Paper Title:
Materials Technology for PC-TPP in Green Economic Era
  Abstract

Coal fired power generation should be amalgamated with efficiency improvement technology of electric-power production and treatment technology of greenhouse gas in green economic era. The efficiency of fossil power plant can be achieved by increment of temperature and pressure of steam, and the performance improvement of the components. The improvement of temperature and pressure of live steam can be supported by the materials with high temperature strength and the excellent resistance to oxidation. Specially, verified materials have to be used in large quantities for both repair and replacement of steam facing components. The efficiency of newly constructed Pulverized Coal – Thermal Power Plant[PC-TPP] is higher than 42% at Ultra Super Critical[USC] conditions of 250~300 bar and 600~610oC. Recently, material technology has been developed to build PC-TPP of the steam condition of advanced USC with more than 46% efficiency. However, it is expected to have problems to economically manufacture in large quantities. Therefore, the paper explains the current the state of the art of materials technologies and the issues with the steam.
