Ammonia – HC

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.
