METHOD FOR SOLID CARBON-CONTAINING FUELS OR WASTES INCINERATION Russian patent published in 2017 - IPC F23K1/02 F23B90/00 

FIELD: power industry.

SUBSTANCE: method for solid carbon-containing fuel and/or waste incineration includes solid carbon-containing fuel and/or waste grinding, ground solid carbon-containing fuel and/or waste injection into the combustion chamber and initiation. The fineness of solid carbon-containing fuel and/or waste grinding is adjusted to a size less than 1 mcm to form a micronanocomposite mixture of gound solid carbon-containing fuel and/or waste with water, and then the resulting mixture is injected by means of a drop dispenser into a combustion chamber, wherein the said solid carbon-containing fuel and/or waste grinding particle size is effected in two stages, at the first stage - coarse grinding is performed, and at the second stage, grinding is adjusted to a size not greater than 1 µm using a cavitation dispersant. Initiation of combustion of droplets of the micrononocomposite mixture of grinded solid carbon-containing fuel and/or waste with water is carried out using a fuel supply unit by means of a fuel energy reserve, by which a flame is ignited in the combustion chamber.

EFFECT: invention makes it possible to increase plant reliability and efficiency by reducing parts wear and costs of fuel preparation.
