Coal plasticity at high heating rates and temperatures. Tenth technical progress report, third quarter, July 1, 1992--September 30, 1992

Abstract

Effects of coal type on coal plasticity are investigated. Seven coals, from the Argonne premium sample bank ranging from lignite to low volatile bituminous, are studied. Different indices and structural data of a coal are shown to affect its plastic behavior. A coal-specific parameter incorporating the effects of labile bridges, oxygen, and hydrogen on plasticity has been used to successfully .correlate measured values of maximum plasticity (i.e. minimum apparent viscosity) at elevated temperature with coal type.
