Method and means to estimate porosity distribution on the surface of polished section of coal

The method is based on transcapillary penetration of fluorescent fluid (EpoDye colorant) in the finest cavities and flaws on the surface of polished sections. Luminophor-filed voids become visible

Mechanism of primary fragmentation of coal in fluidized bed

In order to lay a foundation of a credible primary fragmentation model, a theoretical analysis of the thermo-mechanical processes in a devolatilizing solid fuel particle was carried out. The
