🔍 Key Concepts

• Typical waste heat boiler arrangement on medium-speed and slow-speed diesel propulsion plants • Differences between fire-tube / dry-back boilers and water-tube boilers in terms of circulation and pressure capability • Where gas flow and where water/steam flow in common marine boiler designs

💭 Think About

• Think about which boiler construction is best suited to using exhaust gas from a diesel engine to heat water without a separate furnace • Consider which type of boiler is more common on modern ships when you need higher pressure steam and easier heat recovery from engine uptakes • Ask yourself: does a waste heat boiler usually have water in tubes surrounded by hot gas, or gas in tubes surrounded by water?

✅ Before You Answer

• Verify which boiler type is most common for marine exhaust gas / economizer / waste heat boilers • Check which of the listed types is especially suited for higher pressures and quick heat transfer in compact spaces • Eliminate any option that depends on a separate fired furnace rather than primarily using exhaust gas heat
