Why does the pressure in the burner of a gas turbine engine drop when you are increasing the internal energy of the air?

The burning occurs at a higher pressure than free stream because of the action of the compressor. The pressure in the burner remains nearly constant during burning, decreasing by only 1 to 2 per cent.
The gas turbine burner pressure is responsible for igniting the fuel-air mixture in the combustion chamber of a gas turbine engine. It creates a high pressure environment that allows for efficient burning of the fuel, producing hot gases that drive the turbine blades and generate power.
Gas turbine burner pressure is typically measured in pounds per square inch (psi) or kilopascals (kPa). This is done using pressure sensors located at various points in the combustion chamber and connected to instrumentation that displays the pressure readings.
Several factors can affect gas turbine burner pressure, including the type and quality of fuel being used, the ambient temperature and pressure, and the condition of the engine components. Changes in any of these factors can impact the efficiency and performance of the gas turbine burner pressure.
Gas turbine burner pressure can be controlled through the use of a fuel control system, which regulates the flow of fuel into the combustion chamber. This allows for precise control of the fuel-air mixture and helps maintain a stable and optimal pressure for efficient combustion.
If gas turbine burner pressure is not properly controlled and maintained, it can lead to unstable combustion, which can result in flameouts or even explosions. It is important for gas turbine engines to have reliable pressure sensors and fuel control systems to prevent these risks and ensure safe and efficient operation.
