Question 1 of 27070

Air used to cool the combustion liners and turbine components is referred to as which of the following?

🔍 Key Concepts

• Difference between primary air and secondary air in gas turbines • Purpose of air that mixes with fuel versus air that cools turbine parts • Understanding what control air is usually used for on machinery

💭 Think About

• In a gas turbine combustor, which air stream is mainly responsible for actually burning the fuel and stabilizing the flame? • Which air stream is directed around or through holes in the liners and turbine components to keep metal temperatures safe? • Is control air normally routed to combustion and turbine parts, or is it usually used for instruments, actuators, and valves?

✅ Before You Answer

• Identify which term is commonly associated with cooling of metal parts rather than combustion • Verify that primary air is the portion that supports and stabilizes combustion • Confirm how control air is typically defined in marine/industrial systems (often dry, clean air for controls, not for component cooling)
