Pulverized Coal Pipe Testing and Balancing

2016-5-3 · With near 0% remaining on the 50-mesh sieve, at least three points are needed on the Rosin-Rammler Chart to plot the fineness results. Four sieves of 50, 100, 140, and 200 mesh are recommended for fineness sampling. Fuel line fineness should be 75% or more passing a 200-mesh screen and a maximum of 0.1% remaining on the 50-mesh screen.

Fineness

The fineness of the milling product and the capacity of the pulverizer are strictly connected. With increased fineness grows the overall circulation rate of coal in the mill, coal retention time and the flow resistance. As a result, the maximum mill capacity decreases and the rate of change of operational parameters of the furnace system deteriorates.
