METHOD FOR TWO-STAGE COMBUSTION OF COAL-WATER FUEL WITH CERAMIC FLAME STABILIZER AND ILLUMINATION Russian patent published in 2019 - IPC F23C6/04 F23C99/00 

FIELD: energy.

SUBSTANCE: invention relates to heat engineering. Method of two-stage combustion of coal-water fuel with ceramic stabilizer of burning and illumination, in which two combustion chambers are used, combustion process takes place in two vertically arranged chambers separated from each other by horizontally installed ceramic grate, fuel and air are simultaneously supplied to each chamber, fuel-air mixture is ignited from electric high-temperature element, in process of combustion there is a redistribution of fuel fractions, lighter fractions burn in upper chamber, heavier ones under action of gravitation forces fall into lower chamber, where burn at higher temperature, ceramic honeycomb grates separate upper combustion chamber from lower and lower combustion chamber from sludge tray and perform function of combustion stabilizer, in lower combustion chamber higher temperature is created due to additional heating by electric heating element, same element performs function of fuel ignition at start-up moment.

EFFECT: invention ensures stable combustion of water-coal fuel in small furnace spaces, which in turn will allow using cheap water-coal fuel for heating of small rooms (up to 1,000 square meters) and reducing emission of hazardous substances into atmosphere.
