Mechwell Industried Ltd. aaa Home. One set of ID fan FD fan PA fan Seal air fan and the Mill are started and PA header pressure (750800 mmwc) furnace draft (5 mmwc) and secondary air flow (30 ) are adjusted Pitot tube measurement is taken from inside the coal pipe at the centre of the coal pipe and air flow is adjusted to around 110 of the design air flow
A control circuit monitors the coal level in the mill, and controls the speed of the raw coal feeder to maintain it. Maintaining the coal level in the mill offers a builtin capacity cushion of pulverized fuel to take care of short interruptions in the raw coal circuit. The mill is pressurized and the airtightness is ensured by plenum chambers

DYNAMIC FLOW SYSTEM Specifications info DYNAMIC FLOW SYSTEM • Measuring Capability : Real time Coal Flow monitoring for up to 8 pipes per mill (no limitation for numbers of mills). • Measurement Range Mass Flow : 020 t/h for one pipe velocity : 1050 m/s
prerequisite to balancing coal flow among coal pipes. 3. Measure on a grid. The pitot tube measures clean air flow in a coal pipe based on an internal grid of at least 24 individual measurements representing equal flow areas. This measurement is made with no coal flowing into the pulverizers. Source: Storm Technologies Inc. Flow
In addition, the primary air flow rate through the mills is above 100 kNm 3 /h, whereas the historical operational values were between 80 to 100 kNm3/h. The higher primary air flow reduces the residence time of coal particles in the mills, reducing the grinding time and thus resulting in coarser coal particle sizes exiting the mill.
Coal is pulverized in the coal mill to a very fine particle size. The coal and primary air are then introduced to the coal nozzle. The coal and primary air are then introduced to the coal nozzle. Swirled air, coupled with the burner throat''s flowshaping contour, enables recirculation patterns that extend into the
duct mounted flow measurement device from any degradation in performance due to the presence of airborne particulate (flyash). Engineering Testing Services. AMC Power offers complete engineering and testing to analyze air and coal delivery systems. AMC Power''s field testing services use 3D airflow traversing and PfFLO coal flow measurement
Coal Plant Dirty Air Testing. clean air flow test coal mill 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
