🔍 Key Concepts

• Review the basic types of gas turbine combustors used in marine and aviation applications (can, annular, cannular, can-annular). • Think about how large aero-derivative turbines (derived from aircraft engines) typically arrange their combustion chambers around the engine axis. • Consider what the name "LM" (Land and Marine) implies about the GE LM2500’s origin from an aircraft engine design.

💭 Think About

• Ask yourself: in a high-power aero-derivative turbine like the LM2500, is a single continuous ring combustor or multiple discrete cans more common? • Compare how maintenance access and modular replacement might influence the choice between can, annular, and can-annular designs. • Think about which combustor type combines features of both individual cans and an annular flow path, and how that might benefit a marine gas turbine.

✅ Before You Answer

• Be clear on the definition of each combustor type: can, annular, cannular, can-annular—how are the burners arranged? • Confirm which combustor style is most commonly associated with GE aero-derivative turbines in the same family as the LM2500. • Before picking, visualize: does the LM2500 have multiple separate cans, a single ring, or a hybrid arrangement? Match that mental picture to the closest combustor term in the choices.
