【 摘 要 】

This is the sixth Quarterly Technical Report for DOE Cooperative Agreement No: DE-FC26-00NT41047. The goal of the project is to develop and demonstrate a computational workbench for simulating the performance of Vision 21 Power Plant Systems. Within the last quarter, good progress has been made on the development of our IGCC workbench. Preliminary CFD simulations for single stage and two stage ''generic'' gasifiers using firing conditions based on the Vision 21 reference configuration have been performed. Work is continuing on implementing an advanced slagging model into the CFD based gasifier model. An investigation into published gasification kinetics has highlighted a wide variance in predicted performance due to the choice of kinetic parameters. A plan has been outlined for developing the reactor models required to simulate the heat transfer and gas clean up equipment downstream of the gasifier. Three models that utilize the CCA software protocol have been integrated into a version of the IGCC workbench. Tests of a CCA implementation of our CFD code into the workbench demonstrated that the CCA CFD module can execute on a geographically remote PC (linked via the Internet) in a manner that is transparent to the user. Software tools to create ''walk-through'' visualizations of the flow field within a gasifier have been demonstrated.
