The coal reburning for cyclone boiler NO{sub x} control demonstration project's 3rd Quarterly Report covering the time period of October, November, and December 1990 involves the work performed in Phase 1 -- Design and Permitting and Long Lead-Time Procurement. Phase 1 activities focused on finalizing each of the following tasks: management and reporting; review of reburn technology and pilot scale cyclone tests; numerical physical flow modeling; baseline characterization; design of reburning system; permitting. Specifically, the Project Evaluation Report for Phases 1 and 2A and the Continuation Application for Phase 2B were submitted to DOE/PETC for approval. The general arrangement drawings of the reburning system continued to be updated and revised. Work involving the preliminary final report for the numerical/physical flow modeling evaluation was initiated. Installation of the foundation for the pulverizer enclosure was begun. Finally, Phase 2A -- Long Lead-Time Item Procurement activities included purchasing the primary air fan and motor, the gravimetric feeder, the boiler data acquisition system, the pulverizer gear drive and motor, and materials to fabricate the pulverizer.
