Clean air balance is defined as balance of airflow between a pulverizer’s fuel lines in the absence of fuel • This is achieved by forcing air through the pulverizer at normal operating mill outlet temperatures with primary air fans while the feeder remains off line Clean air balance is determined by measuring the velocity of airkeeping mill in healthy condition Clean air flow test based on test results orifices can be adjusted in coal pipes to achieve clean air flow balance within / 5 Dirty air flow test Results will ensure fuel flow balance within / 10 and will help to know velocity through each pipe along with fineness of coal through each pipe

When a mill is brought down and swept with air the mill eventually is free of coal but there is still some residual dust/ash blowing through the pip There is no coal density so the MF=0 Density x Vel = 0 This “clean air” velocity was compared to clean air tests performed by Alstom The accuracy of the Pf FLO “clean air test velocity with the actual coal particle velocities in the coal pip Our approach to measuring dirty airflow in coal pipes fuel and air is to assemble a dirty airflow test kit Figure 2 and an isokinetic coal sampling test kit to collect representative fuel samples for coal fineness analysis Figure 3
