Abstract: While the water vapor content of the combustion gas in natural gasfired landbased turbines is ∼10%, it can be 20–85% with coalderived (syngas or H2) fuels or innovative turbine concepts for more efficient carbon capture. ...

Abstract: Several factors are being investigated that affect the performance of thermal barrier coatings (TBC) for use in land-based gas turbines where coatings are mainly thermally sprayed. This study examined high velocity oxygen ...

Abstract: Hydrogen-fueled microturbines are being considered as part of the future green microgrid. However, the use of hydrogen as a fuel presents new challenges for selection and development of suitable high temperature materials ...

Abstract: Air plasma sprayed (APS) flash coatings on high velocity oxygen fuel (HVOF) bond coatings are well known to extend the lifetime of thermal barrier coatings (TBCs). Recent work compared flash coatings of NiCoCrAlY and ...

Abstract: Direct-fired supercritical CO2 (sCO2) power cycles are a pathway to low-CO2 fossil energy but contain O2 and H2O in the sCO2 from combustion. The effect of impurities on structural steels was investigated at 450°–650 °C ...

Abstract: Aluminaforming austenitic (AFA) steels represent a new class of corrosionand creepresistant austenitic steels designed to enable higher temperature recuperators. Field trials are in progress for commercially rolled foil ...
