Factors affecting fuel nozzle MTBR’s
 Maintenance intervals can be radically
different among engine types
 Range
• Several hundred to thousands of hours
• Depending on engine and design
 Why??
Factors affecting fuel nozzle MTBR’s

Factors affecting removal intervals:
 Nozzle type
 Operating environment of combustor
 Passage sizes
 Split between flow rates
 Manufacturing cost vs. maintenance cost as a design
criteria
 Current designs generally have higher MTBR’s
Simplex Pressure Atomizer

Advantages
 Simplest form of
atomization.
 Easier to manage thermal
environment due to single
circuit design.
 Spray angle consistent over
operating range.
 Spray Angle typically 30° 70°.
 Lowest cost.

Disadvantages
 Limited by turndown ratio of
engine (max flow / min
flow)
 Presents greater challenge
to meet smoke and
emissions requirements.
 Wider spray angles subject
to instability.
 Difficult to product narrow
angle with higher FN.
Duplex Pressure Atomizer

Advantages
 Global SMD droplet size
larger when secondary
circuit cuts in.
 Spray angles consistent
over operating range.
 Provides the best ignition
characteristics.
 Disadvantages
 Fuel system requires flow divider
valve.
 Small internal fuel passages
which increases the propensity
of internal carbon.
 Presents greater challenge to
manage thermal environment
due to multiple fuel circuit
design.
 Higher cost.
Pure Air-blast Nozzle

Advantages
 Only utilizes a single fuel
circuit.
 Large internal fuel
passages which reduces
the propensity of internal
carbon.
 Longer life than piloted
airblast design.
 Low to moderate cost.

Disadvantages
 Typical FN should be
greater than 4.0.
 Larger SMD droplet sizes
at ignition compared to
piloted airblast.
 Tip requires additional
heatshielding due to T3 air
flowing through nozzle.
Piloted Air-blast Nozzle

Advantages
 Achieves the smallest
global SMD droplet size
compared to all other
configurations.
 Provides the best ignition
characteristics.
 Disadvantages
 Requires flow divider valve.
 Small internal fuel passages
which increases the
propensity of internal carbon.
 Presents greater challenge to
manage thermal environment
due to multiple fuel circuit
design.
 Highest overall cost.
