How can the electrical energy consumption of a waste incineration plant be reduced?
A waste incineration plant uses the energy contained in waste to produce steam, which in turn is advantageously converted into electrical energy. Waste is the sole fuel for energy production. Due to technological constraints, only about 85% of the contained thermal energy can be utilized. The electrically operated aggregates consume about 2.5 to 4% of the up to 35% generated electrical energy. The rest is fed into the grid. Exhaust steam, which remains downstream the turbine, can be used advantageously for heating purposes in the district heating network. Where such a network is not available, the exhaust steam must be condensed to water in a condenser to be fed back to the steam boiler.
