METHOD FOR PREPARATION OF WATER-BEARING FUEL-COAL SLURRY

摘要

FIELD: power industry.;SUBSTANCE: invention relates to a method for preparation of water-bearing fuel and coal slurry comprising M40 mazut dispersion, containing 1 % wt of water, in an amount of 60 % wt, grinding the dry coal in an amount of 40 % wt or dropout of it in a grinder to fraction less than 10 mm, supply of water-mazut mixture and pulverized coal in a mixer, mixing them in a mixer, subsequent supply of mixture to the next stage of dispersion of coarse grind, regrinding of slurry in a fine grinder, after which the slurry becomes homogenity and stable flow characteristics because of humic acids and humates extracted from coal.;EFFECT: increased calorific efficiency of fuel in form of a slurry.;3 tbl, 1 dwg
