The Auxiliary Exhaust System collects steam from which pump line, classified as a noncondensing turbine-driven pump?

• A. Main-Feed Pump
• B. Boiler Feed Pump
• C. Main Condensate Pump
• D. Fuel Oil Pump

Answer: (A)

The Auxiliary Exhaust System is designed to collect exhaust from a noncondensing turbine-driven pump. In this setup, that pump is the Main-Feed Pump, whose turbine runs on steam and leaves behind exhaust that must be directed somewhere safe rather than venting into spaces. The other pumps listed either aren’t turbine-driven or aren’t part of the noncondensing exhaust path: the condensate pump handles condensed steam, and the boiler feed and fuel oil pumps are not the same noncondensing turbine-driven type that feeds the AES. So, the system collects steam from the Main-Feed Pump line.
