20G:GB5310Chitsulo chovomerezeka cha -95 (chinthu chachilendo chofanana: ST45.8 ya ku Germany, STB42 ya ku Japan, United States SA106B), ndiye chitoliro chachitsulo cha boiler chomwe chimagwiritsidwa ntchito kwambiri, kapangidwe ka mankhwala ndi mawonekedwe a makina ndipo mbale 20 ndizofanana. Chitsulocho chili ndi mphamvu inayake kutentha kwa chipinda ndi kutentha kwapakati, mpweya wochepa, pulasitiki wabwino komanso kulimba, kupanga kwake kotentha ndi kozizira komanso magwiridwe antchito ake ndi abwino. Chimagwiritsidwa ntchito kwambiri popanga zinthu zotenthetsera zotenthetsera zotentha kwambiri komanso zapamwamba, chotenthetsera chotsika kutentha, chotenthetsera, chotenthetsera ndi khoma lamadzi, ndi zina zotero. Monga kutentha kwa khoma la chitoliro chaching'ono ≤500℃, ndi chitoliro cha khoma lamadzi, chubu cha economizer, kutentha kwa khoma la chitoliro chachikulu ≤450℃, bokosi losonkhanitsira (chotenthetsera, khoma lamadzi, chotenthetsera chotsika kutentha ndi bokosi lolumikizira chotenthetsera), zida zapaipi zapakati ≤450℃. Chifukwa chitsulo cha kaboni chimapanga graphitization pakapita nthawi yayitali kuposa 450℃, kotero kutentha kwakukulu kwa nthawi yayitali kwa chitoliro chotenthetsera pamwamba kumakhala kochepera 450℃. Chitsulo chomwe chili mu kutentha kumeneku, mphamvu yake imatha kukwaniritsa zofunikira za superheater ndi payipi ya nthunzi, ndipo chili ndi kukana kwabwino kwa okosijeni, pulasitiki, kulimba, katundu wowotcherera ndi zinthu zina zozizira komanso zotentha zomwe zimagwiritsidwa ntchito kwambiri, zimagwiritsidwa ntchito kwambiri. Zigawo za chitsulo zomwe zimagwiritsidwa ntchito mu ng'anjo ya ku Iran (kutanthauza seti imodzi) ndi chitoliro cholowera madzi (matani 28), chitoliro cholowera madzi (matani 20), chitoliro cholumikizira nthunzi (matani 26), chidebe cha economizer (matani 8), ndi makina ochepetsera madzi (matani 5), ndipo zina zonse zimagwiritsidwa ntchito ngati chitsulo chathyathyathya ndi zipangizo zodulira (pafupifupi matani 86).

Sa-210c (25MnG) : Nambala yachitsulo muASME SA-210muyezo. Ndi chubu chaching'ono cha chitsulo cha carbon manganese chokhala ndi mainchesi awiri cha ma boiler ndi ma superheater, komanso chitsulo champhamvu chotentha chokhala ndi mawonekedwe a ngale. Mu 1995, chinasamutsidwa ku GB5310 ndipo chinatchedwa 25MnG. Kapangidwe kake ka mankhwala ndi kosavuta, kupatula kuchuluka kwa kaboni ndi manganese, zina zonse ndizofanana ndi 20G, kotero mphamvu yokolola ndi pafupifupi 20% kuposa 20G, ndipo pulasitiki ndi kulimba kwake ndizofanana ndi 20G. Njira yopangira chitsulo ndi yosavuta ndipo magwiridwe antchito ake ozizira komanso otentha ndi abwino. Kugwiritsa ntchito m'malo mwa 20G, kumatha kuchepetsa makulidwe a khoma, kuchepetsa kuchuluka kwa zipangizo, komanso kumatha kusintha kutentha kwa boiler. Zigawo zake zogwiritsira ntchito ndi kutentha kogwiritsidwa ntchito ndizofanana ndi 20G, zomwe zimagwiritsidwa ntchito makamaka kutentha kogwira ntchito pansi pa 500℃ khoma lamadzi, economizer, superheater yotsika kutentha ndi zina.
Sa-106c: Ndi nambala yachitsulo muASME SA-106muyezo. Ndi chubu chachitsulo cha kaboni-manganese cha ma boiler akuluakulu ndi ma superheaters otentha kwambiri. Kapangidwe kake ka mankhwala ndi kosavuta, kofanana ndi chitsulo cha kaboni cha 20G, koma kuchuluka kwa kaboni ndi manganese ndikokwera, kotero mphamvu yake yobereka ndi pafupifupi 12% kuposa 20G, ndipo kulimba kwa pulasitiki sikoipa. Njira yopangira chitsulo ndi yosavuta ndipo magwiridwe antchito ake ozizira komanso otentha ndi abwino. Pogwiritsa ntchito m'malo mwa 20G wopanga (economizer, khoma loziziritsa madzi, superheater yotsika kutentha ndi bokosi lolumikizira lobwezeretsanso), makulidwe a khoma amatha kuchepetsedwa ndi pafupifupi 10%, zomwe sizingangopulumutsa mtengo wazinthu zokha, komanso kuchepetsa ntchito yowotcherera, ndikuwonjezera kusiyana kwa kupsinjika bokosi lolumikizira likayamba.
15Mo3 (15MoG): Ndi chitoliro chachitsulo mu DIN17175 standard. Ndi chubu chachitsulo cha carbon molybdenum chaching'ono cha m'mimba mwake cha boiler ndi superheater, komanso chitsulo champhamvu chotentha cha mtundu wa pearlescent. Mu 1995, chinasamutsidwa ku GB5310 ndipo chinatchedwa 15MoG. Kapangidwe kake ka mankhwala ndi kosavuta, koma kali ndi molybdenum, kotero kali ndi mphamvu yabwino yotenthetsera kuposa chitsulo cha carbon pomwe kamakhala ndi magwiridwe antchito ofanana ndi chitsulo cha carbon. Chifukwa cha magwiridwe ake abwino, mtengo wotsika, chagwiritsidwa ntchito kwambiri padziko lonse lapansi. Komabe, chitsulochi chimakhala ndi chizolowezi chojambula zithunzi pambuyo pa ntchito yayitali kutentha kwambiri, kotero kutentha kwake kuyenera kulamulidwa pansi pa 510℃, ndipo kuchuluka kwa Al komwe kumawonjezeredwa mu kusungunula kuyenera kuchepetsedwa kuti kulamulire ndikuchedwetsa njira yojambula zithunzi. Chubu chachitsulo ichi chimagwiritsidwa ntchito makamaka pa superheater yotsika kutentha komanso reheater yotsika kutentha. Kutentha kwa khoma kuli pansi pa 510℃. Kapangidwe kake ka mankhwala C0.12-0.20, SI0.10-0.35, MN0.40-0.80, S≤0.035, P≤0.035, MO0.25-0.35; Mphamvu yachibadwa σs≥270-285, σb≥450-600 MPa; Plastiki delta 22 kapena kupitirira apo.
