When combustible gases are generated in the production unit and need to be discharged urgently, these gases are transported to the flare head of the Flare stack through a special discharge pipeline. At this time, the ignition system responds quickly, generates high-voltage electric sparks through a high-energy igniter or uses other advanced ignition methods, such as plasma ignition, to ignite the pilot light. The pilot light is in a constant burning state, providing a stable and reliable fire source for the subsequent combustion of combustible gases.
The flare tip usually adopts a special design structure, such as a multi-hole nozzle, a swirl device, etc., which can promote the full mixing and uniform distribution of the combustible gas and air. Inside the flare tip, the mixture of combustible gas and air reacts rapidly under the ignition of the pilot lamp to produce a high-temperature flame. Under the guidance of the flare barrel, the flame produced by the combustion is discharged upward at a specific angle and speed to ensure that the combustion products can be safely diffused into the atmosphere. The control system monitors and accurately controls the entire elevated flare system in real time. It collects parameters such as the flow rate, pressure, and temperature of the combustible gas, as well as the flame state of the flare tip, the combustion condition of the pilot lamp, and the temperature of the flare barrel through various sensors. Based on these monitoring data, the control system automatically adjusts the flow rate of the combustible gas, the working state of the ignition system, the combustion intensity of the pilot lamp, etc., to ensure that the elevated flare can operate safely, efficiently, and stably under various working conditions.

1. Strong processing capacity The flare stack usually has a large processing capacity and can handle a large amount of combustible gas emissions. Its design can adapt to the needs of high-flow and high-pressure gas emissions, and is suitable for emergency emissions and waste gas treatment of large industrial production equipment.
2. Obvious height advantage Due to its towering structure, the flare stack can lift the flames and heat radiation generated by combustion to a higher altitude, reducing the impact on the surrounding environment and personnel. At the same time, the higher emission height is also conducive to the diffusion of combustion products and reduces the impact on ground air quality.
3. High visibility The flare stack can be seen from a distance and has high visibility. This enables operators and surrounding personnel to understand the operating status of the flare stack in a timely manner so that they can quickly take countermeasures when abnormal situations occur.
4. Reliable ignition system The flare stack is equipped with an advanced ignition system that can ensure that the combustible gas is ignited quickly and reliably under various working conditions. The ignition system usually has two modes: automatic ignition and manual ignition to meet different operating needs.
5. Advanced control system It has an advanced control system that can monitor the operating parameters of the flare stack in real time, such as gas flow, pressure, temperature, flame status, etc. The control system can automatically adjust the operating status of the flare stack according to the monitoring data to ensure the safe and stable operation of the flare stack.
6. Relatively convenient maintenance Although the flare stack is high, it is usually designed with structures and passages that are easy to maintain. Maintenance personnel can perform daily maintenance and overhaul of the flare stack through dedicated maintenance platforms and ladders and other facilities.
