STUDIES ON CARBON DIOXIDE POWER PLANT.

Condensation cycles for power generation using carbon dioxide as a working fluid have higher efficiency than conventional steam cycles at a turbine inlet temperature higher than 650 degree C. Also, turbines can be constructed compactly owing to a small specific volume of carbon dioxide at the operating pressure, and the arrangements of the plant are simple as compared with those of the conventional steam cycles. Therefore they are suitable for large capacity steam and nuclear power stations. A power-generating plant of liquid phase compression, supercritical pressure cycle using carbon dioxide as the medium was designed and manufactured as an experimental apparatus of small scale, which comprises a pump, a regenerator, a heater, a turbine and condensers. In this report the experimental results of the static characteristics of respective components are described to obtain the basic data for practical plants.
