Intercooling in gas turbines
A. Decreases net output but increases thermal efficiency
B. Increases net output but decreases thermal efficiency
C. Decreases net output and thermal efficiency both
D. Increases net output and thermal efficiency both
Answer: Option D

B is correct option
An intercooling regenerative cycle can increase the power output and the adiabatic thermal efficiency. This combination provides an increase in efficiency of about 12% and an increase in power output of about 30%,
No...thermal efficiency gets reduced...B is correct.
