Question 1 of 27070

If the feed pump for an auxiliary boiler fails to deliver the feed water to the boiler, the cause may be __________.

🔍 Key Concepts

• Relationship between feedwater temperature and pump suction conditions • Effect of steam pressure on delivering water into the boiler drum • How cavitation or loss of suction can cause a pump to stop delivering water

💭 Think About

• Think about which factor would most directly affect the pump’s ability to take suction and build discharge pressure: temperature of water, boiler pressure, or steam demand? • Which condition could cause vapor formation at the pump suction, reducing pump output even though the pump is running? • Which options describe conditions in the boiler versus conditions right at the pump suction?

✅ Before You Answer

• Compare the feedwater temperature in each option with the likelihood of forming steam/vapor at the pump suction. • Ask whether boiler steam pressure alone would suddenly stop a correctly sized feed pump from delivering water. • Consider whether steam demand changes the pump’s mechanical ability to move water, or just how much water is required.

Question 1 of 27070

If the feed pump for an auxiliary boiler fails to deliver the feed water to the boiler, the cause may be __________.

high steam pressure in the boiler

abnormally high feed water temperature

abnormally high boiler water temperature

steam demand exceeding feed pump capacity
