Abstract—The results of thermogravimetric experiments showed that the temperature of a maximum weight
loss rate of anthracite with 5% K₂CO₃ on combustion was lower by ~90C than that for a sample with no addi-
tive. The effect of the additive was explained by the thermionic emission of electrons from potassium metal,
which was formed in a redox reaction: a portion of electrons bombarded the anthracite surface to secondary
electron emission—the emission of electrons by the organic matter of anthracite and the acceleration of its deg-
radation and combustion.
