In this quarterly technical progress report, UTSI reports on progress on a multi-task contract to develop the technology for the steam bottoming plant for an MHD Steam Combined Cycle power plant. Two proof-of-concept (POC) tests totaling 614 hours of coal fired operation were conducted during the quarter using low sulfur Montana Rosebud coal. The results of these tests are summarized. Operational aspects of the particulate control devices being evaluated, a dry electrostatic precipitator (ESP) and a reverse air baghouse, are discussed. A sootblowing control system for the convective heat transfer surfaces that senses the need to clean the tubes by temperatures is described. Environmental reporting includes measurement of levels of ground water wells over time and the remote air quality measurements of impact of the stack emissions from the two tests. Results of testing candidate ceramic tubes for a recuperative high temperature air heater are included. Analyses of the tube materials tested in the 2000 hour test series previously completed on high sulfur Illinois No. 6 coal are summarized. Facility maintenance and repair activities for the DOE Coal Fired Flow Facility are summarized. The major facility modification discussed is the completion of the installation of a Wet ESP with rotary vacuum filter which is replacing the venturi scrubber as the primary facility particulate control device for any exhaust gases that are not routed through the dry ESP or baghouse.
