A combustor, or burner section of a gas turbine engine made up of several individual burner cans.

These cans are long cylinders of thin sheet metal consisting of an outer housing and an inner liner, arranged axially around the power shaft of the engine, more or less parallel to it.

Discharge air from the compressor flows through the cans where fuel is sprayed into it and burned to add energy. Cooling air flows between the housing and inner liner, and through holes in the inner liner to keep the temperature of the cans low enough that they will not be damaged.

Can-type combustors were used on some of the early turbojet engines, but most modern engines use the more efficient annular, or can-annular combustors.
