The research project of "Technology for MGC (Melt-Growth Composite) ultra high-efficiency gas-turbine system" has been started since 2001. MGC material is known to show high strength unchanged at the temperature as high as 1700℃. It is considered that NOx emissions must increase in the temperature condition, to which MGC will be applied. Therefore, research of a unique low NOx combustor, with which the increase of NOx formation can be suppressed drastically, has been carried out. The key techniques are a rapid mixing & combustion technique, a staged combustion technique, and a technique to apply MGC to combustor liners. This paper describes the outline of the research activities.
