Abstract
The problem of heat and mass transfer has been solved numerically
under the conditions of coal-water fuel particle ignition. The concurrent processes of evaporation,
filtration of steam, thermal decomposition of the organic part of coal, thermal
and chemical interaction of steam and coke carbon, and oxidation of products of
their reaction and volatiles by the external oxidizer have been taken into
account. The scales of influence of individual thermophysical and
thermochemical properties of coals on the characteristics and conditions of
ignition of coal-water slurry have been determined.
