A wind tunnel calibration is necessary in order to determine the calibration coefficient to obtain the flow velocity. An integrated thermocouple is used to measure the prism Pitot tube and a sphere Pitot tube, with corresponding sensing head diameters of 2.45 cm and 5.84 cm. The bodies of these 3D Pitot tubes are extended by 2 Smokestack Gas Velocity Measurements using 3-D Pitot

The Dirty Air Pitot (DAP) Probe is utilized to measure air velocity, pressure, and temperature within a flow stream that is heavily laden with particulate. Compared to other pressure-type velocity probes, the design of the DAP This calibration system can produce accurate pitch and velocity calibration curves for 3D pitot tubes. Then, these calibration curves will be used as references to Calibration process and uncertainty estimation for 3D pitot tubes

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• dirty pitot tube with a specific calibration constant is individual fuel pipe temperature were out by 5 to 20 c • dirty air flow distribution was found beyond +/- 5.0% in many mills • coal distribution would be with in accepatable limits for cases where in air distribution is normal front fired boiler • boiler is serviced by twoMills PDF Combustion Coal Scribd
