When a waste heat boiler is installed in the exhaust of a main propulsion diesel engine, the exhaust gas bypass would be used __________.

🔍 Key Concepts

• waste heat boiler operation in diesel exhaust systems • effects of engine load on exhaust gas temperature and boiler condition • why low exhaust temperatures can lead to corrosion inside boilers

💭 Think About

• Think about what happens to exhaust gas temperature when a diesel engine is at very low load versus very high load. • Ask yourself: when would you want to route exhaust around (bypass) the boiler to protect it from damage or premature failure? • Consider whether high steam demand means you want more or less exhaust gas going through the boiler.

✅ Before You Answer

• Verify what temperature conditions tend to promote sulfuric acid condensation and corrosion inside boiler tubes. • Check whether bypassing the boiler would reduce or increase steam production. • Confirm how engine load (low vs high) affects the need to protect the boiler from overheating versus corrosion.
