In this quarterly technical progress report, UTSI reports on the results of a multi-task contract to develop the technology need for a steam bottoming plant for a combined cycle MHD steam power plant. The primary emphasis is on proof-of-concept (POC) testing of the steam bottoming plant components. During this quarter, a 252 hour test was completed with Eastern coal which completes 1760 hours of the planned 2000 hours of testing with this coal. The performance of the baghouse and electrostatic precipitator (ESP) during the test is summarized. The baghouse met new source performance standards (NSPS) for particulate emission. The ESP performance was improved over recent past tests and its performance was mapped as a function of specific collection area (SCA) and plate rapping frequency. The results of analysis of tube materials after the first 500 hours of exposure is noted as being separately published as a topical report. Representative results of deposition on heat transfer tubes during the test are presented along with heat transfer coefficients of the dirty tubes. The results of advanced instrumentation experiments by both UTSI and Mississippi State University (MSU) are summarized. Measurements of pollutants dispersed from the CFFF stack to remote air quality monitoring trailers are presented. Test results on a ceramic tube that is a candidate for high temperature air heater service are included. The test of a prototype of the first stage of the TRW 20 MW{sub t} combustor was successfully carried out in the combustor during the POC test this quarter. It was installed with adapter flanges to the 20 MW{sub t} single stage combustor used in the CFFF. A report of the performance of this test article is appended to the report. 2 refs., 24 figs., 8 tabs.
