Title: Feasibility Study of an Integrated Coal Gasification Combined Cycle System with Oxygen-Blown Gasifier.
Abstract: This paper describes the results of feasibility study on an Integrated Coal Gasification Combined Cycle (IGCC) Power Plant of 350 MW unit output. The purpose of this study is to achieve higher thermal efficiency by composing the proven and high reliable components. The selected IGCC process in this study consists of a coal dry feed oxygen-blown pressurized entrained flow gasifier, a wet low temperature cleanup system, a high temperature gas turbine, a reheat steam cycle and a cryogenic air separation unit. In this study, steam cycle conditions and performances of main components based on the latest technologies are surveyed and evaluated, furthermore this study also evaluates the highly integrated system which integrates an air separation unit and a gas turbine. As a result of this study, more than 43% (HHV) net efficiency is expected.
