This paper presents the results of an evaluation of repowering a typical US based coal fired power plant with a combination of coal gasification and advanced turbine technologies. In this case, an oxygen blown, fixed bed gasifier (based on British Gas-Lurgi technology) generates clean, low temperature, medium Btu gas which is fired in an advanced type of power cycle; namely, the Cascaded Humidified Advanced Turbine, or CHAT cycle which is defined and described below. This conceptual site repowering follows the same methodology and uses the same design parameters as in a recent evaluation of plant repowering utilizing a broad suite of advanced technologies, many of which are currently being demonstrated in the Clean Coal Technology Demonstration Program.
