Exam Question

### (a) What is an Exhaust Gas Economizer? Draw diagrammatic Sketch of Exhaust gas Economizer (EGE) naming each component.
An Exhaust Gas Economizer (EGE), often referred to as an Exhaust Gas Boiler or Waste Heat Recovery Boiler, is a critical component in a ship's heat recovery system. Its primary function is to recover waste heat from the hot exhaust gases of the main propulsion engine (or auxiliary engines) to generate steam, which can then be utilized for various onboard services. These services typically include:
* **Fuel heating**: For heavy fuel oil (HFO) viscosity reduction.
* **Cargo heating**: In tankers.
