Advanced Combustion Turbines

R&D in Advanced Combustion Turbines is focused on components and combustion systems for advanced combustion turbines in combined cycle operation that can achieve greater than 65% combined cycle efficiency (LHV, natural gas benchmark) and support load following capabilities to meet the demand of a modern grid. To achieve this target, emphasis will be placed on advanced turbine concepts that are fueled with natural gas and coal derived fuels, including hydrogen and syngas, and higher firing temperatures (3,100°F).

Component R&D is being conducted that will allow higher turbine inlet temperatures, manage cooling requirements, minimize leakage, advance compressor and expander aerodynamics, advance the performance of high temperature load following combustion systems with low emissions of criteria pollutants including oxides of nitrogen (NOx), and overall lead to improved efficiency of the gas turbine machine in a combined cycle application. Projects in this topic area include research on ceramic matrix composite components and advanced turbine configurations for improved cooling and efficiency.
