Heat capacity and Thermal conductivity consideration for coal Particles During the Early Stages of Rapid Heating

摘要

Heating and cooling transients for a number of individual coal particles in the 100-μm size range were measure under rapid heating conditions (10~4-10~5 K/s heating rate). In addition to temperature measurements, each particle was fully characterized with respect to external surface area, volume, mass, and density prior to heating. Measured temperatures were compared with model predictions and a sensitivity analysis was performed to critically evaluate model assumptions regarding particle thermal properties.
