CIRCUIT FOR GENERATING DUST Russian patent published in 2007 - IPC F23K1/00 

FIELD: power engineering.

SUBSTANCE: circuit comprises units for disintegration, separation, and accumulation of dust in the hopper, mechanism for ventilation of the dust system, unit for removing moisture from the hopper made of one or several pipes whose ends are connected with the ventilation (evacuation) mechanism and valves that control the moisture removing. The end of each pipe of the unit for removing moisture is connected with the ejector of the unit for removing moisture. The pipe of the unit for removing moisture is provided with valve having an indicator. The initial section of the pipe of the unit for removing moisture is mounted inside the hopper. The face entrance to the pipe of the unit for removing moisture is smooth. The ejector is mounted in block with the boiler burner. The level of outer end of the unit for removing moisture lies above the level of dust in the hopper. The hot air from the blowing fan or weakly heated air is used as an ejecting air in the ejector. The gate valve is mounted in the line of the ejecting air upstream of the ejector.

EFFECT: simplified circuit.
