During routine maintenance, in which combustion chamber type is the case and liner removed and installed as one unit?

• A. Can-Type
• B. Annular Type
• C. Can-Annular Type
• D. Diffusion-Type

Answer: (A)

In a can-type combustor, each combustion chamber is built as a separate can that includes its own liner inside a surrounding case. Because the liner is housed inside and paired with its own case, the entire can assembly can be unbolted and pulled out as a single unit for maintenance. This makes inspection and replacement straightforward, since you’re dealing with one self-contained chamber rather than a section of the overall combustor. This differs from annular types, where the combustion chamber is a continuous ring around the core, so you don’t remove a single can with its liner as one unit. In diffusion-type designs, the arrangement and service approach differ as well, typically focusing on the individual flame tubes rather than a detachable can-within-a-case unit.
