ASME Coal Fineness Sampling Test Procedure Traverse points will need to be marked on the sampling probe based on an equal area test grid. Traverse points for a circular duct or pipe are calculated by first selecting the diagram below that corresponds to a 12" or larger pipe or a 10" – 11" pipe.
ASME Coal Fineness Sampling Test Procedure Rev. 3/2010 Page 1 2367 LAKESIDE DRIVE, SUITE A1 BIRMINGHAM, AL 35244 PHONE (205) FACSIMILE (205) The design of the ASME Fineness Sampler has been adapted from our longstanding Isokinetic Coal Sampler.
Importance of Fineness. Higher fineness levels always promote more even distribution of fuel between a pulverizer''s separate burner lines. Better distribution promotes better combustion, inherently lower NOx emissions and lower flyash or carbon content. The graph below illustrates actual test data on a pulverizer with varied fineness.
