Show the ability to control their individual operation, and optimization of a complete overfrre air system must be demonstrated in Phase IV. Previous work in Phase II employing the S MBtulhr and 100 MBtulhr burners as well as modeling of the POC facility will provide the performance characteristic link between the POC and the CGU. CONCLUSIONS With pilot -scale testing completed and the design of the Subsystem Test and POC Demonstration Facilities in progress, B&W's view of what it will take to provide a commercial generating unit which will meet the LEBS program goals is coming into clearer focus. A combination of further study and the results of pilot and subsystem scale testing is narrowing the alternatives and improving the system designs initiated in the preliminary Phase I work. With the completion of Subsystem Testing, B&W expects to further confmn and refine the LEBS design and costs in preparation for Proof-of-Concept Demonstration in Phase IV. Upon completion of the LEBS program, B&W anticipates having a commercial product capable of successfully competing with the other emerging advanced coal-fired technologies in both performance and cost.
