BURNERS
Lecture Objectives:
By the end of this lecture, YOU should be able to: Understand the different atomization systems,
circuits and pilot ignition Describe the various burners types Identify most important technical characteristics
Dispose of the oil at the surface during a well test. Avoid oil storage and pollution problems. Limit heat radiation on rigs.
Burners are installed on long booms to keep them a safe
distance from the rig.
BURNERS
• Principle: Atomization of well effluent -> reduction in fine droplets
• Needs: - propane for pilots
- electricity for lodge boxes (spark plug)
- air compressors (do not use rig air)
- water mainly to prevent heat radiation
• Classified by number of combustion heads: determines maximum oil flow rate
BURNERS
BURNERS - Atomization processHigh Efficiency Sea Dragon (Green Dragon)
• Combustion achieved with atomizers.
• Air and oil combined before ignition
by pilots
• Nozzle combination: - 11mm for oil
- 22mm for air
• Refer to datasheets for burner
capabilities
• Refer to FOH for efficient burning guidelines
Features: Hearth to guide air

Features:

BURNERS
Features:
Swivel joint Acts as a pivot to support the whole
burner
Allows the burner to be positioned
up to 75 degrees on either side of
the horizontal axis
BURNERS
Never use rig air supply: Always use
compressors
A check valve is mounted on the air line
upstream the atomizers to prevent the
oil/effluent from entering into the air line
and compressor’s engine.
Fit compressor air outlet with an extra check
valve.
2” air LP (300psi WP) hose, ended with
weco-union to booms inlet.
BURNERS – Air Supply
A check valve is mounted on the oil
line upstream the atomizers to
prevent air passing from the
atomizer into the oil line.
A typical situation in which this might
occur is during the start up
procedure for the burners because
air is sent to the atomizers before
the oil is sent.

BOOMS
Lecture Objectives:
By the end of this lecture, YOU should be able to: Describe the basic functions Identify & Select the different types State the basic goals of rigging up, in terms of
safety
The burner is mounted on a boom to keep it away from the rig To reduce heat radiation and the risk of fire Heat radiation also controlled with water curtains on boom
Provides Gas flare(s) pipe and piping to supply Air, Water, Oil and Propane.
For safe burning in changing winds, two booms are usually installed on opposite sides of a drilling rig.
BOOMS
• Lengths: 60 or 85ft (heat radiation concern)• Structure: -”U”-shape (UBM-F/G) Standard boom
-”V”-shape (UBB-A/B) Heavy-duty boom• Equipment required for
installation: -base plate-king post-horizontal guy-lines-vertical guy-lines
BOOMS
Mounted on the rig with a Rotating Base Plate, to allow horizontal and vertical movements, and Guy Lines.
Horizontal guy lines are used to orient the boom. Vertical guy lines, fixed to the King post or rig structure,
support the boom.
BOOMS
USUALLY but not always:– 60ft boom: up to 10000 bopd– 85ft boom: above 10000 bopd– Standard “U”-booms equipped with 1 gas flare
- optional: 2 flares– Heavy-duty “V”-booms equipped with 2 gas flares
- optional: 3 flares
