🔍 Key Concepts

• Exhaust gas economizer and how it fits into the overall waste-heat boiler system • The flow path of water/steam between the steam drum and the exhaust gas unit (follow the colored piping and arrows) • The difference between heating water, condensing steam, maintaining drum level, and superheating steam

💭 Think About

• Look closely at where component "B" is located in relation to the exhaust gas inlet and outlet. Is it in the gas path, the water/steam space, or somewhere else? • Trace the piping connected to "B": does it carry steam away, water to the drum, or something that would control level or condense steam? • Ask yourself: is this part adding heat to water, removing heat from steam, or simply controlling the amount/level of water in the drum?

✅ Before You Answer

• Verify whether exhaust gas passes directly over/through the part labeled "B" or through the tubes marked "C". • Confirm if any line from "B" goes to a condenser or cooling water source (needed if it were condensing excess steam). • Check whether "B" has any connection to a level-control device on the steam drum, or to equipment clearly marked for superheated steam to a turbo‑generator.
