Explosion-Proof Ground Flare for Oil & Gas Field Venting

Product Description

 

Product Introduction

Our biogas flares are specially designed for the safe incineration and treatment of combustible gases such as biogas, landfill gas, livestock farm biogas, and industrial organic waste gas. The product line is divided into two main series: enclosed biogas flares and open biogas flares. With a modular skid-mounted structure, the equipment integrates an efficient combustion system, intelligent ignition control, wind resistance devices, and safety interlock systems. It can achieve harmless and zero-emission treatment of biogas, avoiding safety and environmental risks caused by direct methane emission. Widely applied in biogas collection and utilization projects, landfills, livestock farms, sewage treatment plants and other scenarios.

7. Corrosion Resistance & Long Service Life: The main body is made of 304/316L stainless steel, adapting to corrosive media such as in biogas, with long service life and low maintenance costs
8. Intelligent Remote Monitoring: Support 4G/5G/GPRS remote data transmission, real-time monitoring of temperature, pressure, flow, and realizing remote start/stop and fault early warning

 

Working Principle

 

 

 

 

The core of the biogas flare is controlled high-temperature combustion technology. Through the four-step process of "gas intake control → precise ignition → high-temperature combustion → safe emission", it realizes harmless treatment of biogas. The specific process is as follows
1. Gas Intake Control: Biogas enters the combustion system through pressure stabilizing valve and flame arrester, and the intake pressure and flow are automatically adjusted according to the biogas volume to avoid overpressure risks
2. Precise Ignition: The system automatically triggers the electronic/automatic ignition device according to the biogas concentration and working conditions, and high-energy sparks ignite the biogas instantly

3. High-temperature Combustion: Biogas undergoes sufficient oxidative decomposition in the high-temperature combustion zone of 850-1100ºC, combustible substances such as methane are converted into CO2 and H2O, and toxic and harmful substances such as dioxins are decomposed simultaneously
4. Safe Emission: The high-temperature flue gas after combustion is discharged up to the standard through the chimney. Enclosed biogas flares are also equipped with sound absorption and heat insulation structures to reduce noise and thermal radiation. The whole process is intelligently monitored by PLC to ensure safe and stable operation

 
 

Application Scenarios

1. Livestock Farm Scenarios: Biogas collection and treatment from livestock and poultry manure in large-scale pig farms, cattle farms, chicken farms, etc., realizing resource utilization of manure
2. Landfill Scenarios: Safe incineration of landfill gas in municipal solid waste landfills and industrial waste landfills, avoiding methane escape and environmental pollution
3. Sewage Treatment Plant Scenarios: Biogas treatment from anaerobic digestion of industrial sewage and municipal sewage, supporting biogas power generation or direct incineration

4. Industrial Organic Waste Gas Scenarios: Collaborative incineration of low-concentration organic waste gas from chemical, pharmaceutical, food processing and other industries, realizing standard treatment of waste gas
5. Biogas Purification Project Scenarios: Safe vent incineration of excess biogas during biogas purification to ensure the safe operation of the system
6. Other Scenarios: Combustible gas treatment needs in rural biogas centralized supply stations, garbage leachate treatment stations, biomass fermentation projects, etc.
