🔍 Key Concepts

• function of a superheater and its vents in a fire-tube or water-tube marine boiler • what happens to steam pressure and metal temperature in the superheater when steam flow is low or stopped • which operations involve no steam flow through the superheater vs. normal or high steam flow

💭 Think About

• For each choice, ask: Is steam actually flowing through the superheater elements during this operation, or is it mostly stagnant? • When is there a risk of trapping expanding steam in a closed space that is being heated, and how do vents prevent that? • Which operation is specifically associated with initial firing and warming of the boiler before putting the superheater on the line?

✅ Before You Answer

• Identify which option corresponds to the period when the boiler is being first brought on the line from cold or idle • Check when the manufacturer/standard practice says to have superheater drains/vents opened to atmosphere to prevent overheating and water hammer • Eliminate options that are more about routine maintenance (tubes/blowdown) rather than starting and safely warming the boiler and superheater
