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

BURNERS
•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.

6. 6SWT/FTC

BURNERS
•Principle: Atomization of well effluent -> reduction in
fine droplets
•Needs: -propane for pilots
-electricity for lodge boxes (spark plug)
-Schlumberger 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 - Atomization process
High 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

BURNERS
•Features:
-Gas pilot light
-locate below the atomizer
-small propane burner & spark
plug
-lit by sending high voltage from a
remote control box (lodge box)

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 axisoil

11. 11SWT/FTC

BURNERS - Air Supply
•Never use rig air supply: Always
use Schlumberger 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” or 4”in, (300psi WP) hose, ended
with weco-union to booms inlet.

12. 12SWT/FTC
10/25/25
BURNERS – Oil circuit
•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
•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.

23. 23SWT/FTC

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

24. 24SWT/FTC

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.

SAFETY ASPECTS FOR HANGING OFF A BOOM

•Standby boat in constant contact with by
radio
•WT supervisor to get a work permit
•Everybody working on the boom wears a life
vest
•Not compulsory to be attached with a safety
harness
•Preferably this operation is carried out by
daylight
•Consider weather situation
