Coal plasticity at high heating rates and temperatures. Eleventh technical progress report, fourth quarter, October 1, 1992--December 31, 1992

摘要

The report elaborates upon our earlier discussion (Technical Progress Report No. 9) of heating rate effects on the plasticity of coals from the Argonne premium sample bank. Apparent viscosity vs. time curves are presented for five of these coals. As reported earlier, heating rate had relatively little effect (typically t 20 K) on the softening temperature of these coals. The results presented here show that as heating rate is increased from 200 to 800 K/s, the plastic period for each of these coals decreases.
