Seed-slag fouling and corrosion in an MHD steam bottoming plant
At the Argonne MHD Process Engineering Laboratory (AMPEL), five fouling tests have been carried out to investigate the deposition of seedash deposits that form on tubes in the convective sections of the MHD/steam bottoming plant. The effect of these deposits on heat transfer, their tenacity, composition, and effective thermal conductivities were determined. In these tests, combustion gas containing ash particles and K/sub 2/SO/sub 4/ was passed through a bank of 15 vertical, cooled tubes, which simulated a steam superheater or reheater. In addition to these fouling tests, long duration corrosion tests of commercial-grade metal alloys have been conducted in the laboratory under controlled conditions of gas and metal temperatures, gas chemistry, and deposit compositions. The tests completed to date support the premise that the convective sections of the MHD/steam bottoming plant can be designed to operate efficiently and reliably, and that suitable metal alloys are commercially available.
