A team comprising Southwest Research Institute® (SwRI®), ITEA S.p.A., Jacobs, Electric Power Research Institute (EPRI), General Electric Global Research, and Peter Reineck Associates will design a transformational pressurized oxy-combustion facility. This project will provide preliminary, detailed design, specification, cost, and schedule metrics for a 10 MWe-scale combustion pilot plant to validate the performance of the Flameless Pressurized Oxy-combustion (FPO) technology for a broad range of coals on a large pilot scale (50 MWth). The project will bridge key technology gaps, and provide a clear understanding of scale-up rules required to engineer a commercial-scale, 500 MWe unit. The goal is to reach a Technology Readiness Level (TRL) of 7 with the 50 MWth pilot, which is a prototype that addresses scale-up issues prior to the commissioning of a commercial-scale demonstration plant. Key technologies that require demonstration at the 50-MWth scale are: the wet-grinding slurry feed, the combustor, the pressurized once-through steam generator (OTSG), the tempering mixer, and the turbo-expander. The planning of the 10 MWe plant will develop a roadmap to address these issues. The project will also provide a detailed Techno-Economic Assessment (TEA) report on the path to commercialization of the FPO technology.
