Fired Heaters – KS

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.
