The closed cycle gas turbine plants are external combustion plants.

In the closed cycle gas turbine, the pressure range depends upon the atmospheric pressure.

The advantage of efficient internal combustion is eliminated as the closed cycle has an external surface.

In open cycle gas turbine, atmosphere acts as a sink and no coolant is required.

It is used as the alternate standard of comparison of all heat engines.

All the heat engines are based on Carnot cycle.

It provides concept of maximising work output between the two temperature limits.
