🔍 Key Concepts

• proper securing sequence of a fired boiler after removing fuel • purpose of superheater vents and when they should be open or closed • effect of residual heat and steam expansion after fuel is shut off

💭 Think About

• After you stop the fuel, what is still happening inside the furnace, tubes, and superheater for several minutes? • Which item in the choices is related to safely handling steam formed by leftover heat, rather than air or water flow? • If you close something too early while metal parts are still very hot, what unsafe pressure or temperature condition could develop?

✅ Before You Answer

• Identify which components deal directly with removing or venting steam vs. controlling air or feedwater • Think about which step must wait until after steam flow and metal temperature have safely decreased • Ask: which action, if done immediately after fuel shutoff, could trap expanding steam instead of letting it escape?
