Fuafuaga atia'e o u'amea fa'afefe vevela
Fa'aaliga:
E tusa ai ma faiga faʻavaomalo, o le mea e taʻua o pearlite, bainite, ma martensitic uʻamea faʻafefe vevela i totonu o pusa ma paipa ua taʻua faʻatasi o "ferritic heat-resistant steels".
Faatasi ai ma le fetuunaiga o le fausaga o le malosi o loʻu atunuu ma le faʻaleleia atili o le fausiaina o le eletise, maualuga-lelei, mama, ma faʻafeiloaʻi le siʻosiʻomaga tele-mafai ma maualuga-parameter iunite ua avea ma pule. E ala i le faʻateleina o faʻamaufaʻailoga ausa (omiga ma le vevela), e mafai ona faʻaleleia lelei le faʻaogaina o le vevela o le iunite, faʻaitiitia le faʻaaogaina o le koale, ma faʻaitiitia le faʻaaogaina o le CO2. I le taimi nei, o le auala autu e faʻaleleia ai le faʻaogaina o iunite eletise vevela o le faʻaleleia lea o faʻamaufaʻailoga vaʻa ma atiina ae supercritical (SC) ma ultra-supercritical (USC) iunite. I le taimi nei, e sili atu i le 100 miliona-kilowatt ultra-supercritical (USC) iunite o loʻo faʻaogaina i loʻu atunuu, tulaga muamua i le lalolagi i le aofaʻi ma le aofaʻi atoa.
