Status of proof-of-concept testing at the CFFF (Coal Fired Flow Facility)

This paper will summarize the results of POC testing at the DOE CFF during CY 1989. At the end of this period, more than 1500 hours of testing had been completed. Major efforts for the period included continued evaluation of the baghouse (BH) and Electrostatic Precipitator (ESP) in removing particulate under parametrically varied conditions. Results of the redesigned superheater test module (SHTM), which provides more flexibility to meet desired test temperatures, increased the number of sootblowers and increased tube spacing will be covered. The status of facility modifications will be detailed. This includes the provision of a high pressure air system for sootblowing tubes with molten tube deposits, installation of an automated ash/seed handling system and the engineering investigations into modification of the coal processing system to handle western coal. The latter capability is needed in FY-91 for the beginning of the scheduled 2000 hours Proof-of-Concept (POC) testing with western coal. Performance of test components and improvements made during the year will be summarized. Plans for the balance of FY-90 and the remaining years in the POC program will be presented. 2 refs., 17 figs., 3 tabs.
