  • ASME Coal Sampling Test Procedure

    Rev. 3/2010 Page 4 The proper procedure to collect coal samples using the ASME Coal Sampler is as follows: • Insert the sample probe into the dustless connector, open the ball valve, and slide the probe in to the first port (probe completely inserted) with the flag oriented in the direction of flow (which enables the sample tip to collect pulverized coal from the burner line).
