Our HC range of gas fired, round flame burners provide the process heat for down-fired steam reforming to produce ammonia – commonly used in making fertiliser.
These burners contribute to the reaction which ‘reforms’ the reformer feed stock – typically natural gas or naphtha, which results in ammonia or urea.
Core features of the Lanemark HC petrochemical burner
Stable flame profile
A tightly controlled flame allows for 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. These 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.
Flexible firing arrangements
Our HC 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.
Further HC petrochemical burner features
- Different ignition options. 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.
- Varied fuel types. 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.
- Low emissions. 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.
- Reduced noise. 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.
- Flexible to site needs. Our HC burners can meet a range of specific site conditions and environments, namely:
- Flame lengths of less than 3m with diameters of under 0.7m
- Low excess air operation at design or normal burner loads and high excess air at low load
- Start up and warm standby conditions
