Applications
Forney duct burners are used in various applications including:
• Cogeneration and Combined Cycle - Increase steam generation and plant power output.
• Fresh Air Firing - Used as a backup source of hot gas to HRSG/WHRU when combustion turbine is off-line.
• Air Heaters - Heat a large volume of air with minimal pressure drop.
• Process Heating - Many different process streams can be heated, including but not limited to SCR Reheat
applications, Ammonia/Urea Vaporizers and CFB inlet air heaters.
Operating Conditions
Forney duct burners offer customized solutions with flexible operating conditions.
Heat Input: 10 - 1,100 MMBtu/hr, LHV
Inlet Exhaust Gas Flow: 30,000 - 5,750,000 lbs/hr
Inlet Exhaust Gas Temperature: up to 1,250°F
Depending on specific emission requirements, augmenting air may be required when inlet oxygen levels and/or turbine
exhaust gas (TEG) temperatures are very low. Even temperature distribution is key to system performance and is
highly influenced by the uniformity of the combustion air / TEG velocity profile. Typical exhaust gas distribution to the
duct burner should be a minimum of ±20% of the average velocity over 90% of the duct cross section.
