When water washing a boiler, the proper sequence for washing the sections should be the __________.

🔍 Key Concepts

• Function of each boiler component: generating tubes, superheater, economizer, screen tubes • Direction of normal gas flow and water/steam flow in the boiler • Purpose of water washing: removing soot and deposits without driving loosened material into still-clean sections

💭 Think About

• Think about which sections you want to clean first so loosened soot will be carried away, not pushed into already cleaned areas. • Consider the normal path of the gas flow over these components—how would reversing or following this path affect where deposits end up? • Which parts handle the driest, hottest gas versus the cooler gas, and how might that influence the order you wash them?

✅ Before You Answer

• Identify the typical gas-side flow path past the economizer, superheater, generating tubes, and screen tubes in a marine boiler. • Decide whether you want to wash with or against the normal gas flow to avoid re-contaminating cleaned surfaces. • Confirm which components are most sensitive to damage or blockage and whether they should be washed earlier or later in the sequence.
