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 Applications Specifications Rigging up (animations) Safety aspects

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
