How does waste to Energy Work?
The process of generating electricity in a mass-burn waste-to-energy plant has seven stages
- Waste is dumped from garbage trucks into a large pit.
- A giant claw on a crane grabs waste and dumps it in a combustion chamber.
- The waste (fuel) is burned, releasing heat.
- The heat turns water into steam in a boiler.
- The high-pressure steam turns the blades of a turbine generator to produce electricity.
- An air pollution control system removes pollutants from the combustion gas before it is released through a smoke stack.
- Ash is collected from the boiler and the air pollution control system.
