ABSTRACT:
A pressure-reducing device in a pneumatic transport system for particulate material having a first and a second transport channel which are arranged so that, at the transition between the two channels, the gas/particulate flow is bent through 180.degree.. After the bend, a throttling means is arranged. The throttling means consists of an annular nozzle, the inlet side thereof being rounded with an arcuate profile in radial section. The pressure-reducing device may be included in a transportation system for feeding particulate material out from a pressurized container to a container under a lower pressure, for example for removing dust from a dust separator in a PFBC plant to a collecting container.
