Ground Flare

System Overview  

The ground flare is a concealed safety emission device used in petrochemical, oil, and gas storage and transportation sectors. It is specifically designed to handle high-pressure, flammable, explosive, or toxic waste gases, achieving harmless treatment through enclosed combustion. The system features low-visibility design, making it suitable for environmentally sensitive areas or space-constrained sites. It offers rapid response, low noise, and high-efficiency combustion.  

Core Components  

- Burner Array: Modular multi-nozzle structure made of high-temperature-resistant alloy, supporting staged combustion.  

- Enclosed Combustion Chamber: Insulation modules + carbon steel/stainless steel shell, withstanding temperatures ≥1200°C, preventing heat radiation leakage.  

- Premix Device: Gas/air premix technology to enhance combustion stability and reduce black smoke generation.  

- Ignition System: High-energy electronic ignition + flame monitoring, explosion-proof rating ExdⅡBT4, suitable for humid environments.  

- Control System: SIS safety instrumented system, integrated with pressure/temperature/gas concentration interlock, enabling automatic start-stop.  

- Structural Protection: Explosion-proof wall + pit-type layout, equipped with water curtain cooling/steam inerting systems.  

Technical Advantages  

- Efficient and Concealed: Single-unit processing capacity of 1,000-200,000 Nm³/h, combustion efficiency ≥99%, with no visible flame.  

- Safe and Explosion-Proof: Dual protection with negative pressure combustion chamber + flame arrester.  

- Environmentally Friendly and Low Disturbance: Flue gas emissions meet standards.  

- Compact and Durable: Reduces footprint by 40%, lifespan ≥15 years, and adapts to environments ranging from -40℃ to 60℃.  

Application Scenarios  

- Refining and Chemical Parks: Emergency vent gas treatment for ethylene units and reforming units.  

- Fine Chemicals: Safe disposal of highly toxic/odorous gases (e.g., H2S, VOCs).  

- Oil and Gas Field Gathering and Transportation: High-pressure venting of natural gas, shale gas wellhead overpressure discharge.  

- Storage and Transportation Facilities: LPG/LNG storage tanks, pipeline pressure relief protection.  

The ground flare system, with its low visibility, high safety redundancy, and modular deployment advantages, has become the preferred emission solution for environmentally sensitive areas and high-density industrial parks. It helps enterprises achieve clean production and ecological protection synergistically.
