Questions and Answers

What is the purpose of inspecting the boiler internally before closing it up?

  • To ensure it is free from scale, oil, tools, debris, and other foreign material (correct)
  • To check the alignment of the burners and ensure they are ready for firing
  • To confirm the secure installation of internal baffles and steam drum internals
  • To inspect the external components of the boiler for any damage or corrosion

    • Why is it important to check off all tools removed from a watertube boiler's water side?

  • To make sure that the burners are clean and ready for firing
  • To prevent the gaskets from sticking to the metal
  • To ensure that no foreign objects have fallen into the water tube (correct)

    • What should be used to prevent gaskets from sticking to the metal when closing up the boiler?

  • Adhesive tape
  • Silicone sealant
  • Graphite paste (correct)
  • Oil-based lubricant
