In a Dirty airflow test, the temperature, static pressure and DP across the pipe cross-section are measured to calculate coal / air mixture velocity and flow in each PF pipe. The velocity and flow measurements of ‘dirty air’ (coal air mixture) are done under defined operating conditions
Oct 07, 2010 Dirty airflow measurements are also useful in determining the level of mill performance (mill air in-leakage values—on suction mills), mill heat balance calculations, airflow balance, and the …
B] Dirty Air Test Process :- Tests ports are installed on coal pipes to facilitate clean and dirty air traversing using pitot tubes and dirty air probes. Optimum location for these taps should be between five diameters downstream and ten diameters upstream of the nearest elbow or change of direction.
Mill Dirty Air Flow Ch-8.6 wbpdclewf.in. mill discharge pipes for checking the fineness fractions. This methodology is suitable for sampling from vertical circular pipes only. In a Dirty airflow test, the temperature, static pressure and DP across the pipe cross-section are measured to calculate coal / air mixture velocity and flow in each PF pipe.
The first test conducted by a testing crew is the dirty air traverse. That test uses the same sampling points when measuring velocities in the pipes. By measuring the true velocity flowing through the pipe, guessing an unknown velocity, as required by the ASME test procedure, is eliminated. After the dirty air velocity test is completed, the coal is sampled.
Dirty Air Velocity Probe has now been calibrated in clean air flow How accurately does it measure air velocity in the presence of coal? Test matrix: Air Velocity (ft/sec) 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 Clean 75 X X X X X 95 X X X X X 110 X X X X X Air/Coal Ratio
