🔍 Key Concepts

• Trace where the steam is coming from and where it is going in the diagram (boilers, heaters, ejectors, soot blowers, etc.). • Compare the services shown (soot blowing, tank cleaning heater, air ejectors, burner atomizing steam) with what each listed piping system normally supplies. • Recall the difference between feedwater systems, exhaust systems, and auxiliary steam systems on a steam plant.

💭 Think About

• 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? • Which of the listed systems would logically supply steam to soot blowers, tank cleaning heaters, and air ejectors? • 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

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