DETERMINATION OF SECTIONAL CONSTANCY OF ORGANIC COAL-WATER FUEL COMPOSITIONS.

To use widespreadly the waste of coals and oils processing in the great and the small-scale power generation, the key parameter, which is sectional constancy of promising organic coal-water fuels (OCWF), was studied. The compositions of OCWF from brown and bituminous coals, filter cakes, used motor, turbine and dielectrical oils, water-oil emulsion and special wetting agent (plasticizer) were investigated. Two modes of preparation were considered. They are with homogenizer and cavitator. It was established that the constancy did not exceed 5-7 days for the compositions of OCWF with brown coals, and 12-15 days for that compositions with bituminous coals and filter cakes. The injection of used oils in a composition of OCWF led to increase in viscosity of fuel compositions and their sectional constancy. [ABSTRACT FROM AUTHOR]
