🔍 Key Concepts

• Function of boiler fuel oil system strainers in removing contaminants • Difference between strainers on the suction (inlet) vs discharge (outlet) side of pumps • Why these are called 'hot' strainers in relation to fuel oil temperature and viscosity

💭 Think About

• Think about where in the fuel oil system heated fuel is typically filtered just before it reaches the burners. • Consider which term best matches a strainer that handles high‑temperature, low‑viscosity fuel oil, and is designed for continuous operation. • Ask yourself which option is a common engineering term you’ve seen in fuel oil system diagrams or boiler room layouts.

✅ Before You Answer

• Check which answer choices are actually standard marine engineering terms used in fuel oil systems. • Consider that magnetic strainers are for particular types of contaminants—does that match hot fuel oil service? • Think about whether the term you choose logically fits with the idea of fuel being heated and flowing toward the boiler burners.
