ABSTRACT:
A method of feeding out dust in a dust discharge system in a power plant including feeding out dust pneumatically from a separator via a suction nozzle by using transport gas with a pressure exceeding atmospheric pressure, supplying diluting gas into the transport gas at a location close to the suction nozzle of the dust discharge system, and selecting the flow of diluting gas into the transport gas so that part of the pressure drop (.DELTA.Pgas) of the transport gas across the dust discharge system (.DELTA.p) is maintained.
