Dielectric Heating in Mixtures Containing Coal and Pyrite

摘要

Run-of-mine (ROM) coal was separated by gravitational techniques into fractions designated as 1.30 float (clean coal) and 2.00 sink (pyrite and ash). Dielectric properties were measured and used to predict heating rates. Predicted values suggested that pyrite and ash would heat from 1.3 to 3.3 times faster than clean coal. Dielectric heating was investigated by heating mixtures containing these two fractions at 2.45 GHz. Results indicated that the pyrite and ash fraction was heated from 1.9 to 2.6 times faster than clean coal. (ERA citation 05:028364)
