Stabilizers of furnace oil-coal mixtures

ic acid with heating [1-3]. The properties of these polymers are cited in Table i. The objects of the study were coal from the Berezovo field of the Kansk-Achinsk coal basin (ash 5.98%, moisture content 6.61%, particle size less than 220 ~m) and furnace oil M-100 (viscosity at 70~ 0.03 Pa'sec, moisture content 5%). For the preparation of FCM we used a DS-106 disintegrator (linear speed of collision of a particle with the rotor pins is 120 m/sec) where coal is pulverized right in the liquid phase. The stability y of the suspension was determined by the gravimetric method using the equation [4] (in %): y~--- lOOa/(bc) where a is the weight of the solid substance in the analysis sample, g; b is the weight of the analysis sample, g; c is the weight of the solid substance in i00 g of the starting sample, g.
