Isbeddellada horumarinta ee birta kuleylka u adkeysata
Fiiro gaar ah:
Marka loo eego dhaqanka caalamiga ah, waxa loogu yeero pearlite, bainite, iyo birta kuleylka u adkeysata ee martensitic ee kuleyliyaha iyo birta tuubooyinka waxaa si wada jir ah loogu yeeraa "birta kuleylka u adkeysata".
Iyada oo la hagaajinayo qaab dhismeedka tamarta dalkayga iyo hagaajinta dhismaha tamarta, waxtarka sare, nadiifka ah, iyo deegaanka u wanaagsan cutubyada awoodda weyn iyo kuwa cabbirkoodu sarreeyo ayaa noqday kuwa ugu sarreeya.Iyadoo la kordhinayo cabbirada uumiga (cadaadiska iyo heerkulka), waxay si wax ku ool ah u wanaajin kartaa waxtarka kulaylka ee unugga, waxay yaraynaysaa isticmaalka dhuxusha, waxayna yaraynaysaa qiiqa CO2.Waqtigan xaadirka ah, habka ugu muhiimsan ee lagu wanaajin karo waxtarka unugyada tamarta kulaylka waa in la hagaajiyo cabbirrada uumiga iyo horumarinta unugyada supercritical (SC) iyo ultra-supercritical (USC).Waqtigan xaadirka ah, waxaa jira in ka badan 100 milyan-kilowatt unugyo ultra-supercritical (USC) oo laga hirgeliyay dalkayga, oo kaalinta koowaad kaga jira adduunka tiro ahaan iyo wadarta labadaba.
