FIELD: study of grading composition of flow of particles during test of atomizers working on coal-and-water. SUBSTANCE: method of determination of grading composition of flow of particles of atomized liquid involves trapping of particles in immersion medium followed by their counting and measurement. Microencapsulation of trapped particles of atomized liquid is performed in immersion medium, dried capsules are subjected to grading in sieves and obtained samples are weighed. Microencapsulation is conducted by method if interphase polycondensation. Coal-and-water suspension can be used in the capacity of atomized liquid. Interphase polycondensation is carried out by preliminary injection of polyethylenepolyamine into coal-and-water suspension and of polyisocionate into immersion medium. Oil nonpolar liquid is used as immersion medium. EFFECT: enhanced of method. 3 cl
