Abstract The paper describes a particulate sampling train that satisfies the conflicting requirements of isokinetic sample extraction and constant flow rate through an inertial sizing device. A variable fraction of the filtered emission gas is added to the sample upstream of the inertial sizing device to maintain a preselected flow rate through the device, while the gas flow rate into the sampling nozzle is adjusted to remain isokinetic with the local duct velocity. The prototype emission gas recycl (EGR) train was constructed by relatively simple modifications of a commercially available Method 5 sampling system, and much of the sampling technique is identical with Method 5 protocol. The train was tested by comparing parallel runs in the EPA/SoRI wind tunnel using redispersed fly ash. In one series of runs performed without inertial sizing devices, the EGR train and a colocated non-EGR train sampled three-point traverses. (Copyright (c) JAPCA 1987.)
