In turn, this increases the efficiency of the power turbines (21).

In the indirect system, a heat exchanger is used and only clean air with no combustion products travels through the power turbine.

Additionally, after harvest, it can be burned to produce heat and steam for power turbines.

So, in effect, the power turbine has 14 stages.

The steam is then used to power electric turbines which make electricity.

The smaller head means that the water velocity is much lower and more lower power turbines are required.

With mechanical transmission, the power turbine must be capable of starting from rest, so a more complex arrangement is necessary.

"An oversight But then no one invited you to blunder into our power turbine's exhaust current."

During later periods of high electrical demand, the air is released to power turbines, generally using supplemental natural gas.

The power turbine was then fitted in the empty space below, mounted at a right angle to the engine.
