š Key Concepts
ā¢ Trace where the steam is coming from and where it is going in the diagram (boilers, heaters, ejectors, soot blowers, etc.).
ā¢ Compare the services shown (soot blowing, tank cleaning heater, air ejectors, burner atomizing steam) with what each listed piping system normally supplies.
ā¢ Recall the difference between feedwater systems, exhaust systems, and auxiliary steam systems on a steam plant.
š Think About
ā¢ Look at the labels near the boilers and follow the lines: what type of fluid and pressure level does this system appear to be distributing?
ā¢ Which of the listed systems would logically supply steam to soot blowers, tank cleaning heaters, and air ejectors?
ā¢ Would a main feed system or Butterworth system normally connect to air ejectors and burner atomizing lines, or is that handled by a different system?

Before You Answer
ā¢ Confirm whether the lines feed steam-consuming auxiliaries (ejectors, heaters, soot blowers) or return condensate/feedwater.
ā¢ Verify if any part of the diagram shows typical feed pump suction/discharge or condensate return piping associated with a main feed system.
ā¢ Check whether the labeling indicates a connection from auxiliary exhaust and to auxiliary steam system, and consider which choice that best matches.
