Gas Turbine Technology for Steel Mill Gas and Syngas Applications

Abstract

Recent market place activity over the past years has shown a renewed trend in using steel mill waste gas for combustion in gas turbines. To effectively use steel mill gas, as well as other industrial off gases and syngas from gasification, more than just the combustion process has to be considered. With steel mill gases some of the more critical areas involve gas clean up and compression, as well as integration with the steam system of the host industrial plant. This paper will summarize some of the special considerations for applying a gas turbine/combined cycle power plant to a steel mill. Due to the similarities of the fuels, this paper will also discuss how this is common to other industrial gases applications. GE has substantial experience in combustion of low calorific fuels as well as industrial process gases and more recently steel mill gases.
