概要

Power generation with supercritical CO_2 closed cycle gas turbine was successfully demonstrated using a bench scale test facility. 60 minutes self-sustaining operation including 40 minutes of continuous power generation was realized. Compressor work reduction depending on decrease in compressibility coefficient at the compressor inlet was experimentally confirmed. The typical continuous power output was 200W, which was much smaller than the designed specification of the test plant. The main reason of small generated power was estimated to be low adiabatic efficiency of the turbo machineries, windage around the generator rotor, leakage flow from the compressor outlet to the turbine inlet through the inside of generator.
