🔍 Key Concepts

• Boiler tube cleaning methods in steam plants • Difference between cleaning the gas side (fireside) and water/steam side of a boiler • Where soot forms versus where scale/mineral deposits form

💭 Think About

• When engineers say they are "blowing tubes," which side of the boiler are they usually working on: the fire/gas side or the water side? • What type of deposit is most likely to build up where hot combustion gases flow past tube surfaces? • How does removing that specific deposit affect heat transfer and overall boiler performance?

✅ Before You Answer

• Identify whether tube blowing is normally done with steam or water and on which side of the boiler that’s used • Match each choice with the location it’s talking about: stack, firebox, water tubes, overall boiler • Decide which option best describes the direct action of blowing tubes, not just a side benefit or a different maintenance task
