Sampling of tangential flow streams.
The causes and characteristics of tangential flow in industrial stacks are described. Errors induced by tangential flow in the determination of volumetric flow rate and particulate concentration are analyzed. Experiments were conducted at the outlet of a cyclone collector in order to investigate the effect of tangential flow on the determination of emission rates. Straightening vanes were found to be useful in the reduction of error in flow rate measurements.
