A pulverizer or grinder is a mechanical device for the grinding of many different types of materials. For example, a pulverizer mill is used to pulverize coal for combustion in the steam-generating furnaces of fossil fuel power plants.
The first phase consisted of commissioning the coal flow and air flow measurement systems and subsequent continual A/F balancing through automation of Secondary Air flow actuation systems. Through ...
Airflow Sciences Equipment, LLC Clean Air Pitot Probe The clean air pitot probe is utilized to measure air velocity, pressure, and temperature within a flow stream. It uses a standard S-Type pitot probe to measure velocity and is thus in compliance with EPA Method 2 test procedures. The probe is connected to a pressure gauge or electronic pressure transducer to measure the differential. A wind ...

Air Velocity in a Pipe Using the equation and typical values of V, D and L explained to the right approximate values of P are computed as follows: V = air velocity in feet per second
These systems utilize air pressure above 15 psig (up to 50 psig) in the pipe and use positive pressure to push materials through the conveying line at relatively low velocities (from 100 fpm to a maximum of 1000 fpm) much like extruding.

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 ar-eas. This measurement is made with no coal flowing into the pulverizers. Source: Storm Technologies Inc. Flow Total pressure Static pressure Static pressure 10“ incline manometer 4. Minimize flow variation. On the left (4b) is the “as found ...
Flow velocity in air or water is often measured with a Pitot Tube, as shown in the figure at the left. The impact tube faces directly into the flow, while the static tube is perpendicular to the flow. Both functions can be combined in a single unit. From Bernoulli's equation, p
For flows at lower pressure, consult more complete references. The above are representative flows for estimating purposes. Wall thicknesses are: 1/8" tube, 0.21" wall; 1/4" tube, .035" wall.
Building owners must monitor the flow through air duct grills to test how well their ventilation systems work. A pilot tube assembly, a device containing multiple probes, measures the static pressure drop between the grill’s two sides.
Static Pressure is the resistance to airflow (friction) caused by the air moving through a pipe, duct, hose, material. There is a variation of axial flow duct fan that uses a blower wheel instead of a propeller.
Spirometry measures the rate of air flow and estimates lung size. For this test, you will breathe multiple times, with regular and maximal effort, through a tube that is connected to a computer. Some people feel lightheaded or tired from the required breathing effort.
