Flue Gas Velocity Determination with S Type Pitot Tube: Efficient Measurement Methods

Flue Gas Velocity Determination with S Type Pitot Tube

What is a Pitot Tube and How Does it Work?

A Pitot tube is a device used to measure air flow velocity. It calculates the velocity of the air flow by measuring two different pressures. The S Type Pitot Tube is a variant of this type of device and is especially preferred for flue gas measurements. Basically, the Pitot tube measures pressure at two points:

1. Static Pressure (Pₛ): The pressure in the non-moving part of the gas.
2. Dynamic Pressure (Pₖ): The pressure in the moving part of the gas.

The difference between these two pressures is used to calculate the air flow rate. The Pitot tube measures this pressure difference and allows the velocity to be calculated. The S Type Pitot tube has a structure that can measure two pressures more precisely and give more accurate results.

Why Use S Type Pitot Tube in Flue Gas Velocity Measurement?

1. Accurate and Precise Measurement: S Type Pitot tubes have the capacity to make accurate measurements, especially in heterogeneous and complex gas mixtures such as flue gas. In this way, it is possible to precisely determine the flue gas velocity.
2. Compliance with Environmental Regulations: Accurate measurement of flue gas velocity is essential to ensure compliance with environmental regulations. This measurement plays an important role in setting emission standards to reduce environmental pollution.
3. Energy Efficiency Monitoring: Flue gas velocity monitoring in industrial plants is used to evaluate the energy efficiency of the system. Measurements with the S Type Pitot tube provide accurate monitoring of gas flow and help to develop energy saving strategies.

Flue Gas Velocity Measurement

The pitot tube used for flue gas velocity measurement is inserted into the duct with its tip facing the air flow and the positive port of the manometer is connected to the total pressure port and the negative port to the static pressure port. The manometer indicates the velocity pressure, which can then be converted to velocity. Pitot tubes are well suited for medium and high velocity airflow measurement. It is recognized as a standard to which all other airflow instruments are compared. Accurate measurement during use requires density correction and careful movement.

Accuracy is determined by the pressure measuring device attached to the pitot tube and there are often more economical ways to measure airflow in low flow applications. For high flow or high temperature applications, the pitot tube is considered ideal. The pitot tube measures the total pressure and static pressure to determine the air velocity pressure. In modern pitot tubes, the appropriate nose or tip design is such that turbulence and interference are minimized. The S-type pitot tube is manufactured by welding two identically shaped and hollow metal tubes together.
