摘要
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 similar to 90A degrees C than that for a sample with no additive. 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 degradation and combustion.
