Method and device for continuous removal of a part of a gasstream.

摘要

To regulate the volumetric flow of the part continuously removed from a gas stream and fed to a gaseous dilution stream for continuous mixing, this part, after branching off from the gas stream and before the mixing with the dilution stream, is passed through a baffle area (17) to which a controllable control stream is fed, as a result of which a pneumatic orifice avoiding mechanical cross-sectional changes in the guidance of the part of the gas stream is created. ……
