All coal pipes (and flows to all of the burners June 2003, Vol. 21 (2) FIELD TESTS CONFIRM EFFECTIVENESS,1999), the coal flow control technology was installed and tested at two coal-fired power plants. One installation involves a boiler with CE Raymond Bowl mills with exhauster fans. Three-way splitters with rifflers at the exit of the exhauster fan distribute the coal from each mill to three burner lines. The three-way riffler consists of 24OPUS at UTS: Distribution of pulverized coal flow in a,In this work, measurements were carried out at 5 reduced loads ranging from 35.5% to 60.1%. The coal is carried in each fuel pipe by 11.5 to 17 kg/s of air flow. The desired distribution is that fuel is evenly split among all the pipes, namely 25% of the total coal in each mill pipe, and half of that amount in each of the 8 burner pipes.
