COMBUSTION AIR (CA) STATION

The Combustion Air (CA) Station is a multi-point, self averaging Pitot traverse station designed to provide accurate and repeatable primary, secondary and/or tertiary airflow measurement in gas, oil or coal fired power plants. The CA Station with its integral air straightener-equalizer honeycomb cell can be installed in extremely short duct runs and is capable of measuring airflow within 2-3% of actual. The rugged designed multi-point Pitot tube traverse station offers a high degree of measuring accuracy by virtue of precisely located sensors, honeycomb airflow processing, and instantaneous pneumatic averaging of multiple differential pressure sensors. For installation into duct sizes ranging from 12" diameter up to 30’ x 30’, the CA Station can measure airflow reliably in high temperature and heavy particulate environments. Installation of the CA Station will assist in optimizing air to fuel ratios, and therefore increase power plant performance while lowering NOx emissions levels.

COMBUSTION AIR (CA) STATION FEATURES
 
  • Accuracy: 2-3% of actual flow.
     
  • Air Equalizer – Straightener Cell: Carbon steel .022" thick. 3" deep x 1" cell. Stainless steel optional.
     
  • Casing: 3/16" thick carbon steel 12" deep with 2" flanges. Stainless steel optional.
     
  • Configurations: Rectangular, and circular.
     
  • Negligible Resistance to Airflow: Cylindrical configuration and smooth surface free of external sensor protrusions permit the airstream to flow unrestricted, creating negligible pressure drop.
     
  • Operating Temperature: Continuous operation to 900F.

 
  • No Sensor Protrusion: Contained within the confines of the external surface of the probe.
     
  • Total and Static Pressure Headers and Sensors: Stainless steel tubing assembly by TIG welding. Stainless steel mounting and support brackets.
     
  • True Velocity Pressure Measurement: The measured total and static differential pressure components of airflow can be directly converted in velocity pressure (and velocity) without the use of correction ("K") factors.
     
  • Temperature Sensor: Integral temperature sensor can be provided to measure duct temperature for mass flow calculations.
