Q

The diesel engine exhaust gas bypass, as fitted with some waste heat boilers, is installed to __________.

🔍 Key Concepts

• Waste heat boiler purpose and operation • Effect of engine load on exhaust gas temperature and flow • Relationship between exhaust gas bypassing and what happens inside the boiler (soot, corrosion, heat recovery)

💭 Think About

• Think about what changes in the exhaust gas when the engine is running at low load versus heavy load. • Ask: When would it be harmful for ALL exhaust gas to go through the waste heat boiler? What problem would that cause? • Consider which option is about protecting equipment versus which are about improving efficiency or fuel consumption.

✅ Before You Answer

• Check how exhaust gas temperature and dew point of acidic condensate relate to corrosion in boiler tubes. • Verify whether high or low engine load is more likely to cause problems inside a waste heat boiler if there is no bypass. • Make sure the choice you select directly involves the reason to divert exhaust around the boiler, not just a general benefit of better efficiency.
