Plant Efficiency

Question 1

What limits the efficiency of a plant?

Answer 1

The high of the vaporization of the working fluid.

Question 2

How does temperature affect efficiency ina plant?

Answer 2

Steam. If ally has pressure point which is directly tied to temperature increase.
Eg. Most sepercritical plant have a steam pressure point of about 34Mpa this allows temperature
Levels with the machine to reach b/n 538 degrees and 566degrees. Which then results in the plants efficiency being 40%.

If the steam pressure point increases to 31Mpa then the fluid is a ultra supercritical fluid and has temperature range of 600 degrees which ensures and efficiency of 42%.

So this means that the higher the temperature the higher the efficiency.
