Question 32Gas Turbine - Assistant Engineer

The correct answer is C) Annular. The GE LM2500 gas turbine uses an annular combustor design. In an annular combustor, the fuel is injected into an annular (ring-shaped) combustion chamber, where it is mixed with air and burned. This design is more efficient and compact compared to other combustor types like can or can-annular designs. The other options are incorrect because: A) Can-annular has separate can-type combustion chambers arranged in an annular fashion, B) Can has individual can-type combustion chambers, and D) Cannular is not a common combustor type used in gas turbines.
