What is FFG ignition?
Flame Front Generators are a traditional method of lighting flare pilots. An FFG panel mixes plant air and fuel gas into an ignition chamber. A spark plug ignites the mixture. The ‘flame front’ travels through a 1′ pipe to flare pilot.
How does a flame front generator work?
During operation the flow of fuel gas is established through the system and the flame front line is first purged, and then filled with the gas / air mix. The mix in the combustion chamber is ignited and the flame front initiated. The flame front ‘fire ball’ travels to the pilot tip where it ignites the pilot.
What is high energy ignition system?
High energy ignition, also known as H.E.I., is an electronic ignition system designed by the Delco-Remy Division of General Motors. It was used on all GM vehicles, at least in the North American market, from 1975 through the mid-1980s.
How is flare ignited?
The launcher uses compressed air to drive a pellet through the guide tube up to the flare tip/deck. Once the pellet exits the guide tube, the fuse is released and the pellet explodes producing a shower of sparks over the flare tip and any associated pilot burners thereby lighting the gas.
What is flare pilot?
The pilot burner is essentially a robust premixed burner unit designed to provide a stable flame for igniting the waste gas exiting the flare tip and features three main components, the venturi or mixer, gas jet or orifice and the burner nozzle.
What is flare pilot gas?
Pilot gas means gas introduced into a flare tip that provides a flame to ignite the flare vent gas.
What is flame front?
The leading edge of a flame propagating through a gaseous mixture or across the surface of a solid or liquid.
What is the difference between HEI and points?
Since an HEI system produces more voltage and amperage output than a points-style distributor, a larger-diameter distributor cap is needed to prevent voltage from cross-firing inside the cap. If you’re thinking about an upgrade, make sure your vehicle has enough clearance between the engine and firewall.
What is flare ignition system?
A flame front generator is a system in which a gas/air mixture is introduced at ground level and flows up a one-inch line to the pilot burner. After filling this line with the mixture it is ignited by a spark. The resulting flame travels to the top of the flare where the pilot burner is ignited.
What is flare line?
• A Flare System is an arrangement of piping and specialised equipment that. collects hydrocarbon releases from relief valves, blowdown valves, pressure. control valves and manual vents and disposes of them by combustion at a. remote and safe location.
Why do you need a pilot burner?
The main function of a pilot burner is to ignite the main burner nozzle that went off. The other function is to keep the burner chamber safe from accumulating explosive gases.
What is purge gas in flare?
Flare purge gas means gas introduced between a flare header’s water seal and the flare tip to prevent oxygen infiltration (backflow) into the flare tip. For a flare with no water seal, the function of flare purge gas is performed by flare sweep gas.
What is the maximum speed of fire?
Maximum speeds for wildfires are estimated to be approximately ten miles per hour.
What is the flame speed of LPG?
Increasing initial pressure range (1-3 bar), stretched laminar flame speed of LPG-air mixture decreases from (2.2-1.5 m/s) and laminar burning velocity also decreases from (31-20 cm/s).
How a Distributorless engine works?
In a distributorless ignition system, a discrete coil provides voltage to each spark plug. Your car’s computer can then determine the precise moment to ignite each cylinder. In addition to providing greater control, this system also removes all moving mechanical components.
