Combustion air pipe

Combustion air flow and volume measurement

过程数据

测量任务:
Differential pressure measurement
测量点:
Pipeline
测量范围至:
0 … 30 mbar
介质:
Air and coal dust
过程温度:
+200 … +400 °C
过程压力:
0 … 1 bar
特殊挑战:
Very small measuring ranges, high temperatures

应用范围

To ensure an optimum combustion process in a coal-fired power plant, the amount of air flowing in the pipes leading to the furnace must be carefully monitored. A Venturi section of the air pipe is a defined constriction in which the pressure drops a few millibars proportional to flow rate. VEGADIF 65, with its especially small measuring range and high accuracy, measures this pressure drop with great precision and calculates the air flow.
