🔍 Key Concepts

• Typical fuel pressure requirements for marine gas turbine combustion systems • Why gas turbines need fine atomization of fuel compared to diesel engines • Relationship between pressure, nozzle design, and clean combustion

💭 Think About

• Think about how much pressure is usually needed to spray fuel as a fine mist into a high‑speed gas turbine combustor, not just to move it through piping. • Compare these pressures to what you might expect from a diesel engine’s supply system versus its injection pressure—where would a gas turbine’s service pressure logically fall? • Consider which pressure range would be high enough to ensure good atomization, but still reasonable for a continuous service pump without being an extreme injection pressure.

✅ Before You Answer

• Eliminate any pressures that seem too low to properly atomize fuel in a gas turbine combustor. • Eliminate any pressures that seem more like diesel injection pressures than service/supply pressures. • Ask: which range looks like a moderate, continuous service pressure suitable for a pump that runs steadily with reasonable power demand?
