“…Type of the dependence determined in experiments is similar to that one presented in [2][3][4][5][6][7][8][9][10]. Thus, in addition to the already known plasticizers, it is appropriate to apply as stabilizers the waste of petroleum-derived products, as well as oil refining, chemical and energy industries.…”

Abstract. 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.

“…Measured temperature in the droplet T d provided the opportunity to monitor the implementation of common criteria of ignition and complete combustion of the fuel composition. In line with the conclusions [14,15] as a criteria for sustainable ignition (for the considered system) we used: the simultaneous fulfillment of the inequality T d >T g ; achieving the rate of change T d not less 10 K/s. The combustion process was considered as a completed one when the temperature T d was corresponded to T g .…”

Abstract.To converge the conditions of organic water-coal fuel composition combustion in the typical power equipment we developed a new approach and installed an experimental setup, eliminating the traditional fixing the fuel droplets on the thermocouples or rods. Specialized cone-shaped chamber was used to implement the process of lingering of organic water-coal fuel droplets. Necessary and sufficient conditions for the lingering of organic water-coal fuel droplets were established. We determined the parameters of the system (droplet size of 0.4-0.6 mm, temperatures 823-903 K and the velocity of the oxidizer flow 1.5-6 m/s) at which the droplets were consistently ignited in the process of lingering. Minimum temperatures and ignition delay times of organic water-coal fuel droplets based on brown coal, used motor, turbine, transformer oils, kerosene, gasoline and water were defined.

Abstract. The laws of condition modification of inert heat and ignition in an oxidant flow of composite liquid fuel droplet were studied by the developed experimental setup. Investigations were for composite liquid fuel composition based on the waste of bituminous and nonbaking coal processing, appropriate carbon dust, water, used motor oil. The characteristics of boundary layer inertia heat of composite liquid fuel droplet, thermal decomposition of coal organic part, the yield of volatiles and evaporation of liquid combustion component, ignition of the gas mixture and coke residue were defined.
