Combined Air and Steam Cooling of Large Frame Gas Turbines - Design, Features, Cooling Concept and Experience

摘要

The first commercial steam-cooled gas turbine was commissioned ten years ago in Takasago, Japan. Today, Mitsubishi's fleet has grown to 20 units accumulating more than 440,000 actual operating hours as of March 2007. The high reliability and availability numbers reported have cleared the concerns associated with the technology and silenced sceptics. This is reflected in orders exceeding 36 new units that are currently in commissioning, installation or manufacturing for plants in Europe, USA and Asia.
