ATOMISER Russian patent published in 2009 - IPC F23D11/00 

FIELD: heating systems.

SUBSTANCE: invention refers to power engineering and can be used for spraying combustible fluids in boiler furnaces. Atomiser consists of a body with a nozzle which is located in a hold-down nut screwed on a tubular body, and is made in the form of a flattened cone facing with its large base the furnace; inside the hold-down nut there fixed is a distributing washer with holes meant for fuel passage; in the nozzle there arranged is a nozzle plate which is also made in the form of a flattened cone facing with its large base the furnace and forming together with inner nozzle surface at its outlet a circular slot duct meant for fuel discharge; the nozzle plate is fixed on a cylindrical pin screwed into a distributing washer whereto on the opposite side attached is a stem on the end of which there fixed is a distributor made in the form of a cone the top of which is directed towards the fuel flow, and at that the hold-down nut and nozzle plate are made from heat-resistant material, and are located in the furnace arch.

EFFECT: improving flame firing efficiency owing to liquid fuel spraying and its homogenisation when fuel jets blow against the heated surface of distributor, inner surface of hold-down nut, and surface of nozzle plate.
