🔍 Key Concepts

• Look closely at the combustion section of the turbine, where fuel is first burned. • Most marine gas turbines use redundant igniter plugs for reliability and safe light‑off. • Count the clearly labeled or drawn igniter plug locations on the combustor case in the illustration GT-0017.

💭 Think About

• On this cutaway, where would the igniters need to be placed so the flame can reliably start and spread through the entire combustor? • If one igniter failed during start, would the arrangement shown still allow the engine to light off safely? What does that suggest about the likely number? • Compare what you see here with standard practice on aero‑derivative marine gas turbines—do they usually have a single igniter or a pair?

✅ Before You Answer

• Identify the combustor can/annular combustor and zoom in on the outer casing to find all igniter symbols or labels. • Verify whether the drawing shows symmetry (e.g., one igniter on each side of the case) or only a single location. • Before choosing, ask: "Does this number provide both reliability and even ignition for this size of turbine?"
