Reheating in a gas turbine

Answer & Solution
Correct Answer: Option A
Reheating is applied in a gas turbine in such a way that it increases the turbine work without increasing the compressor work or melting the turbine materials.
When a gas turbine plant has a high pressure and low pressure turbine a reheater can be applied successfully.

Wrong, reheating increases the mean temperature of heat rejection thus decreases thermal efficiency and increases specific work output.

Efficiency in a gas turbine only increases when regeneration is involved. reheating increases output work by trubine only.
