What type of gas turbine cycle configuration is shown in the illustration? See illustration GT-0031

Correct Answer: Option D — Intercooled-recuperated type.

The intercooled-recuperated (ICR) cycle utilizes an intercooler between compressor stages to reduce work input and a recuperator to preheat combustion air using exhaust heat. This configuration significantly improves thermal efficiency by recovering energy that would otherwise be lost through the exhaust stack.
