| titleOfInvention | Method of producing coal-water fuel and production line for accomplishment thereof |
| abstract | FIELD: alternate fuels. n SUBSTANCE: invention relates to fuel power engineering, in particular to methods for production of coal and water-based fuels, to which other components are added, which fuel is appropriate to be directly combusted in boilers, furnaces, and various power installations instead of dry coal and mazut, and which fuel is also appropriate for pipeline transportation. Method comprises crushing coal in hammer crusher into fraction 0-10 mm, coarsely grinding resulting solid constituent in cavitation mixer, while simultaneously demineralizing it, and finely grinding for example solid fuel product in cavitation mixer with water. Into coarse-grinding cavitation mixer are added 0.005% of alkali reagent, up to 3.5% of coal-stabilizing additive, and water to maintain pulp in fluidized state. Suspension thus obtained is sent to hydroclassifier to separate coal particles larger than 800 μm in size and mineral particles. Separated mineral and coal particles are loaded into hydrocyclone to separate coal particles recycled into mixer, while minerals are discarded. Suspension freed from coarse coal fraction and minerals is loaded into fine-grinding disperser to produce solid phase particles up to 250 μm in size, wherein suspension components are subjected to second simultaneous after-disintegration and stirring, after which mixture is sent to accumulation and storage tank, wherefrom it is supplied to boiler burners. Proportion of coarse-grinding solid constituent in cavitation mixer is 60-75%. Invention also discloses production line comprising mainly coarse- and fine-grinding cavitation mixers, which have bodies, rotors provided with rotor rings and stator rings, aspiration pipes, and pressure conduits, holes in rotors being made in the form of round-cylindrical Venturi nozzles and those in stators in the form of suddenly expanding nozzles. Cavitation grinding of coal, as well as other hydrocarbon substances, by coarse- and fine-grinding dispersers in aqueous medium favors evolution of gaseous (methane, 9%) and liquid phases, which improves rheological properties of suspension and reduces inflammation temperature thereof. n EFFECT: enhanced process efficiency, reduced power consumption, enabled production of high-calorific fuel employing simplified technology. n 3 cl, 5 dwg |
