The document describes Technip's Large Scale Vortex (LSVTM) burner technology. It provides low NOx emissions and reliable combustion while meeting demands for increased capacity, efficiency, and emissions regulations. The LSVTM burner was developed by Air Products and has been in successful operation for 10 years. It features unique nozzle design and flexible flame stabilization to enable lean, cool combustion and uniform heat release. This results in ultra-low NOx and increased equipment lifetime. The LSVTM burner can be used across various process applications and configurations.

Developing combustion solutions
for tomorrow
Users as well as regulators are placing greater expectations and demands on burners than at any time in the past. On the
one hand Plant owners want larger CAPACITY, greater RELIABILIY and of course lower COST. One the other hand there is
mounting pressure from authorities in the form of higher efficiency and tighter emission limits on pollutants such as CO
and NOx.
Technip’s experts in fired heater technology are engaged in developing firing systems to suit the changing market
conditions. We are proud to present our Large Scale Vortex (LSV™)
burner technology.
The LSV™ burner technology was developed by Air Products, an operating
company with long experience in fired heater operation. The LSV™ burner
has already been in service for 10 years in steam reformer installations
owned and operated by Air Products.
These features results in optimum performance of the furnace. Further,
the LSV™ burner can be used to avoid expensive SCR/DeNOx systems in
certain applications and regions.

The LSV™ burner can be applied for different process heating applications and
combustion air supply modes (natural draft, induced draft or forced draft). The
combustion air may be at ambient temperature or preheated. Moreover the LSV™
burner is suitable for a wide range of fuel gas compositions and firing configurations.
The LSV™ burner can be placed on the roof (top firing) or on the floor (bottom
firing) of a firebox.
Field results support our claim to best-in-class Low NOx Burner technology:
Ultra low NOx emissions
Uniform flame heat release profile
Compact flame
Increased radiant tubes’ lifetime
Trouble-free operating in plant
SCR (Selective Catalytic Reduction) avoidance in certain applications
Smooth burner light-off
LSV™ burners can also be applied in retrofit projects. Replacement of existing
burners with LSVs™ offers the additional possibility to increase capacity and run
length.
The quality of the LSV™ burner lies in its:
Simple, single burner block design
High grade tip materials as standard
Robust design
Shielding of the fuel staging tips from radiation to avoid overheating and
tip-fouling
Its versatility for revamp projects

The LSV™ burner is a cost effective low
NOx combustion solution that is an
outcome of Technip’s track record in
design.

Technip continuously researches the performance of
the LSV™ burner in a radiant firebox environment, such
as an ethylene furnace or a steam reformer. We apply
our proprietary CFD-NOx simulator to correctly
predict flame shape, the flue gas temperature and
flow profiles and the radiant coil heat flux profiles.
The Clean Energy Lab (CEL) at Air Products
headquarters in Allentown PA, (USA) has been set up
to fine tune the LSV™ burner concept to achieve even
lower emissions.
LSV™ technology has been successfully applied over
the last 10 years in furnaces and hydrogen
installations worldwide.
Multiple LSV™ burners have been installed in new and
revamp projects in the USA, Sweden, Saudi Arabia,
The Netherlands and Malaysia, on both induced draft
and balanced draft furnaces. They are operating to the
full satisfaction of their customers with very limited
maintenance effort.
