Project Description

Under the American Recovery and Reinvestment Act (ARRA) funded program, Siemens Energy will focus on advancing state-of-the-art large natural gas fired turbine technology to produce turbines specifically designed for operation on hydrogen and syngas fuels derived from industrial processes that capture a large percentage of CO2. Advanced technologies and concepts will be evaluated, down selected, and validated. The advanced technologies, component designs, and manufacturing processes will be developed and verified in sub-scale and full-scale tests and process verifications to demonstrate that the program goals can be achieved. Some of the key enabling technologies needed are as follows: Fuel-flexible, ultra low NOx, long-life combustion system operating at the increased firing temperatures needed to achieve high efficiency. Siemens will work to develop a premixed combustion system capable of operating on hydrogen fuel at high temperatures with minimal dilution flow. As part of this development, modeling tools for thermal acoustics and computational fluid dynamics will be adapted for hydrogen fuels and validated with test data. The primary path for the hydrogen combustor is a modification of the current Siemens premixed natural gas burner to operate on hydrogen. In addition, as risk mitigation, several alternative combustion technologies will be evaluated to determine if they can provide an improvement for high-temperature hydrogen operation.

Development and optimization of higher temperature material system (base alloy, bond coat, and thermal barrier coatings [TBCs]) capabilities that allow operation in challenging environments, thus ensuring that the turbine components achieve high reliability and long life.

Advanced manufacturing processes and techniques essential to producing the novel turbine cooling schemes that are being pursued in this program. Siemens will be producing full-sized engine parts using advanced core making technology, performing investment casting trials, conducting destructive and non-destructive evaluations, machining prototype parts using a proposed production process and conducting full-scale engine testing on final products.

New sensors and diagnostics to allow more efficient, fuel-flexible, and safe gas turbine operation. Customer interviews determined key sensing needs and sensor specifications for these needs. Based on these results, Siemens will work with sensor vendors to design, develop, and validate sensor designs for engine validation or use in on-line control.

Project Benefits

This project will focus on advancing state-of-the-art industrial-frame turbine technology for hydrogen fueled turbine machinery. Advanced turbine components will improve the efficiency, performance, and emissions of IGCC systems. Specifically, this project will construct and test advanced turbine components including hydrogen combustion components, materials, sensors, and airfoil designs under load conditions.
