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 choponderezedwa kwambiri chimagwiritsidwa ntchito kwambiri popanga machubu othamanga kwambiri komanso okwera kwambiri, chubu chotenthetsera, chitoliro, chubu chachikulu cha nthunzi, ndi zina zambiri. The kuwira, kupsyinjika sayenera kupitirira kukanikiza kukatentha ntchito, kukatentha antchito nthawi zambiri kuwunika nthunzi kuthamanga gauge. 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. Chubu chachitsulo chosakanizidwa chokwera kwambiri chimagwiritsidwa ntchito kwambiri popanga kupanikizika kwambiri komanso kopitilira muyeso wapamwamba kwambiri wotenthetsera chubu, chubu chotenthetsera, chitoliro, chitoliro chachikulu cha nthunzi, ndi zina. Mtundu wa boiler chubu malinga ndi momwe kutentha kumagwirira ntchito umagawidwa mu chubu chowotcha wamba komanso kuthamanga kwambiri. boiler chubu.
