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.

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.
