超臨界CO₂サイクル火力発電用ガスタービン

抄録

Carbon dioxide (CO₂) emission from thermal power plants is one of the primary causes of global warming. Demand has therefore been increasing for innovative technologies to reduce CO₂ emission. To meet this demand, Toshiba has been engaged in the development of a CO₂ turbine and combustor applying a supercritical CO₂ cycle fossil power system that separates and collects CO₂ without the need for any carbon capture system. The combustor of the new system burns a mixture of fossil fuel and oxygen combined with CO₂ to produce a working fluid, mainly consisting of high-temperature and high-pressure CO₂ and water vapor, which is used to drive the CO₂ turbine generator.
