Zeeco’s AF flare series uses advanced technology proven to achieve smokeless flaring when neither steam nor assist gas is available or economical. Our AF flares utilize a low-pressure blower to inject assist air via Zeeco’s proprietary design, which splits the waste gas stream into several smaller streams at the exit of the flare tip. This increases the contact surface area between the waste gas and the assist air, maximizing mixing and turbulence while minimizing the amount of blower horsepower required to achieve smokeless flaring.
Better design means safer operation.
The waste gases from the flare header as well as the assist air from the blower are isolated from the base of the flare stack to the top of the flare tip. As a result, the two streams never come in contact with each other prior to exiting the flare tip. This ensures the safe operation of your flare system. Zeeco’s AF flare systems can operate without the blower, providing safe disposal of the waste gas in the event of a power outage. Our proprietary design and the blower’s velocity virtually eliminate “flame lick” on the exterior of the flare tip and “burnback” inside the flare tip. The forced air from the blower also shortens the flame length and reduces the radiation at grade due to the highly aerated mixture of waste gases.
Applications
- ZEECO® AF series flares are ideal for refining, LNG, production, steel
industries, petrochemical, offshore platforms, pulp and paper plants, pharmaceuticals, and food processing plants. - Our AF series flares are the preferred choice for industries that require smokeless flaring when neither steam nor assist gas is desired, available, or cost-effective.
- AF series flares are the best option for harsh conditions, such as arctic environments where steam could freeze or desert environments where water is scarce.
- ZEECO AF series flare tips make sense as a replacement for other
manufacturers’ flare tips.
