Description

The project is on schedule and under budget. The current status is shown in the Milestone Schedule Report included as Appendix A. All Project Plans were updated based on the revised finding level authorized for FY95 and anticipated for FY96. Technology Transfer activities included {open_quotes}supplying{close_quotes} three executives and several team members to the LEBS Workshop, delivering a technical paper at a conference, and working on a Combustion 2000 Session for another conference. ABBES and CeraMem reached agreement concerning Task 7 work, including ownership and disposition of project-purchased equipment to be used during Task 7 and also during Task 11. A test plan was prepared. Task 7 activities for the Low-NO{sub x} Firing System included computational modeling of the firing arrangement. Reasonable comparisons to experimental data previously obtained in the Boiler Simulation Facility were achieved. A kinetic evaluation for both baseline and low NO{sub x} firing arrangements was also performed, with results indicating that the final reducing zone within the main windbox has a dominant effect on NO{sub x} reduction, with higher temperatures being more favorable for lower NO{sub x}. A week of combustion testing was completed in the Fundamental Scale Burner Facility to examine the impact of integrated fuel staging (NO{sub x} reduction via the reburn mechanism), and to explore preliminary vertical staging concepts within the main windbox region. Preliminary results from this testing demonstrated the potential of vertical air staging within the main windbox to augment overfire air. Testing was performed to quantify the coal size distribution and power requirements for one (1) conventional static and four (4) dynamic classifier designs. Results from this testing show the dynamic classifier capable of producing finer grinds of coal at lower relative power requirements.
