Cubic Instruments In-Situ Laser Process Gas Analyzer for Coke Ovens Safety Monitoring
Coke is an essential material in steel production, serving as a source of thermal energy. It is manufactured from heating coal in the oxygen-deficient environment of the coke ovens. During this process, significant amounts of syngas including H2, CH4, CO etc is generated and the combustible component accounts for about 90%. The lower explosive limit of syngas, the higher the risk of an explosion when oxygen levels reach a certain point. According to Safety Data Sheet by United States Steel, the explosion limit of syngas within coke oven falls in the range of 4% to 75%. Consequently, it’s imperative for operators to utilize an oxygen gas analyzer to continuously monitor the oxygen content within the gas stream, ensuring it is maintained at a near zero level (normally below 2%) to prevent a potential explosion. In the scope of safety monitoring during steel production, oxygen gas analyzer is demanded to meet two essential requirements: rapid response times to promptly execute protective measures when facing potential explosion risks, and exceptional accuracy to avoid any false alarms that might disrupt the normal production processes.
To address this critical need in the steel industry, Cubic Instruments has developed the in-situ laser process gas analyzer GasTDL-3100. Based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology, GasTDL-3100 is designed for real-time oxygen concentration measurement under harsh conditions of high temperatures, high dust loads and high humidity in coke oven.
Due to optical measuring principle of TDLAS and design of in-situ installation without sampling or conditioning, GasTDL-3100 features fast response time of less than 4 seconds, allowing operators to react promptly to unforeseen circumstances. GasTDL-3100 stands out for its high selectivity of oxygen gas, ensuring it operates without cross-interference from background gases during manufacturing processes in coke ovens . Additionally, it demonstrates reliable and accurate performance with high precision of ±1% F.S. oxygen gas measurement, ensuring operators to precisely maintain oxygen concentrations within safe limits. In addition to its core performances, GasTDL-3100 also boasts explosion-proof capabilities with Exd II CT6 certification, making it an ideal choice for operating under the harsh conditions of coke ovens. The design of no moving parts eliminates extra maintenance costs and guarantees a long lifetime. All these features make GasTDL-3100 an excellent solution for safety monitoring in coke oven applications.
The remarkable features of GasTDL-3100:
- Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology.
- Fast response, T90≤4s.
- High precision within a deviation of less than ±1% F.S.
- Low maintenance and operating costs.
With the advantages of fast response, high accuracy, and convenient in-situ installation, GasTDL-3100 is an ideal choice for coke oven safety monitoring. For more product information, please click on https://www.gas-analyzers.com/ProcessGasAnalyzer/info52/ or contact us!
