Since 1997, five Japanese gas turbine makers have been developing a low-NOx, high-efficiency, next-generation, marine gas turbine (Super Marine Gas Turbine, or SMGT). The target goals for this 2,500 kW class marine gas turbine include NOx emissions of less than 1g/kWh, a thermal efficiency of 38 to 40 %, and the ability to use fuel oil type A. The SMGT is being developed primarily as a main engine for coastal shipping vessels. The 6-year R&D plan calls for performance evaluation of a 2,500 kW class prototype gas turbine in the plan's final year. At present, research is underway on the following main components: the combustor, recuperator, compressors and turbines. To achieve the above goals, the following are being developed: a DLN combustor that can burn liquid fuel (fuel oil type A), a regenerative cycle using a plate-fin recuperator, a compound high-efficiency axial + radial compressor, and a high-efficiency cooled blades. This paper outlines the current state of this research.
