Q

In a regenerative or recuperative gas turbine cycle configuration, the heat of the turbine exhaust gas is used to do what?

🔍 Key Concepts

• Regenerative / recuperative gas turbine cycle basic purpose • Energy recovery from turbine exhaust gas • Where heat is most useful in the Brayton (gas turbine) cycle

💭 Think About

• In a simple gas turbine cycle, at what point is the working fluid at high pressure but relatively low temperature, and would most benefit from additional heat? • If you add heat before the turbine, how does that affect the fuel required in the combustor for the same turbine inlet temperature? • Which option describes pre‑heating a stream that will go into the combustor, rather than heating gas after combustion?

✅ Before You Answer

• Identify which choices involve air/gas before combustion versus after combustion • Recall that regeneration aims to reduce fuel consumption by using exhaust heat to pre‑heat the working fluid entering the combustor • Check which choice would not change the turbine inlet temperature for a given fuel flow, which would contradict the purpose of regeneration
