This is the sixth quarterly report for this project and it covers work performed on Phase 3a of the project from February 1, 1992 through April 30, 1992. Extension of the parametric test period through June 1992 provides an opportunity to regain most of the schedule slippage, but only if the modifications needed for continuous operation of the CZD system are installed concurrent with the extended test period. These modifications include automation of the lime preparation and transfer system, automatic injection control, and related instrumentation and controls as necessary to integrate the operation of the CZD system with Seward Station Boiler No. 15. Early installation of these modifications would permit testing, debugging and adjustment of the automatic control system during the parametric test period. Results of current testing indicate that considerable testing and adjustment will be required to optimize operation of the CZD system after it is automated for continuous operation. Therefore, we intend to incorporate in Phase 3a(parametric testing) the system modifications needed for continuous automatic operation that were originally included in Phase 3b. Phase 3b would then be limited only to the one-year continuous demonstration.
