High performance materials in coal conversion utilization. Technical progress report, July 1, 1995--September 30, 1995
This is the eighth quarterly report on a three year grant regarding ``High Performance Materials in Coal Conversion Utilization.`` The grant is for a joint university/industry effort under the US Department of Energy (DOE) University Coal Research Program. The University of Tennessee Space Institute (UTSI) is the prime contractor and the University of Pennsylvania and Lanxide Corporation are subcontractors. The object of this grant is to test, analyze, and improve the heat and coal-slag corrosion resistance of a SiC{sub (p)}/Al{sub 2}O{sub 3} ceramic composite tubular material. The material will be evaluated for its ability to withstand the pressures, temperatures and corrosion attack which would be encountered within a coal-fired high-temperature, high pressure air heater. The evaluation includes strength testing at elevated temperatures of production tubes as well as one manufactured with an innovative new technology. The feasibility of several joining and coating techniques are also being investigated. UTSI has completed all the initially planned laboratory exposure tests involving pulverized coal slag on the production Lanxide DIMOX{trademark} ceramic composite material. In addition, the strength testing (at temperature) and analysis of C- ring sections of the exposed production composite are complete.
