2. 3-Multi - Can Annular Combustor

3. 3-Multi - Can-Annular Combustor The third design and the one preferred by most manufacturers, is the can-annular combustor, a combination of the single combustion chamber and the annular.

4. TURBINE SECTION (EXPANTION SECTION) This transition duct, located between the combustion chambers and the turbine-nozzle guide vanes, insures a final mixing of the hot gases.
