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.
