Advanced Experimental Technologies for Gas Turbine Engines Suited to the Commercial Power Generation Systems

Abstract

The role of GTCC systems in power grids as the means of absorbing the electric power fluctuations is growing in importance as the introduction of wind and solar power is being promoted. The development of large industrial gas turbines primarily focuses on raising the turbine inlet temperature (combustion temperature) for higher efficiencies. Various underlying technologies are employed to suppress the increase in NOx emissions and combustion oscillations due to higher temperatures. This special article introduces the combustion measurement technologies used for gas turbine combustor development, such as Planar Laser-Induced Fluorescence (PLIF), Computed Tomography (CT) of chemiluminescence, and Tunable Diode Laser Absorption Spectroscopy (TDLAS).
