Pitot tubes are small portable devices that gauge how well this CEMS ultrasound system is doing its job. Each year, technicians use pitot tubes to conduct what’s called a Relative Accuracy Test Audit (RATA). To conduct the audit, they insert a pitot tube into the smokestack horizontally. The tube …
• Material – 304 stainless steel, seamless stainless steel tube • Calibration – At 10 velocities in the range of 25 ft/sec to 150 ft/sec. Airflow Sciences Equipment LLC – Clean Air Pitot Page 1 of 2 Velocity testing in a coal piping system Pressuresensing head design for clean air probe (SType)
Calibration factor of a multi-hole Pitot tube as a function of air speed at turbulence intensities of 0.27% to 2.0%. (pitch = 20°; yaw = 0°) The arrows show that, at low turbulence, the calibration factor is smaller with increasing air speed than with decreasing air speed.
Aerated ball tube mills are designed for anthracites, coal, lignite, shale and other materials grinding up to pulverized condition and for continuous operation in coal pulverization systems at thermal power plants and other branches of industry.
SDF-Sensors are using the averaging pitot tube technology and can be used wherever flow rates of gases or liquids are to be measured. They have been proven in practice to be reliable, stable and accurate for more than 25 years.
Types of coal pulverizers. Coal pulverizers may be classified by speed, as follows: Low Speed; Medium Speed; High Speed; Low speed Ball and tube mills. A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods.
