Great Southern Flameless, LLC (“GSF”)

Great Southern Flameless, LLC, established November 1, 2005, is dedicated to providing the most advanced solutions to meet your fired heater process and emissions
goals. Great Southern Flameless now offers a conventional process heater design that can also be operated in the flameless mode for extreme NOx reduction (3-8 ppm) without an SCR.  Also, the Great Southern Flameless heater improves efficiency (91% - LHV), increases run lengths, reduces fuel consumption; and decreases CO2 green house gases by 10-20%.  Great Southern Flameless now has 2 pending patents on this innovative technology.

Flameless combustion technology (also referred to as HITAC or high temperature air combustion) is not a new technology.  Applying this technology to direct fired refinery heaters is new and presents certain unique design challenges.  Most other flameless combustion applications for heat transfer have been associated with the higher temperature processes of the steel and glass industry.  Great Southern Flameless has developed new innovative technology that creates flameless combustion at flux rates and bridgewall temperatures common to refinery process heaters.  This new technology also meets our industry’s stringent requirements for safety, reliability, operability, and maintainability.  Great Southern Flameless technology permits a wide range of operation (fuel type and turndown), a wide selection of heater types, and in addition makes it safe and easy to switch from conventional combustion to flameless and from flameless combustion to conventional. 

Great Southern Flameless technology can be retrofitted to existing heaters or we can design and fabricate new heaters that can be operated in the conventional mode or in the flameless mode.

Great Southern Flameless is dedicated to leading our industry to this next generation of fired heater.  We believe that flameless combustion for direct fired heaters will be common in the very near future.  Just as internal flue gas recirculation (Ultra-low NOx technology) rapidly advanced from introduction to the industry in 1989 to the preferred method of combustion by 1993, flameless combustion will rapidly prove its merits and become the preferred design for direct fired refinery heaters.
