This calibration system can produce accurate pitch and velocity calibration curves for 3D pitot tubes in the range of testing pitch angle within ±30°, and have an expanded uncertainty attributed to the calibration curves () and ()% for the prism pitot tube and () and ()% for the spherical pitot tube.
Ans: clean air test is conducted on standby coal mill or coal mill during shutdown and dirty air test is conducted on running coal mill. What are the benefits of this activity? Ans: ... Ans : Instrument used for this testing is " Pitot tube, Manometer, isokinetic kit. etc. " How much time is required for this test?
1. Balancing act. Combustion tuning of a pulverized coal boiler begins with balancing the air and fuel flows in the coal pipes from the pulverizers to the burners. Note that each of the coal pipes is a different length. On most boilers, burners are also present on the opposite side of the furnace, adding to the air/fuelbalancing challenges.
Two types of 3D Pitot tubes are used to carry out the stack velocity measurements in this research, a prism Pitot tube and a sphere Pitot tube, with corresponding sensing head diameters of cm and cm. The bodies of these 3D Pitot tubes are extended by 2 m to be compatible with the measuring condition at the smokestack. Calibration

The answer lies in a small metal tube protruding out into the airstream and a tiny hole in the aircraft fuselage. This seemingly simple setup runs three of the most important instruments in the cockpit. It is called the pitotstatic system. The pitotstatic system is used in aircraft to measure the aircraft's airspeed, altitude, and vertical ...
Dirty airflow testing and isokinetic coal sampling are performed to: Ascertain the dirty airflow and fuel flow balances for each mill. Determine the mill grinding performance through coal fineness analysis. Provide a correlation between fuel line "dirty air" velocities and fuel balance.
The Pitot Tube Where to use a Pitot Tube Anemometer. If you are familiar with the vane anemometer, then you can relate to this easily. It has the same application but with a different method and approach of measurement. A pitot tube is used to measure the velocity of air in a duct with just a small opening.

Keep in mind that coal is about a thousand times denser than air and is a solid. The smaller the particles, the more the solid fuel parMeasuring Coal Pipe Flow Coal pipe flows can only be balanced and optimized when they are measured. Until you have confidence in your coal flow measurements, tuning the pulverized coal boiler is simply guesswork.

The dirty air pitot probe is utilized to measure air velocity, pressure, and temperature within a flow stream that is heavily laden with particulate. Compared to other pressuretype velocity probes, the design of the dirty air probe reduces the potential for pluggage of the pressure lines, a situation that will cause erroneous data.
