🔍 Key Concepts

• Waste heat boiler / exhaust gas economizer operation at full sea speed • Role of a boiler steam drum/upper drum (steam space vs water space) • How water from area B interacts with the space marked L in the diagram

💭 Think About

• Trace the flow of water/steam from the exhaust gas side (area B) toward the main boiler body. What happens to that fluid when it reaches the upper part of the boiler? • Look at the burner section near J. At full sea speed, is the oil-fired burner normally the main source of heat, or is it the engine exhaust? How does that change the job of the space L? • In a typical boiler, which part is used to separate and collect steam and what happens when very hot feedwater enters that space?

✅ Before You Answer

• Confirm whether L is in the gas path or in the steam/water side of the boiler. • Check how the line coming from B connects into the drum that contains L—does it enter above or below the normal water level? • Decide whether L is upstream (heating water), or downstream (collecting/handling steam) relative to the coils in B. This will rule out options involving preheating feedwater or superheating steam.
