Enhance Safety in Coke Oven Operations with the GasTDL-3100 Oxygen Analyzer

In the steel production industry, maintaining the safety and efficiency of coke ovens is crucial. Coke, a key material in steel production, is manufactured by heating coal in oxygen-deficient environments, resulting in the release of syngas, which contains combustible gases such as H₂, CH₄, and CO. These combustible gases can pose a significant explosion risk if the oxygen concentration reaches certain levels. According to the Safety Data Sheet from United States Steel, the explosion limit for syngas in coke ovens ranges from 4% to 75% oxygen.

To ensure safety and prevent catastrophic events, it is imperative to monitor the oxygen levels in real-time, keeping them below 2% to mitigate explosion risks. While conventional electrochemical or Zirconia sensors with extractive sampling methods frequently struggle with delayed response times (typically >30 seconds), calibration drift, and susceptibility to environmental interference, posing risks in time-sensitive safety scenarios.

Recognizing these limitations, Cubic Instruments, a leading manufacturer of advanced gas sensors and gas analyzers, has developed the GasTDL-3100, an in-situ laser gas analyzer that provides real-time oxygen concentration monitoring specifically tailored to harsh industrial environments.

Built on cutting-edge Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology, the GasTDL-3100 delivers superior performance even under the most demanding conditions, including high temperatures, high dust loads, and humidity, typical in coke oven environments.

Why Choose GasTDL-3100 for Your Coke Oven Safety?

  • Fast Response Time: With a T90 response time of less than 1 second, the GasTDL-3100 enables quick detection of oxygen fluctuations, allowing operators to act swiftly to mitigate explosion risks.
  • Exceptional Accuracy: The analyzer offers an impressive measurement precision of ±1% F.S., ensuring highly accurate oxygen level readings and preventing false alarms that could disrupt normal production processes.
  • No Cross-Interference: With high selectivity for oxygen, the GasTDL-3100 operates without interference from other background gases, providing reliable and consistent readings in the complex environment of a coke oven.
  • Explosion-Proof and Durable: The Exd II CT6 certification ensures the GasTDL-3100 is explosion-proof and safe to use in hazardous environments, while its design without moving parts guarantees low maintenance and long-term reliability.
  • In-Situ Installation: The TDLAS optical measuring principle allows for easy installation directly in the process stream without the need for sampling or conditioning.  The in-situ installation feature simplifies setup, reduces maintenance costs, and ensures continuous monitoring.


In conclusion, the GasTDL-3100 is the ideal solution for safety monitoring in coke ovens, ensuring operators can maintain optimal oxygen levels and protect against potential explosions. The combination of speed, precision, and reliability makes GasTDL-3100 a perfect choice for critical applications in steel manufacturing.
