In what location is heavy fuel oil kept above the flash point, but below the boiling point of water?

🔍 Key Concepts

• Flash point vs. boiling point of fuels used on ships • Typical temperature ranges for heavy fuel oil (HFO) in different parts of the fuel system • Function and normal operating temperature of settling/day tanks, mixing tanks, heaters, and purifier heaters

💭 Think About

• Which part of the HFO system is designed mainly for storage and slow warming, rather than final atomization or purification? • Where would it be unsafe or unnecessary to heat fuel close to or above water’s boiling point? • Which components normally require much higher temperatures to reduce viscosity enough for burning or separation?

✅ Before You Answer

• Compare where HFO is kept for longer periods (storage/settling vs. short‑residence equipment like heaters). • Think about which units are designed to reach very high temperatures for viscosity reduction – these are more likely to exceed 100°C. • Recall that flash point is usually well below 100°C, so you’re looking for a place where the fuel is warm (above flash point) but still cooler than 100°C during normal operation.
