FIELD: technological processes.
SUBSTANCE: invention discloses the pulverized coal fuel for combustion preparation method, including the raw coal drying and crushing, at that, before crushing at this coal the modified sodium silicate (MSS) is applied, having the coal dust surface high wetting coefficient, formed during the coal grinding process, and the particle surface filling degree with a film at the mill exit should be from 10 % to 30 % of this particle total surface.
EFFECT: with its use enabling the pulverized coal fuel efficient combustion with the more environmentally friendly high-temperature flame formation with reduction in the nitrogen oxides emissions, and also reduction in the dust formation, the boilers explosion hazard and slagging.
