The subject of this report identifies progress during the quarter for Phase 1 - Design and Permitting. Under Task 1 - Management and Reporting, the Project Work Plan, the Evaluation Plan, and the Environmental Monitoring Plan outline were initiated. Activities in Task 2 - Review of Reburning Technology and Pilot-Scale Cyclone Boiler Tests, concentrated on completing the pilot-scale baseline/reburning tests in order to provide a data base for the reburn system design at Nelson Dewey. Under Task 3 - Numerical and Physical Flow Modeling, work was initiated to verify the models baseline furnace gas flow patterns in order to allow utilization of these models in the reburn system design considerations. Completion of the Nelson Dewey Unit {number sign}2 baseline tests occurred in order to satisfy Task 4 - Baseline Characterization Tests. These tests are integral for not only evaluating the future effects after the reburn retrofit, but in addition will help aid in the reburn system design. For Task 5 - Design of the Reburn System, preliminary general arrangement drawings were started to identify potential equipment locations and flue/duct/pipe routings. Finally, Task 6 - Permitting, was initiated. The major components of this document deals with the results of the pilot-scale baseline and reburning tests. These data identify the potential positive/negative aspects of the coal reburning technology. Thus, the pilot results will certainly enhance the background experience basis for the overall reburn system design. In addition, this report highlights the baseline tests which were performed at Nelson Dewey Unit {number sign}2. 7 figs., 2 tabs.
