🔍 Key Concepts

• Trace the flow of water/steam between the right-hand steam drum and the left-hand heat exchanger marked by component 1. • Think about what happens to boiler water when it passes through tubes exposed to engine exhaust gas. • Review the differences between economizer/evaporator, superheater, and condenser functions in a waste‑heat boiler system.

💭 Think About

• Look at where the fluid entering component 1 comes from and where it goes afterward—does it return to the steam drum, go to the turbine, or go back to the feed system? • Ask yourself: is the steam leaving component 1 likely to be saturated or superheated, based on what equipment appears downstream before it reaches the turbine? • Which option describes what typically occurs inside exhaust‑gas‑heated tube banks in a waste‑heat boiler connected to a steam drum?.

✅ Before You Answer

• Confirm whether any separate superheater section is shown between the steam drum and turbine; if not, what kind of steam is most likely produced at this stage? • Verify that component 1 is directly in the engine exhaust gas path, indicating its role as a heat‑absorbing surface rather than level control equipment. • Eliminate any choice that would require heat removal (condensing) instead of heat addition (evaporation) in the presence of hot exhaust gas.

As shown in the illustration, the function of component "1" is to ________. Illustration MO-0128

generate superheated steam to operate the turbo-generator

evaporate circulating boiler water into saturated steam

condense excess steam produced in the boiler
