzi.
Njira yowerengera kusuntha kwa boiler
Njira yowerengera yogwiritsira ntchito madzi a boiler ndi: kumwa madzi = kutentha kwa boiler + nthunzi ndi kutaya madzi
Zina mwa izo, njira yowerengera ya nthunzi ndi kutaya madzi ndi: kutayika kwa nthunzi ndi madzi = kutaya kwa boiler + kutayika kwa payipi ndi kutaya madzi.
Kuphulika kwa boiler ndi 1 ~ 5% (zokhudzana ndi khalidwe la madzi), ndipo nthunzi yamapaipi ndi kutaya madzi nthawi zambiri zimakhala 3%
Ngati madzi osungunulidwa sangathe kubwezeredwa pambuyo pa nthunzi yotenthetsera, kuthira madzi pa 1t imodzi ya nthunzi = 1+1X5% (5% pakutaya kutayika) + 1X3% (3% pakutayika kwa mapaipi) = 1.08t yamadzi
Kubwezeretsanso madzi a boiler:
M'ma boilers a nthunzi, nthawi zambiri, pali njira ziwiri zowonjezeretsanso madzi, zomwe ndi kubwezeretsanso madzi pamanja ndi kubwezeretsanso madzi.Pofuna kubwezeretsanso madzi pamanja, wogwiritsa ntchitoyo amayenera kupanga ziganizo zolondola potengera kuchuluka kwa madzi.Kubwezeretsanso madzi kwamadzi kumachitika ndi kuwongolera kwamadzi okwera komanso otsika.Kuonjezera apo, ponena za kubwezeretsa madzi, pali madzi otentha ndi ozizira.
Madzi a boiler:
Ma boilers a nthunzi ndi ma boilers amadzi otentha amakhala ndi ma blowdown osiyanasiyana.Ma boiler a nthunzi amakhala ndi kuphulika kosalekeza komanso kuphulika kwapakatikati, pomwe ma boiler amadzi otentha amakhala ndi kuphulika kwapakatikati.Kukula kwa chowotchera ndi kuchuluka kwa kuphulika kumafotokozedwa muzofotokozera za boiler;kumwa madzi pakati pa 3 ndi 10% kumadaliranso malingana ndi cholinga cha boiler, mwachitsanzo, ma boilers otenthetsera amaganizira kwambiri kutayika kwa mapaipi.Kuchokera ku mapaipi atsopano kupita ku mapaipi akale akhoza kukhala 5% mpaka 55%.Kuthamanga kosasinthasintha ndi kuphulika panthawi yokonzekera madzi ofunda kutengera njira yomwe imatengedwa.Madzi obwerera kumbuyo amatha kukhala pakati pa 5% ndi 5%.Sankhani pakati pa ~ 15%.Zachidziwikire, ena amagwiritsa ntchito reverse osmosis, ndipo kuchuluka kwa zimbudzi kudzakhala kochepa kwambiri.
Kukhetsa kwa boiler komwe kumaphatikizapo ngalande zokhazikika komanso ngalande zosalekeza:
Kutulutsa mosalekeza:Monga momwe dzinalo likusonyezera, kumatanthauza kutuluka kosalekeza kudzera mu valavu yotseguka, makamaka kutulutsa madzi pamwamba pa ng'oma yapamwamba (ng'oma ya nthunzi).Chifukwa chakuti mchere wa gawo ili lamadzi ndi wochuluka kwambiri, umakhudza kwambiri khalidwe la nthunzi.Kutulutsa kumeneku kumatengera pafupifupi 1% ya mpweya.Nthawi zambiri imalumikizidwa ndi chotengera chokulitsa chopitilira kuti chibwezeretse kutentha kwake.
Kutulutsa komwe kwakonzedwa:kumatanthauza kutulutsa zimbudzi pafupipafupi.Imatulutsa dzimbiri, zonyansa, ndi zina zambiri pamutu (bokosi lamutu).Mtundu wake nthawi zambiri umakhala wofiirira.Voliyumu yotulutsa ndi pafupifupi 50% ya kutulutsa kokhazikika.Imalumikizidwa ndi chotengera chowonjezera chotsitsa kuti muchepetse kuthamanga ndi kutentha.
