Study on the highly efficient closed-cycle turbine system for CO{sub}2 collection

摘要

In WE-NET project Phase I Program, the power generation system with more than 60% (HHV) thermal efficiency had been designed. However, because this system must be fueled by pure hydrogen, commercialization of this system in early stage is thought to be difficult. Therefore, the new project, in which the natural gas fueled system is targeted, has been started since FY 1999. In this project, the power generation efficiency is aimed to be 60% (HHV) or higher, with turbine inlet maximum temperature of 1973 K. In this report, effects of some parameters are evaluated and the main components are conceptually designed.
