OSTI ID:5981667

The subject of this report identifies progress for Phase I -- Design and Permitting and Phase IIA -- Long Lead-Time Item Procurement. Under Phase I, the following activities are discussed. Task 1 -- Management and Reporting included completing the Project Work Plan, the Project Evaluation Plan, and the Environmental Monitoring Plan. Under Task 2 -- Pilot-Scale Cyclone Boiler Tests, reporting the results from the second coal tested, a high sulfur Illinois coal, is summarized in this document. These data, both baseline and reburning results, will broaden the technological basis for commercialization of the technology. Activities in Task 3 -- Numerical and Physical Flow Modeling concentrated on completing their subtasks in order to provide reburn system design recommendations. Discussions pertaining to the modeling methodology is included in this report. The Baseline Characterization Test Report -- Task 4 continues in the preparation stage due to the concentrated effort in the reburn system design phase. For Task 5 -- Design of the Reburn System, general arrangement drawings were completed in order to allow detailed activities to commence. The reburn burner/OFA port designs are nearing completion and should be finalized within the next quarterly report. Finally, Task 6 -- Permitting Activities continue. The major components of this document include the results of the high sulfur coal pilot scale tests, the numerical/physical flow modeling recommendations, additional Nelson Dewey No. 2 baseline test data, and a summary of the overall reburn system design. The reburn system design involves input from all the project's tasks and thus, this document assembles a summary of the tasks performed to date with the culmination being the proposed reburn system design. 14 figs., 4 tabs.
