Technical Support for the Scientific Information Exchange Program Between Polish People's Republic and US Department of Energy. Final Report, May 12, 1980-September 30, 1981.

摘要

The overall objective of this cooperative Scientific Information Exchange program is to determine the effects of certain operating parameters on the plasma generated by the 4-5 MW MHD coal combustor in Swierk, Poland. These parameters included: (1) coal type, (2) coal moisture content, (3) seed injection, (4) slag removal, (5) coal size distribution, (6) equivalence ratio, and (7) NO/sub x/, CO and SO/sub x/ content in the exhaust gas. Progress is reported, and an addendum is included on slag rejection and mineral matter behavior in an MHD cyclone combustor. The amount of ash rejected as slag through a tap in the bottom of an MHD cyclone combustor is studied as a function of: (1) particle size of the coal injected into the combustor, and (2) the mineral matter behavior prior to its deposition on the walls of the cyclone. The study relates to tests performed by Polish workers who, in their comparison of the behavior of Polish and US coals in a cyclone burner, reported widely different levels of ash rejection. Details are presented. (ERA citation 08:036111)
