Testing of the 50 MW(T) Coal-Fired MHD Combustor First Stage at the DOE Component Development and Integration Facility

摘要

Testing of the first stage of the 50 MW/sub t/ MHD Coal-Fired Combustor (CFC) was successfully completed at the CDIF on schedule between September 20, 1984 and January 30, 1985. The objective of the first stage CFC testing, i.e., to characterize CFC operating ranges and to verify operation of the first stage CFC with all related facilities at the CDIF, were all achieved during this testing period. CDIF facility/CFC compatibility was verified through various facility tests, cold flow functional tests, hot flow tests and early vitiator/coal ignition checks. Process flow, flow control, structural support, instrumentation, and the data acquisition system were tailored specifically to the CFC during a major site modification prior to CFC installation. The facility, support systems and operational capabilities satisfactorily supported the testing program and developed the quality data base for the CFC characterization testing. During the testing the data analysis capabilities were enhanced when the ability to provide ''real time'' data transmission to TRW's offices in California was developed and used by TRW staff to monitor the ongoing tests. Test results obtained during the performance characterization testing indicate that the performance criteria for CFC first stage heat loss, heat flux, operational stability, slag retention, and slag recovery were satisfied. The testing program encompassed a sufficiently wide range of conditions to identify an operating envelope for optimum combustor performance for the upcoming testing of the MHD power train. 18 figs., 13 tabs.
