What could be the cause of water hammer in a steam heating system?

🔍 Key Concepts

• Water hammer in steam and condensate piping • Effect of condensation of steam in a cold line • Difference between actions inside the boiler vs. in the distribution piping

💭 Think About

• Which option would most likely trap or suddenly move condensate in a line where steam is flowing or being admitted? • How does introducing steam into a cold pipe change the state of the steam and the volume of water inside that pipe? • Which options are mainly about boiler filling practice, and which are about what happens inside the steam line itself?

✅ Before You Answer

• Identify which choices involve piping or lines rather than just the boiler shell • Ask: in which situation can you get rapid condensation that leads to slugs of water driven by steam? • Eliminate options that would not normally create sudden, high-velocity movement of condensate inside the line
