Disadvantages of Closed Cycle Over Open Cycle | ||
---|---|---|
1. | As the system is under an initial high pressure with a working medium other than air, therefore the system should be gastight. This increase the cost of the system. | In open cycle system the combustion chamber is lighter in weight and smaller in size with a high rate of heat release that's why the system is quit cheaper then closed cycle system. |
2. | A large air heater is needed and this air heater is not as sufficient as the combustion chamber used in open cycle. | The combustion chamber of open cycle system is more efficient and suitable for large quantity of air. |
3. | As the system needs cooling water so the system cannot be used in aeronautical engines. | Cooling water is not needed to except in those turbine using intercooler. This property is quite advantages in marine aviation etc. |
