Advanced Ultra Super Critical (A-USC)

Coal-fired thermal power

USC maximum efficiency: about 42% (transmission end HHV)

Main steam pressure: 25Mpa

Main steam temperature / reheat steam temperature: 600/600℃

A-USC efficiency: a further 10% improvement

Main steam pressure: 35Mpa

Main steam temperature / reheat steam temperature: 700/720/720℃

Further efficiency improvements with steam in excess of 700 degC


We developed a Ni base material that can withstand high temperature steam,

and manufactured rotor, casing and turbine blade.
