20G high pressure boiler chubu kukhazikitsa muyezoGB5310-2008kuchuluka kwa ntchito, kumagwiritsidwa ntchito popanga kuthamanga kwambiri komanso pamwamba pa kuthamanga kwamadzi chubu chotenthetsera chotenthetsera pamwamba ndi chitsulo chamtundu wapamwamba kwambiri, chitsulo cha aloyi ndi chubu chosapanga dzimbiri chachitsulo chosapanga dzimbiri. Kuthamanga kwambiri kwa boilers kopanda chitsulo chubu ndi mtundu wa chubu cha boiler, chifukwa chubu cha 20G chopopera nthawi zambiri chimagwiritsidwa ntchito pa kutentha kwambiri komanso kupanikizika kwambiri, chubuchi chimachitika chifukwa cha kutentha kwambiri kwa gasi ndi nthunzi wamadzi, makutidwe ndi okosijeni ndi dzimbiri zidzachitika. Chitoliro chachitsulo chimafunika kuti chikhale ndi mphamvu zolimba kwambiri, kukana kwa kutukuta kwa okosijeni komanso kukhazikika kwa microstructure. Chubu cha boiler chothamanga kwambiri chimagwiritsidwa ntchito kwambiri popanga kupanikizika kwambiri komanso kopitilira muyeso kotentha kotentha kotentha, chubu chotenthetsera, chitoliro, chubu chachikulu cha nthunzi, ndi zina. Pogwira ntchito ya chubu chachitsulo chosasunthika, mulingo wamadzi womwe watchulidwa uyenera kusungidwa mumtambo, kupanikizika sikuyenera kupitilira kukakamiza kwa boiler, ogwira ntchito ku boiler nthawi zambiri amayenera kuyang'anira kuwunika kwa nthunzi. Chitoliro cha boiler chikadzadza ndi madzi, chiyenera kutsanulidwa mu nthawi kuti muyimitse co-hydrating ndi kubwezeretsa mlingo wa madzi. Pambuyo poyimitsa ng'anjo, madziwo atakhazikika kwa nthawi yayitali mpaka pansi pa madigiri 70, madzi a ng'anjo amatha kumasulidwa, ndiyeno madzi opangira mankhwala opangira madzi engase angagwiritsidwe ntchito ukonde utatha. Kuthamanga kwambiri kotentha kotentha kopanda chitsulo kumagwiritsidwa ntchito makamaka popanga kupanikizika kwambiri komanso kopitilira muyeso kotentha kotentha kotentha kwambiri, chubu chotenthetsera, chitoliro, chitoliro chachikulu cha nthunzi, ndi zina zotere. Mtundu wa boiler chubu malinga ndi momwe kutentha kumagwirira ntchito umagawidwa mu chubu cha boiler ndi chubu cha boiler chothamanga kwambiri.
