Low Emissions Combustion System Development for the GE Energy High Hydrogen Turbine Program

Abstract

Progress on the joint GE Energy/US Department of Energy (DOE) High Hydrogen Turbine Program is presented. A summary of GE’s current integrated gasification combined cycle (IGCC) experience is provided. The Phase I approach is discussed with selected results included. The program follows the well-established GE approach to introducing new technology through: fundamental laboratory testing and analysis; subscale demonstration; full-scale development; full-scale verification. Advancements towards the ultimate goal of ultralow NOx emissions with coal derived pre-combustion carbon capture fuels are presented. Feasibility of diluent-free low NOx combustion is demonstrated experimentally at gas turbine conditions with representative fuel compositions. Phase II design challenges are highlighted within the framework of Phase I results.
