Role in CHEERS
WP 3 – Oxygen carriers and characterisation of fuel conversion phenomena
As we know, CO2 is the primary greenhouse gas causing global warming which has aroused increasing attention all over the world. Fossil fuels used for power generation account for a large amount of CO2 emission. It is a great challenge to separate, capture and store CO2 from power generation. Chemical looping combustion is a new and novel technology with characteristic of inherent separation of CO2 without energy penalty. The use of coal in CLC is very attractive in future with restriction in CO2 emissions, since coal will keep on being a main energy source in the medium term. Better understanding of the characteristic of chemical looping combustion system, especially for micro scale, is the basement of industrial application. The computational fluid dynamics method has become a well-developed academic discipline and an effective instrument for engineering problems, which will play a significant role in the CHEERS project.
Zhejiang University will carry out the numerical study on the characteristic of chemical looping combustion system in CHEERS project. Fully-resolved simulation of char particle conversion will be considered and execute firstly. A ghost-cell immersed boundary method will be developed and implemented to investigate the heat and mass transfer during combustion. Also, the Eulerian-Eulerian/Eulerian- Lagrangian method will be used to research behavior of the reactor.
Objectives:
- To provide detail information of fuel particles combustion in micro scale by fully-
resolved simulation - To promote the accuracy of model used for chemical looping combustion
- To investigate the flow behavior, heat and mass transfer, and reaction characteristics
of the system
