🔍 Key Concepts

• Boiler economizer location in the steam plant cycle • Order of energy recovery devices: air preheater vs economizer • Path of feedwater and flue gas around the boiler

💭 Think About

• Think about which fluid passes through the economizer and where it comes from before entering the main boiler drums or tubes. • Consider what part of the plant uses waste heat from the exhaust gases just before they leave the uptake or stack. • Ask yourself: does the economizer act on a gas or a liquid in the steam cycle?

✅ Before You Answer

• Identify whether the economizer is in the flue gas path or the steam path. • Trace the feedwater flow from the condenser/hotwell, through pumps, heaters, and into the boiler. • Distinguish between the device that heats air for combustion and the one that heats water using exhaust gas heat.
