Heat Exchanger in Simple Ideal Gas Turbine Cycle
Introduction:
A gas turbine cycle is a thermodynamic cycle that is used to convert thermal energy into mechanical energy. In a simple ideal gas turbine cycle, air is compressed, heated, expanded through a turbine, and then cooled. This cycle can be improved by adding a heat exchanger.
Improvement in Efficiency:
Adding a heat exchanger to a simple ideal gas turbine cycle improves the efficiency of the cycle. The heat exchanger is used to transfer heat from the hot exhaust gases to the compressed air that is entering the combustion chamber. This preheated air requires less heat to be added during the combustion process, reducing the fuel required to achieve the same power output. This improves the efficiency of the cycle.
Improvement in Work Output:
When a heat exchanger is added to a simple ideal gas turbine cycle, it improves the efficiency of the cycle, which in turn improves the work output. This is because the amount of work output is directly proportional to the efficiency of the cycle. The higher the efficiency, the more work output can be obtained from the same amount of fuel.
Conclusion:
The addition of a heat exchanger to a simple ideal gas turbine cycle is a beneficial improvement to the cycle. It improves both the efficiency and work output of the cycle. By preheating the compressed air, less fuel is required to achieve the same power output, which improves the efficiency of the cycle. This improved efficiency results in an increase in work output.
