Incineration


Waste Incineration plants (Figure 1) are composed of several units that have specific tasks, and together they recover the energetic content of Municipal Solid Waste.

The units are:

  • Waste Bunker: holds the waste and is the part where the plant operator can pick up, sort the waste and feed the incinerator using a crank.
  • Feeding Unit: pre-dries the waste and feeds the incinerator.
  • Furnace: incinerates the waste and destroys the organic component at temperatures above 800 degrees Celsius; ash and metals are recovered.
  • Boiler: utilizes the heat from the burning waste to superheat the waterpipes.
  • Energy Generation: the superheated steam is piped to a turbine generator to generate electricity.
  • Flue Gas Cleaning: remove solid and gaseous pollutants from the gas before releasing through the stack

BEST PRACTICE

Waste-to-Energy (WtE) facility

Renergia, a brand new Waste-to-Energy (WtE) facility opened in Canton Lucerne, shows that Waste-to-Energy can provide reliable heat for industries.

Category: Incineration / Waste-to-Energy plant
Executing firm: Renergia Zentralschweiz AG

MBT Ljubljana, Slovenia

In Slovenia arises one of the largest and most modern waste treatment plants in Europe.

Category: Recycling / MBT
Executing firm: STRABAG AG

Flue Gas Cleaning

The final unit of the incineration plant is one of the most important parts as it has the objective of cleaning the air pollutants produced.

Category: Incineration
Executing firm: ete.a - Ingenieurgesellschaft für Energie– und Umweltengineering & Beratung mbH

Batch Dry Fermentation

The biogas produced from the waste can be converted in a CHP to electrical and thermal energy or fed as processed bio-methane into the natural gas grid or used as fuel (CNG).
