ISO 9931 Pulverized Coal Flow Measurement System The ISO 9931 Measurement System is utilized to sample particulate flow carried within an air stream. By isokinetically extracting the sample, the particulate flow rate can be determined. The sampling probe, the SwivelSamplerTM, features four (4) nozzles that rotate around the center axis, and thus the probe is ideally suited .
In the pulverized coal storage system, the coal after pulverization is conveyed into bins. Collection of Gross Sample—Collect not less than ten increments of representative pulverized coal preferably as it is being discharged from the collector. This is best accomplished by collecting increments of not less than 50 g at regular
