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.
