How Gas Flare Ignition System Works And How It Affects Health And Environment

People with knowledge about flare know it very well that ignition systems are the most important part of the flare design. Earlier, it was tough to relight the flare in a system. The flare pilot ignition systems have been introduced to make this task easy.

With the increase in the number of facilities employing flare gas recovery systems, there is an increased pressure on the dependability of the flare pilot ignition systems. There is a greater pressure to make these systems efficient so they take care of the safety during an unfortunate occurrence such as a blow down, plant upset, or an emergency shutdown.

You can opt for manual or automatic flare ignition systems, to add additional support to your existing equipment. You can also opt for pilot burners and flame monitoring equipment to maximize the reliability of the system.

Here are some of the most common flare ignition systems used in different plants:

Flame Front Generator: This system channels the compressed air and fuel gas through control valves. These valves direct them to a mixing chamber which has an ignition device. A flame front line is connected to the pilot burner nozzle and the gas/air mix is ignited and the flame front is generated.

Electronic Ignition: This is simple and very easy to automate and frequently preferred. There system has two basic forms – high energy (HE) and high tension (HT). In this, the pilot flame monitoring can be achieved through thermocouples.

Ballistic Pellet Ignition: These systems have a launching cabinet which containing ignition pellets, a pellet collector and a guide tube. The launcher drives pellets using compressed air. After exciting the guide tube, the pellet explodes and produces a shower of sparks and thus light the gas.

Ignition systems channel the waste air/gas from spreading into the surroundings. They are a great way to provide safety and security to the environment around, and thus help in complying with health and environmental regulations.
