Testing, Evaluation, and Validation of Detailed Mechanistic Codes for Fluidized Bed Gasifiers. Final Report

摘要

To support its experimental fluidized bed coal gasification program, DOE has sponsored the development of detailed mathematical models of gasification reactors. The purpose of these models is to provide insight into the process occurring with the reactors and to investigate the effects of reactor design on the performance of the fluidized bed. Successfully achieving these objectives would provide the capability to investigate the scale-up of pilot plant reactors and to optimize the coal gasification process through parametric studies. Two of these models are embodied in the computer codes CHEMFLUB and FLAG. The BDM Corporation was retained by the Morgantown Energy Technology Center of DOE to verify, evaluate, and document the CHEMFLUB and FLAG codes. This report consists of a description of BDM's experience with the FLAG and CHEMFLUB codes. Chapter 2 describes the results for CHEMFLUB and Chapter 3 describes the results for FLAG. The results of the test case runs were reported in detail via the monthly reports. We have reiterated this data here in the final report. For the sake of clarity and reading convenience, lengthy tables have been postponed to appendices. Since each code responded differently to the initial test cases, each code was tested in a slightly different manner. Test cases were performed which were appropriate to the apparent difficulty manifested by each code. (ERA citation 10:008117)
