Carbon Sequestration
Capture Project Descriptions
Conceptual Design of Oxygen-Based PC Boiler
Project # 41736
Primary Performing Organization:
Foster Wheeler Development Corporation
The contribution of this project to improving carbon dioxide (CO2) capture technology is to develop a conceptual pulverized coal (PC) fired boiler system design using oxygen as the combustion medium. Using oxygen instead of air produces a flue gas with a high CO2 concentration, which will facilitate CO2 capture for subsequent sequestration.
Studies have indicated that, among other things, a higher flame temperature results in a more compact furnace and less gas recycle. It also leads to higher cycle efficiency due to greater boiler efficiency. See spatial comparison of an air-fired furnace with an oxygen-fired furnace.
This project contemplates a comprehensive literature review to evaluate previous work in this area. From that information process modeling simulations will be made. These simulations should lead to a conceptual design that addresses costs, performance, and emissions, and will conclude with a comparison to conventional systems. If all objectives are achieved, the project will result in a conceptual design of a process that is competitive with an integrated gasification combined-cycle (IGCC) system in terms of cost of electricity and CO2 mitigation cost when CO2 is being captured.
