Key Parameter Examples |
| Petrochemical/Refinery (Elevated Flare) |
Process exhaust gas (multicomponent gas) |
Heat load: Dozens to hundreds of MW; Flare tip diameter: 0.8m - several meters (increasing with treatment capacity); Flame length: Dozens of meters (e.g., about 45m at 200 t/h emission). |
| Metallurgical Industry (BF Gas Flaring) |
Blast furnace gas (dust-laden, high temperature) |
Flare tip material: 316L heat-resistant steel (swirl plate), 304 heat-resistant steel (outer shell); Temperature resistance: Long-term >1000ºC; Backfire prevention design: Dynamic sealing flame arrester, labyrinth molecular seal. |
| Environmental Protection (Landfill/Farm Biogas) |
Biogas (containing methane, tar) |
Heat load: Adapted to biogas production (e.g., several kW for small farm biogas flares, up to several MW for large landfills); Burner head structure: Anti-coking design (porous flame stabilizer, air bag nozzle for uniform gas distribution); Control: Interlocked with biogas collection system, pressure-triggered automatic ignition (start at medium pressure, stop at low pressure). |
When a combustible gas emission signal is received, the control system starts the ignition program. First, a high-voltage electric spark is generated by a high-energy igniter to ignite the pilot lamp, which remains burning to provide a stable fire source for the subsequent combustion of the combustible gas.
The combustible gas is transported to the burner group of the ground torch through a pipeline. The burner group usually adopts a special structural design, such as a porous nozzle, a swirl device, etc., to achieve full mixing and uniform distribution of the combustible gas and air. Inside the burner, the mixture of combustible gas and air burns rapidly under the ignition of the pilot lamp, generating a high-temperature flame.
The windproof and soundproof wall surrounds the burner group. On the one hand, it plays a windproof role to prevent external wind from interfering with the flame and ensure the stability and reliability of combustion; on the other hand, it reduces the noise generated during the combustion process through special sound-absorbing materials and structural design.
The control system monitors and controls the entire ground flare system in real time. It monitors the flow, pressure, temperature and other parameters of the combustible gas, as well as the flame state of the burner, the temperature of the windproof and soundproof wall, etc. According to the monitoring results, the control system automatically adjusts the flow of combustible gas, the working state of the ignition system, etc., to ensure that the ground flare can operate safely and efficiently under various working conditions.
Auxiliary systems include nitrogen purge system, steam fire extinguishing system, etc. The nitrogen purge system purges the pipeline and burner before starting and after stopping the ground flare to prevent residual combustible gas and flashback. In emergency situations, such as uncontrolled combustion, the steam fire extinguishing system can extinguish the flame by spraying steam to ensure the safety of the system.
1. Excellent safety
The ground flares is equipped with advanced safety systems, including flame monitoring devices, automatic ignition systems and emergency stop systems. The flame monitoring device can monitor the flame status in real time. Once an abnormality is found, it will immediately sound an alarm and take corresponding measures. The automatic ignition system ensures that the combustible gas can be ignited quickly and reliably when needed, which improves the startup speed and stability of the system. The emergency stop system quickly cuts off the supply of combustible gas in an emergency, stops the combustion process, and ensures the safety of personnel and equipment.
In addition, the ground torch also has a good windproof design, which can effectively resist the interference of external wind on the flame and ensure the stability of combustion. At the same time, professional anti-backfire equipment can prevent the flame from flowing back into the pipeline system, further improving the safety of the system.
2. Excellent environmental performance
The ground torch adopts advanced combustion technology, which can make the combustible gas fully burn, reduce the emission of incomplete combustion products, and reduce pollution to the environment. The special silencer design can effectively reduce the noise generated during the combustion process and reduce the noise pollution to the surrounding environment. Reasonable layout and design also make the ground torch have less impact on the thermal radiation of the surrounding environment, ensuring the safety of surrounding personnel and equipment.
3. High operational flexibility
The ground flare has a wide load adjustment range and can adapt to the combustible gas emission requirements of different flow rates and pressures. The advanced automatic control system realizes remote monitoring and operation, which is convenient for users to grasp the system operation status at any time and adjust it according to the actual situation. In an emergency, the ground flare can start quickly and deal with the combustible gas emission in time to ensure production safety.
4. Compact design and high land utilization rate
The ground flare usually adopts a compact structural design with a small footprint. Compared with the elevated flare, it is more suitable for use in areas with tight land resources. At the same time, the ground flare can be reasonably laid out and integrated with other facilities in the factory to further improve land utilization.
5. Convenient maintenance and long life
The equipment and components of the ground flare are relatively easy to access, which is convenient for daily maintenance and overhaul work. High-quality materials and advanced manufacturing processes ensure that the ground flare has a long service life, reduces the frequency of equipment replacement, and reduces maintenance costs.
In short, the ground flare has become an ideal choice in the field of waste gas treatment with its excellent safety, outstanding environmental performance, high operational flexibility, compact design and convenient maintenance.
