Ammonia
Reformer Burners |

Lanemark HC
gas fired, round flame burners provide
the process heat for down fired
steam reforming, to initiate the
reaction which ‘reforms’ the reformer
feed stock – typically natural gas
or naphtha resulting in ammonia
/ urea which is used in the production
of fertiliser.
The burners’ stable, tightly controlled
flame profile allows high calorific
value fuels such as natural gas
and refinery gas to be fired either
on their own or in combination with
by-product gases known as purge
gas, off gas or tail gas which contain
methane and moderate to high levels
of nitrogen. Low NOx, CO and noise
emissions together with high levels
of turndown and flexibility ensure
burner stability across the full
operating range.
Burners can also be configured in
vertical upward firing or horizontal
firing arrangements. This enables
burners to be mounted on the radiant
section flue gas exit tunnels (tunnel
burners) or between the radiant
section and the convection section
for adding heat to superheat process
steam (Steam Super Heating (SSH)
burners). High combustion air temperatures
and varying furnace pressure conditions
can be accommodated within the burner
design.
Burner ignition can be by portable
spark ignitor, portable pilot or
if the client’s start up philosophy
requires, then by a fixed manual
or automatic pilot.
A single Lanemark ‘Thermimax Matrix’
head can accommodate both high and
low calorific fuel gases either
as single fuels or combined/mixed
units upstream of the burner in
any available proportion.
The Lanemark ‘Thermimax Matrix’
burner head produces both fuel rich
and fuel lean zones resulting in
low NOx emissions without impacting
on turndown, stability or CO emissions.
Low noise emissions result from
low to medium combustion air pressure
drops the intimate mixing properties
of the matrix design – avoiding
the need for external acoustic insulation
materials.
Flame lengths of less than 3 m with
diameters of under 0.7 m, low excess
air operation at design/ normal
burner loads and high excess air
at low load, start up and warm standby
conditions all mean that specific
site requirements can be met by
Lanemark burners. |

Ethylene
Cracking Burners |

|
 |
Lanemark
KS burners provide the process heat
for Ethylene Cracking Furnaces with
side fired, horizontally mounted
burners (Radiant Wall or Vertical
Flat Flame type) combined with floor
mounted, vertically up fired burners
(Round or Flat Flame).
The burners’ stable, tightly controlled
flame profile allows a wide range
of typically high calorific value
fuel gases such as natural gas and
refinery fuel gas to be fired either
on their own or in combination.
Low NOx, CO and noise emissions
together with high levels of turndown
and flexibility ensure burner stability
across the full operating range.
Burner models include configurations
for the combustion air to be supplied
to the burner in natural draft,
induced draft or forced draft modes
all at low excess air operation.
In forced draft mode the combustion
air can be ambient, preheated or
may be supplied from a gas turbine
exhaust. Burners can include manual
ignition, with portable spark igniters
or portable pilot as well as with
fixed manual pilots, or can be supplied
as fully automatic pilot burners.
The burner tip design can accommodate
multiple fuel gases in either a
single fuel gas system where the
fuel gases are mixed upstream of
the burner in any combination or
as separate dual gas systems.
The KS burner range includes both
fuel staged and air staged designs
which result in low NOx emissions
without impacting on turndown, flame
stability or CO emissions. Low noise
emissions result from low to medium
combustion air pressure drops, the
mixing properties of the burner
tip and burner tile design, without
employing external acoustic insulation
materials.
Flame lengths and widths, which
can be tailored to suit the specific
furnace requirements, low excess
air operation at design/normal burner
loads and higher excess air, which
is typically present during start
up and warm standby conditions,
all combine to meet site requirements. |

Fired
Heater Burners |
| |
|
 |
Lanemark
KS Oil, Gas and Combined Oil & Gas
burners provide the process heat
for vertically up fired process
heaters (Round or Flat Flame).
The burners’ stable, tightly controlled
flame profile allows a wide range
of typically high calorific value
fuel gases – such as natural gas,
refinery fuel gas and light, medium
or heavy oils – to be fired either
on their own or in combination.
Waste fuel streams may also be introduced
to recover any calorific value they
may have. Low NOx, CO and noise
emissions together with high levels
of turndown and flexibility ensure
burner stability across the full
operating range.
Burner models include configurations
for the combustion air to be supplied
to the burner in natural draft,
induced draft or forced draft modes
– all at low excess air operation.
In forced draft mode the combustion
air can be ambient, preheated or
may be supplied from a gas turbine
exhaust. Burners can also incorporate
a fixed manual or fully automatic
pilot.
The burner design can accommodate
multiple fuel gases in either a
single fuel gas system, where the
fuel gases are mixed upstream of
the burner in any combination, or
as separate dual gas systems.
Fuel oil guns are available as steam
(heavy/medium oils) or air (light
oil) atomised with interlocked inlet
isolation valves. This ensures the
correct introduction sequence of
atomisation medium first, followed
by introduction of fuel oil. The
reverse burner shut off sequence
is also assured.
The KS burner range includes both
fuel staged and air staged burner
designs which result in low NOx
emissions without impacting on turndown,
flame stability or CO emissions.
Low noise emissions result from
low to medium combustion air pressure
drops, the mixing properties of
the burner tip, burner tile design
and internal acoustic insulation.
Flame lengths and widths can be
tailored to suit the specific furnace
requirements, low excess air operation
at design/normal burner loads and
higher excess air which is typically
present during start up and warm
standby conditions, all combine
to result in the furnace design
requirements being met. |

Hydrogen
Reformer Burners |
| |
|
 |
In
applications from crude oil refining
(desulphurisation) to the production
of technical and commercial gases,
Lanemark HC gas fired, round flame
burners provide the process heat
required to initiate the reaction
which ‘reforms’ the reformer feed
stock – typically natural gas or
naphtha - resulting in the production
of hydrogen.
The burners’ stable, tightly controlled
flame profile allows high calorific
value fuels such as natural gas
and refinery gas to be fired – either
on their own or in combination with
low calorific off gas from the process
Pressure Swing Absorption unit (PSA).
This process off gas is known as
PSA off gas, PSA purge gas or PSA
tail gas which typically contain
hydrogen, methane, carbon monoxide
and high levels of carbon dioxide.
The burners’ intimate mixing properties
ensure that permanent pilot burners
are not necessary and natural gas
or refinery fuel gas trim fuel flow
rates can be minimised thus saving
both operating cost and the use
of potential feed stock. Burner
ignition can be by portable spark
ignitor, portable pilot or, if the
client’s start up philosophy requires,
then by fixed pilot burners which
can be manual or automatic. Low
NOx, CO and noise emissions combine
with high levels of flexibility
to ensure burner stability in all
conditions.
Hydrogen reformer burners can be
supplied in induced draft or forced
draft mode. In forced draft mode
high combustion air temperatures
can be accommodated in the burner
design. This enables optimum waste
heat recovery combined with varying
excess air levels to be achieved,
thereby optimising process steam
generation from the reformer convection
section.
A single Lanemark ‘Thermimax Matrix’
head can accommodate both high and
low calorific fuel gases either
as single fuels or as combined/mixed
units upstream of the burners in
any available proportion. This means
only a single pipeline distribution
system to the penthouse, to each
burner row and to each individual
burner is required – helping to
minimise equipment, installation
and maintenance costs.
The Lanemark ‘Thermimax Matrix’
burner head produces both fuel rich
and fuel lean zones resulting in
low NOx emissions without impacting
on turndown, flame stability or
CO emissions. Low noise emissions
result from low to medium combustion
air pressure drop and the low fuel
gas pressure drop/intimate mixing
properties of the matrix design
– avoiding the need for external
burner acoustic insulation.
Flame lengths of less than 3 m with
diameters of under 0.7 m, low excess
air operation at design/ normal
burner loads and high excess air
at low load, start up, warm standby
and plant upset conditions all mean
that the Lanemark burners provide
a high level of flexibility, reliability
and availability. |

Methanol
Reformer Burners
|
| |
|
 |
Lanemark HC
gas fired, round flame burners provide
the process heat required to initiate
the reaction in down fired steam
reforming applications, which ‘reforms’
the reformer feed stock – typically
natural gas or naphtha – resulting
in the production of methanol.
The burners’ stable, tightly controlled
flame profile allows high calorific
value fuels such as natural gas
or refinery gas to be fired either
on their own or in combination with
purge gas, tail gas or synthesis
gas – which can contain high levels
of hydrogen and methane plus a significant
quantity of inerts such as carbon
dioxide and nitrogen. Low NOx, CO
and noise emissions combine with
high levels of flexibility to ensure
burner stability under all operating
conditions.
Auxiliary burners can also be provided,
typically mounted between the radiant
section and the convection section
of the furnace. These provide additional
heat to the flue gas after the radiant
section/before the convection section
to maintain process steam production
through the reformer catalyst life
cycle. Importantly, these burners
can be sized larger than the main
arch burners, reducing capital and
installation costs.
High combustion air temperatures
and varying furnace pressure conditions
can be accommodated within the burner
design while burner ignition can
be by portable spark ignitor, portable
pilot or, if the client’s start
up philosophy requires, then by
a fixed manual or automatic pilot.
A single Lanemark ‘Thermimax Matrix’
head can accommodate all fuel gases
that can be available for this application
either as single fuels or as combined/mixed
units upstream of the burners in
any available proportion.
The Lanemark ‘Thermimax Matrix’
burner head produces both fuel rich
and fuel lean zones resulting in
low NOx emissions without impacting
on turndown, stability or CO emissions.
Low noise emissions result from
low to medium combustion air pressure
drop and the intimate mixing properties
of the matrix design – avoiding
the need for external acoustic insulation.
Flame lengths of less than 3 m with
diameters of under 0.7 m, low excess
air operation at design/ normal
burner loads and high excess air
at low load, start up, warm standby
and general plant upset conditions
all mean that specific site requirements
can be met by Lanemark burners. |
