ASME PTC 38
Determining the Concentration of Particulate Matter in a Gas Stream
Organization:
ASME - ASME International
Year: 1985
Abstract: 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.
Gas Flow Measurement
Determination of total gas flow may be based on measurement of velocity pressure and gas density at representative points in the duct cross section, on actual combustion calculations (stoichiometry), or by data from calibrated gas metering devices. Alternate methods for measuring total gas flow rate may be used by agreement of all the concerned parties.
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. While some in situ type samplers designed for the collection of particulate matter in various size fractions may have a limited capability for determining total particulate matter concentrations in a gas sample, data thus obtained should only be used for the measurement of particle size distribution and not for the weight rate of flow of particulate matter in the gas stream.
