Determining The Concentration Of Particulate Matter In A Gas Stream
The Test object is to determine the weight rate of flow of particulate matter carried in a gas stream confined in a duct or stack. The test object is accomplished by (a) measurement of average weight concentrations of particulate matter in the gas stream, and (b) determination of total gas flow rate. Data thus obtained may be utilized for such purposes as the performance evaluation of gas cleaning apparatus systems, compliance testing in conjunction with emission control and performance regulations promulgated by regulatory agencies, etc. 1.21 Concentration of Particulate Matter This Code prescribes methods for measuring the average weight concentration of particulate matter carried in a gas stream. Measurement on any other basis (e.g., particle count, dust spot, opacity, etc.) is beyond the scope of this Code. 1.23 Particle Size Measurement The scope of this Code does not include the measurement of particle size distribution. Test procedures for this purpose are contained in ASME Performance Test Code 28.
