A335 P92(e pili ana i ka papa maʻamau Kina 10Cr9MoW2VNbBN) he kila martensitic kūpaʻa wela hanauna hou i hoʻomohala ʻia maiP91Ma ka hoʻohui ʻana i ka tungsten (W) i ka 9% chromium steel a me ka hoʻonui ʻana i ka molybdenum equivalent (Mo+0.5W) mai kahi o 1% ma P91 a i kahi o 1.5%, ua hoʻonui nui ʻia ka hana wela kiʻekiʻe o ka mea.

ʻO nā wahi noi mua:

Hana Mana Wera Ultra-supercritical: ʻO P92 ka mea nui no nā paipu mahu nui a me ka hoʻomehana hou ʻana i nā paipu mahu ma nā ʻāpana ultra-supercritical papa 1000MW, me ka mahana hana hoʻolālā kiʻekiʻe loa o 625°C. Ma 600°C, hiki i ke kaumaha i ʻae ʻia e ka hoʻolālā ke hōʻea i 128MPa, a me ka ikaika kolo wela kiʻekiʻe≥100MPa. ʻO kona ikaika haki kolo wela kiʻekiʻe ma kahi o 30% ʻoi aku ka kiʻekiʻe ma mua o P91, me kahi ʻāpana miliona-kilowatt hoʻokahi e hoʻopau ana a hiki i 800 tons.

Nā ʻĀpana Koʻikoʻi o ka Boiler: Hoʻohana nui ʻia i nā poʻomanaʻo paila, nā superheaters, nā reheaters, a me nā ʻāpana kaomi ʻē aʻe. ʻO ia kekahi o nā papa kila i makemake ʻia no ka hana ʻana i nā lako hana mana wela nui ma ka home a ma ka honua holoʻokoʻa.

ʻOihana Petrochemical: Hoʻohana ʻia i nā paipu reactor hydrogenation, nā ʻōmole umu e haki ana, a me nā ʻōnaehana wela a me ke kaomi kiʻekiʻe.

Mana Nukelea: Hoʻohana pū ʻia i nā ʻōnaehana paipu ʻaoʻao lua o nā mea kanu mana nukelea o ke kolu o ka hanauna e like me AP1000.

Ke hoʻohālikelike ʻia me nā kila kila austenitic, hāʻawi ʻo P92 i nā pono e komo pū ana me ke kūpaʻa ikaika i ka pala, ka conductivity thermal kiʻekiʻe, a me ka coefficient hoʻonui thermal haʻahaʻa.

II. Nā Hale Wili Kila Kūloko me nā Pōmaikaʻi Hoʻokūkū

He mea paʻakikī ka hoʻomohala ʻana o ke kila P92, e koi ana i nā kūlana kiʻekiʻe loa i ka hoʻolālā kaʻina hana a me ka kaohi hana. I kēia manawa, he palena wale nō ka nui o nā hale wili kila kūloko i loaʻa ka mana hana paʻa.

1. Pūʻulu Beizhong—Alakaʻi Māhele Mākeke

Loaʻa iā Beizhong Group ma mua o 80% o ka māhele mākeke ma ka ʻāpana paipu kila P92 kūloko. Ua hala kāna huahana i 28 mau hōʻailona nānā, a ua lanakila kāna mau hoʻokō ʻenehana i ka makana mua o ka China Electric Power Science and Technology Innovation. Ua hoʻokō ka hui i ka uhi piha maiΦ89 a iΦ813, me nā moʻolelo hana ʻenekinia nui i ka hoʻolako ʻana i ʻehā mau paipu nui no nā ʻāpana ultra-supercritical.

2. Hui Yonggang—Nā Pōmaikaʻi i ka Hana ʻana o Billet

Ua hoʻāʻo pono ʻo Yonggang Group i ka hana ʻana iā SA335 P92 i ka makahiki 2017 a i kēia manawa ua loaʻa iā ia ka mana e hana i nā billets poepoe hoʻolei mau i nā kikoʻī maiφ380mm a iφ800mm, e hāʻawi ana iā ia i kahi lihi hoʻokūkū ma ka mākeke billet nui kūloko. ʻO ka P91, P92, a me nā huahana billet poepoe nui ʻē aʻe o ka hui e paʻa ana i kahi kūlana mākeke alakaʻi ma Kina. Eia kekahi, ua koho ʻia ʻo ia ma ke ʻano he hale hana hōʻikeʻike hana akamai pae aupuni, e hoʻomaikaʻi mau ana i ka kaohi maikaʻi o ka huahana a me ka hoʻonui ʻana i ke kumukūʻai.

3. Nā Lako Hana Nukelea ʻo Hebei Hongrun—Nā Lako Hana a me ke Kaʻina Hana Kūikawā

Hoʻohana ʻo Hongrun Nuclear Equipment i kahi mīkini paʻi extrusion kū pololei he 50,000-tona e hana i nā paipu kila humuhumu P92 nui. Ma ka laulima ʻana me Baowu Special Steel, hoʻohana ia i nā ʻoaka kila kiʻekiʻe, e hopena ana i nā huahana me ke ʻano paʻa a me ka hana maikaʻi loa. Ua hala kāna mau paipu kila P92 i ka palapala hōʻoia huahana e ka National Power Equipment Center, me nā ʻōkuhi hana āpau e hoʻokō ana i nā koi maʻamau GB/T 5310 a me ASME SA335.

4. Nā Mea Hana ʻē aʻe

Ua hoʻokō ʻo Baosteel Special Steel, Tianguan Group, Xinxing Ductile Iron, a me nā ʻoihana ʻē aʻe i ka hōʻoia hana nui o nā huahana e pili ana iā P92, e paipai ana i ke kaʻina hana localization o kēia mea.

III. Nā Pōmaikaʻi Hoʻokūkū Holoʻokoʻa

ʻO nā pono hoʻokūkū o nā hale wili kila kūloko ma nā huahana P92 e hōʻike nui ʻia ana i: ka mua, ua hoʻemi nui ʻia nā kumukūʻai kūʻai ma o ka hoʻololi ʻana i nā mea lawe mai; ʻo ka lua, ua hoʻomaikaʻi ʻia ke kūpaʻa o ka maikaʻi o ka huahana i hoʻokele ʻia e ka hoʻololi akamai a me ka kikohoʻe (e laʻa, ua hoʻokō ka papahana hale hana akamai o Yonggang i ka piʻi ʻana o ka pono hana ma mua o 12% a me ka hoʻemi ʻana o ka helu kīnā he 15.7%); a ʻo ke kolu, nā holomua mau i nā kikoʻī kiʻekiʻe e like me nā paipu nui a me nā paia mānoanoa, e hoʻemi mālie ana i ka hilinaʻi ʻana i nā mea lawe mai.
