What is the main purpose of the combustion chamber in a gas turbine?

The main purpose of the combustion chamber in a gas turbine is to facilitate the combustion of the fuel-air mixture. In the combustion chamber, compressed air from the compressor mixes with fuel injected into the chamber. This mixture is ignited, resulting in a rapid expansion of hot gases, which then flow through the turbine. The combustion process is essential for converting the chemical energy stored in the fuel into thermal energy, which is then transformed into mechanical energy as the turbine spins.

The combustion chamber's design is crucial for ensuring efficient and stable combustion while managing temperatures and pressures that can affect the overall performance of the gas turbine. Proper mixing and combustion help maximize the energy extracted from the fuel, contributing to the turbine's power output and efficiency.
