Abstract

In
this paper, a mathematical model for
the removal of volatiles
from lignite grains is presented.
Total amount of volatiles
in the dry lignite, experimentally
determined, is 44.53%.Such high presence of volatiles makes
the lignite reach its ignition temperature very quickly. Methodology of this
research is based on laboratory research and the designing of the model for
devolution, based  on famous equations of
different authors, and the programs Microsoft Excel and Mathlab. Results of the
simulation are generated for grains with varying activation energy.
Distribution function is continuous (E) with f(E)dE which represents the
fraction of possible released volatiles Wj,lim with
activation energy within E and E+dE.

Keywords
