For maintenance, how can you reach the burner units of a can-annular combustor?

Correct Answer: Option C — By sliding the can-annular case aside

Can-annular combustor designs feature individual burner cans housed within a common casing. Maintenance accessibility is achieved by sliding the outer casing sections aside, which exposes the individual burner units. This modular design allows for the inspection or replacement of specific nozzles and liners without requiring complete engine disassembly.
