Tornado - Pilot & Ignition Systems
From Flare Systems
Simply put – a pilot is continuous, it’s always on. The pilot flame serves to light the waste gas stream exiting the flare, or inside an incinerator, or any other combustion unit. You need to have an available fuel gas supply in order to install a continuous pilot. An ignitor (or ignition system) is an intermittent spark or flame front that is responsible for keeping the pilot lit. On systems where there is no on site fuel supply available, and therefore no pilot, the ignitor may be used to light the waste gas stream directly.

Products Details
Tornado recommends one of four sources of ignition in conjunction with its flare systems:
Standing Pilot
Tornado pilots are made from Silica Carbide. They are wind-proof up to 200 mph, fuel-efficient, and resistant to the most corrosive conditions. Tornado pilots offer the following benefits over competitive units:
- Low fuel consumption 25 SCFH
- Short intense blue flame
- Tested to wind speeds of 200mph
- Suitable for H2S
In Alberta, as per AER Directive 060, if a waste gas stream being flared has more than 1% H2S then a standing pilot or electronic sparking ignition system is required (excluding gas plants)
The TPMR system operates a continuous standing pilot made of silica carbide. An enclosed thermocouple sits within the nozzle monitoring its temperature to detect flame failure. Should the pilot flame go out, the TPMR will activate an auto-relight process by opening a solenoid valve and igniting a stoichiometric fuel-air mixture. This sends a flame front to relight the pilot and the flare remains fully functional. If the system encounters a problem it cannot correct itself, the Tornado unit initiates an auto-shutdown to close the fuel gas supply to the pilot and activates an alarm.
In Alberta as per AER Directive 060, a standing pilot with automatic ignition is required for gas plants flaring waste gas streams with greater than 0.001% H2S
Electronic Ignition SystemThe Tornado Electronic Ignition System (TEIS) is used in low flow, high heat value and high flammability gas streams. It is designed to arc every 30 to 45 seconds to directly light the waste gas stream where no fuel gas supply (therefore no continuous pilot) is available.
In Alberta, as per AER Directive 060, if a waste gas stream being flared has more than 1% H2S then a standing pilot or electronic sparking ignition system is required (excluding gas plants)
Manual Ignition Tube SystemA Tornado torpedo tube is a manual ignition system used to ignite both standing pilots (as used on a TPMR system) or for igniting a flare via a shot tube running the length of the flare. The most rudimentary of all systems, the torpedo tube carries a shot from a flare gun to the top of a flare stack to ignite the waste gas stream. These systems are not recommended for stacks over 100-feet tall.
Tornado standing pilots and TEIS ignition systems can be mounted on the side of a flare stack retractably. This enables any maintenance operation to these pilot systems to be done easily from the ground, without the need for cranes or ladders to remove them from the flare’s tip.
Is your flare unreliable? Tornado has helped many customers replace (or retrofit) a poorly performing ignition package off any flare stack with one of our superior units. Entire tracking packages can be easily mounted onto an existing flare to improve performance with a more reliable pilot and ignition system supplied by Tornado Technologies Inc.
