🔍 Key Concepts

• Purpose of soot blowing and what can be damaged by doing it incorrectly • Effects of water/condensate inside hot steam lines and soot blowers • Why proper warming-up procedures are critical for any steam supply piping

💭 Think About

• Before you blow tubes, what condition do you want the steam supply piping to be in: cold with condensate, or hot and dry? Why? • What can happen to the piping, valves, or boiler if you suddenly admit high‑pressure steam into cold, condensate‑filled lines? • Think about standard steam line start‑up: do you normally prioritize opening drains, warming up slowly, or increasing draft first?

✅ Before You Answer

• Verify which action directly prevents water hammer and thermal shock in the steam lines. • Consider which step ensures that any condensate is removed from the soot blower steam supply piping before full-pressure steam is admitted. • Ask yourself which option (or combination) best matches normal steam system start‑up practice on boilers.
