BURNER FOR CO-COMBUSTION OF LOW-POWER LIQUID AND LOW-ENERGY COAL FUEL Russian patent published in 2023 - IPC F23C1/10 

FIELD: energy.

SUBSTANCE: invention relates to burners for co-combustion of liquid and pulverized coal. The burner device for co-combustion of low-power liquid and pulverized coal fuel comprises a spray-ignition unit for burning atomized liquid fuel, comprising a cylindrical body in the form of a cup, on the upper end of which there is a nozzle in the form of a cover with a hole in the centre, and a unit for burning pulverized coal. The pulverized coal combustion unit is a cylindrical body, on both ends of which there are nozzles in the form of covers with holes in the centre of the same diameter, while one cover is docked with the nozzle of the spray-ignition unit. In addition, the pulverized coal combustion unit comprises pulverized coal nozzles mounted tangentially in the housing to create a vortex flow.

EFFECT: invention makes it possible to create a burner device for co-combustion of liquid and pulverized coal fuel, capable of operating at low power.
