Advanced Oxy-Combustion Technology Develop and Scale-Up for New and Existing Coal-Fired Power Plants


Performer: Washington University in St. Louis

Project No: FE0009702


Project Scope and Technology Readiness Level


The Phase II research team comprises Washington University in St. Louis and EPRI, with assistance from Praxair and Ameren. The primary tasks include design and construction of a laboratory-scale pressurized combustor and experiments to measure heat flux, temperatures, concentrations of gases and ash, and ash deposition rates. The recipient team will analyze the data to better understand the staged, high-pressure oxy-combustion (SPOC) process and validate the computational fluid dynamics (CFD) models that were relied upon in Phase I. The team will rerun the simulations based on the results of the analysis to ensure optimal boiler design. Corrosion studies will also be conducted to evaluate the corrosion characteristics of common and advanced boiler tube materials when they are subjected to the environments anticipated in the SPOC process as determined by the experiments. The recipient will improve the process modeling—including in the key area of the direct contact cooler—and update the Phase I techno-economic models to reflect the new information.

The Technology Readiness Level (TRL) assessment identifies the current state of readiness of the key technologies being developed under the DOE’s Clean Coal Research Program. This project has not yet been assessed.

The TRL assessment process and its results including definition and description of the levels may be found in the "2012 Technology Readiness Assessment-Analysis of Active Research Portfolio".
