Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the core functionality?Heat exchanger designed for energy recovery from process outputs
2. What is the thermodynamic principle?Leverages heat transfer (convection, conduction) to move thermal energy
3. How does a Waste Heat Recovery Unit help the environment?It uses heat that would otherwise be lost, so factories burn less fuel and release fewer gases like CO2 and NOx.
4. Why are Waste Heat Recovery Units important for factories?They make the whole power system work better, often getting more than 90% efficiency, and they lower the cost of energy.

Heat Exchanger: A device that facilitates the transfer of thermal energy between two or more fluids.
Cogeneration (CHP): Simultaneous generation of electricity and useful thermal energy from a single fuel source.
Thermodynamics: The branch of physics dealing with heat and its relation to other forms of energy and work.
Flue Gas: Gaseous products of burning fuel, typically containing nitrogen, carbon dioxide, and water vapor.
