SFFR Burner (low emission)
The SFFR flat-flame burner is vertically mounted and vertically
wall-fired. The SFFR burner takes the next step in stage fuel combustion
utilizing an internal, controlled flue gas recirculation system
that intimately mixes the primary fuel with inducted flue gas. This
process is separated from the combustion air source, allowing the
fuel and flue gas to thoroughly mix, and producing a fuel mixture
with a lower flame temperature. A key advantage to
the SFFR burner over conventionally deeply fuel staged low-NOx burners
is the SFFR's use of more primary fuel gas to create higher exit
momentum of the fuel injecting into the air stream. The benefits
are stiffer flames that adhere to the wall and a burner that uses
less staged fuel to achieve low emission levels. Because of the
reduced amount of staged fuel, the SFFR burner is less susceptible
to flame interaction between burners and flame rollover into the
process tubes.

LPMF Burner (ultra-low emssion)
[Patented]
The LPMF burner is a lean premix, flat-flame burner suitable for
high-temperature applications that require industry-leading, low
emission levels. The LPMF burner is a culmination of past and
present technology to meet the most challenging applications. The LPMF burner
originates from premix, staged fuel and INFURNOx™ technology.
First, the LPMF burner employs venturi to inspirate 100% of the
airflow required via the primary fuel jets. A fraction of the fuel
is then mixed with all of the combustion air, creating a lean but
combustible mixture. The air-fuel mixture exits the venturi assemblies
with a high momentum, creating a primary combustion zone that is
stiff and stable. Next, the secondary fuel is injected into the
combustion zone. With tile geometry enhancements, the stage fuel
is delayed from entering the combustion zone, allowing the stage
fuel to mix with furnace flue gases. The inerted fuel gas is then
introduced into the air stream allowing for complete combustion. The LPMF burner achieves a stiff
flame, which is necessary to prevent flame-to-flame interaction
and flame rollover. When compared to conventional low-NOx burners,
the LPMF burner gains a superior advantage in producing ultra-low
emission levels. With a modular design that allows it to be configured
specifically to your application, the LPMF burner can be installed
through the wall or floor of a furnace, and is well suited for retrofits
or new installations.
Radiant Wall Burners
The PMS burner is a premix radiant-wall burner utilized in ethylene
and reforming applications. The PMS burner uses proven technology
designed specifically to provide a radial flame that lies flat against
the fired wall of a furnace. The combustion process provides a uniform
temperature to the fired wall, allowing for even heat flux distribution
to the process coils in the radiant section of a fired heater.

LMPW Burner (ultra-low emission)
[Patented]
The LPMW burner is a lean premix radiant-wall burner for ethylene
cracking and reformer furnaces. Building
on the successful design of the PMS series of burners, the LPMW
burner utilizes technology that allows for 100% of the combustion
air to be inspirated with a fraction of the fuel through the venturi.
The balance of the fuel is then staged to achieve ultra-low emission
levels. The LPMW burner technology is excellent for retrofits of
existing furnaces as well as new installations.

SMR-18 Burner (low emission)
The SMR burner is a round-flame burner specifically designed
for ethylene applications. The SMR burner is ideal for applications
requiring a round flame and utilizes deep fuel staging to entrain
flue gases and lower emissions levels compared to conventional
fuel-staged burners. The burner's primary fuel jets are fired
through a tunnel to inject flue gas into the primary combustion
zone. The SMR burner can be employed as either a freestanding
flame or wall-fired flame.
Large Scale Vortex LSV™ Burner
The patented LSV burner technology, licensed from Air Products
and Chemicals, Inc. by John Zink for steam methane reforming applications,
is designed with a proprietary fluidic flame stabilizer and fuel
injectors. The innovative fluidic flame stabilizer requires
little fuel in the primary flame zone. The result? Lower peak flame
temperatures provide a substantial reduction in NOx emissions. The
proprietary injectors enhanced furnace gas entrainment minimizing
NOx from the secondary fuel.
The LSV burner is available for process heating applications
employing
various air supply modes (natural, induced, or forced, ambient or
preheat), fuel compositions (Natural gas and refinery fuels), and common burner
firing configurations.
