Fuel Nozzle Functions
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.
