FIELD: power industry.
SUBSTANCE: invention relates to fuel and power industry and can be used at disposal of bituminous coal benefication wastes. The coal-water and rock mixture combustion method involves its heating to ignition temperature from the external source. As an external source for ignition there used are prewarmed-up walls of the combustion chamber to the temperature of 1100°C, to which coal-water and rock mixture is supplied; air enriched with oxygen (3-5%) is supplied to the chamber, and the combustion zone is subject to action of ultrasound with frequency of 18-25 kHz.
EFFECT: invention allows disposing coal benefication wastes.
