Status of advanced ultra-supercritical pulverised coal technology (CCC/229)

In pulverised coal combustion (PCC) power plant, increasing the maximum temperature of the steam cycle increases the electrical efficiency, which in turn lowers both coal consumption and flue gas emissions. However, the maximum steam temperature is limited by materials that can operate at these conditions for practical service lifetimes without failure. The EU, USA, Japan, India and China all have material research programmes aiming for the next generation of increased steam temperatures and efficiency, known as advanced ultra-supercritical (AUSC) or 700°C technology. This report reviews  developments and status of these major material research programmes.
