Waste is not only burned in an incineration plant, but also used energetically. Waste incineration reduces the volume of waste by 90%! Coarse fractions such as bulky refuse are crushed in the waste bunker.
The garbage in the bunker is mixed thoroughly in order to achieve a good mixture of low and high energy-containing fractions. This ensures homogeneous combustion characteristics in the boiler.
Remaining 10% Residual Material Is Recycled
Large grippers transfer the mixed waste to the feed hopper at regular intervals. The lump of waste then falls on the incineration grate by its own weight. Incineration then takes place in the boiler without addition of fossil fuels.
Once the waste is completely burnt, the slag at the end of the incineration grate slides into a water bath. After cooling, the reaction-neutral slag is processed. Metals are filtered out by means of a metal separator and reused.
Waste has a high calorific value. Energy liberated during incineration is used for generation of electric power and district heat as well as for production of process steam.
