Fixed Multi GAS DETECTION SYSTEMS FOR STEEL PLANTS | SAFETY FROM INVISIBLE HAZARDS

Steel plants operate with high temperatures, combustible gases and toxic gases such as Carbon Monoxide (CO), Oxygen, CO2, Ammonia, Hydrogen (H₂), Methane (CH₄), Hydrogen Sulphide (H₂S), PNG and other process gases. Continuous gas monitoring helps identify hazardous concentrations at an early stage and supports timely alarms, ventilation and emergency response.

🔹 Typical Gas Detection Application Areas:

1. Coke Oven & Coke Handling Areas
• CO, CH₄, H₂S and combustible gas monitoring
• Coke oven gas leakage detection

2. Blast Furnace Area
• CO monitoring around furnace and gas lines
• Blast Furnace Gas (BFG) leakage detection
• Operator/workplace safety monitoring

3. BOF / Converter Area
• CO monitoring around converter gas systems
• Gas leakage detection in process areas

4. EAF / Electric Arc Furnace Area
• CO and combustible gas monitoring
• Process and workplace safety

5. Gas Cleaning & Gas Distribution Systems
• BFG / COG / LDG leakage monitoring
• Gas pipeline, valve and manifold areas

6. Rolling Mill & Reheating Furnace
• Natural Gas / CH₄ leakage detection
• CO monitoring where combustion processes are present

7. Oxygen Plant & Gas Storage Areas
• O₂ concentration monitoring
• Oxygen enrichment/deficiency monitoring where applicable

8. Hydrogen / Utility Areas
• H₂ leakage detection
• Hydrogen generation, storage and distribution areas

9. Chemical / Water Treatment & STP Areas
• H₂S, NH₃, Cl₂ and other application-specific toxic gas monitoring

10. Electrical / UPS & Battery Rooms
• H₂ monitoring during battery charging
• Ventilation/control integration

⚙️ From Detection to Action

Gas Detector → Gas Concentration Monitoring → Alarm → PLC/Control Panel → Ventilation / Exhaust Fan / Interlock → BMS Integration

With suitable system design, gas detection can be integrated with PLC/control panels, ventilation systems, alarms, emergency shutdowns and BMS/SCADA according to the plant’s safety philosophy.
