Description:
The objective of this program was to evolve a method for the automatic determination of the size distribution of particulates within stack gas effluent streams. This device was designed to cover the typical mass concentration range encountered upstream as well as downstream of emission control systems, and to segregate the particles by means of a cascaded virtual inertial impaction configuration to be inserted into the effluent stream. Several alternative particle detection techniques compatible with this size segregation method were investigated in the course of this program and a stage filter pressure drop sensing technique was selected. The prototype device was subjected to laboratory and stack testing showing very good correlation with an Andersen-type impactor. The salient advantages of this instrument are: capability for extended operation (of the order of hours), real-time indication of size distribution of particulates in the stack environment, relatively low cost, and simplicity of operation.
