A steam trap's function is to

  • A.discharge condensate while holding back steam
  • B.reduce the pressure of the steam passing it
  • C.separate air from the steam in the main
  • D.regulate the flow of steam to the plant

Answer: A

Condensate in a main causes water hammer and blocks heat transfer, so it must be removed, and any trap that also passes steam is throwing away fuel. Testing traps regularly is among the most profitable routine tasks in a steam plant.
