Rational energy management was the focal-point in designing the fluidised bed installation. The furnaces are therefore built to recover energy efficiently. 

The heat generated from the thermal treatment is recovered in a vertical steam boiler. The steam boiler consists of a network of water channels. The heat from the flue gases turns the water into high-pressure steam. Turbines convert the steam produced into electricity.

If all of the energy that SLECO recovers from thermal treatment was converted into electricity, we would be able to supply around 100,000 households with energy each year.
