What is the primary function of the combustion chamber in a gas turbine?

• A. To compress incoming air
• B. To ignite air-fuel mixture creating energy
• C. To expel exhaust gases
• D. To cool the turbine

Answer: (B)

The burning inside the chamber is where chemical energy from the fuel is converted into thermal energy, by burning the fuel that’s mixed with the compressed air. This creates a hot, high-pressure gas that expands through the turbine, delivering the energy that turns the engine’s shaft. In other words, the chamber sustains the combustion process to release heat and produce the high-energy gas the turbine needs. It’s not responsible for compressing air, cooling the turbine, or expelling exhaust—the compressor handles compression, cooling systems manage blade temperatures, and the turbine/exhaust handle gas flow after combustion.
