PROMECON GmbH Real time EAF off-gas measurement


PROMECON | Electric Arc Furnace Off-Gas Analysis

directly at the furnace outlet

The 3rd generation off-gas analyzer McON IR offers numerous advantages to opreators of electric arc furnaces.
At our booth we will show you how to optimize your melting process by exhaust gas measurement.

What can you expect?

  • Measurement of off-gas flow and composition (gas velocity, CO, CO2, CH4, H2O) up to 2500°C
  • High cost savings (electric consumption, oxygen, tap-time)
  • Water detection (high process safety)

What makes your life easier?

  • measure in real-time (fast reactions to process deviations)
  • no drifts (no more calibrations after installation)
  • non-extractive (no addtional measurement efforts)
  • non-intrusive (minimal wear and tear, long sensor life)
  • very low maintenance effort

EAF Off-Gas Moniroting with McON IR by PROMECON

 Press Releases

  • Barleben, Germany, February 22, 2023      At AISTech, PROMECON will present the McON IR system for rapid in-situ measurement of the composition and volume of off-gas at electric arc furnaces. The measured values can be used to improve the utilization of the chemical energy in the off-gas and minimize thermal off-gas losses. They can also reduce the energy requirements of the furnace, enabling optimization of the complete process.

    Until now, measuring the off-gas from electric arc furnaces involved intrusive sensors or extractive measurements in the exhaust gas channel, which only provided the measured values with a delay or required high maintenance. In contrast, the new McON IR sensors operate on an infrared basis and do not require lances protruding into the off-gas duct. They measure chemical composition as well as the velocity and temperature of the off-gas stream directly at the off-gas manifold.

    The system's infrared detector captures a large portion of the cross-section of the off-gas duct. The sensor measures the active infrared emission of individual gas molecules and uses this to determine the concentration of gases such as carbon monoxide, carbon dioxide and methane; it also detects water in the exhaust gas stream - an aspect that is playing an increasingly important role in safety at the melting furnace. A second pair of sensors measures the flow velocity and temperature of the off-gas.

    The sensors are installed immediately after the ventilation slot (4th hole) on the manifold - very close to the furnace. Since no components protrude into the cross-section of the pipe, installation between the water-cooled piping is very simple. The optics are purged with nitrogen, and the sensor electronics are cooled. The protected cable routing with additional flame protection help the sensors achieve service lives of up to twelve months. Also due to low maintenance requirements, the new sensors have a significantly higher availability compared to other intrusive systems.

    Hans Georg Conrads, Managing Director at PROMECON, sees great potential for minimizing the energy requirements of electric arc furnaces with the new system: "The new McON IR sensors work so fast that the measurement results can be used for real-time control of the furnace, for example with the oxygen lances or the gas burners."

  • McON IR - The innovative off-gas analyzer for EAFs
    The McON IR is an 3rd generation online, non-intrusive and non extractiv analyzer for the off-gas Analysis directly at the Electric Arc Furnace (EAF) outlet. Customers are convinced by minimum maintenance as well as real-time and drift-free mesurement....

  • Optimize your smelting process and save enormous amounts of energy

    With the 3rd generation of EAF monitoring, PROMECON sets new industry standards. The power of an effective and accurate off-gas monitoring of the electric arc furnace (EAF) leads to enormous energy and human labor savings.

    In comparison to monitoring devices from former generations, the McON IR comes with multiple advantages with regards to practicability, availability of the measured values as well as calibration and maintenance efforts.


    What can you expect of the off-gas monitoring with McON IR?

    • See the off-gas composition
      • CO/CO2 ratio,
      • CH4 content,
      • H2O detection
    • Measure the complete duct diameter, not only a small range
    • Fast response times - Measuring results are available after 1-2 seconds after the measurement
    • non-intrusive measurement - no parts sticking out into the pipe
    • minimum maintenance effort
