In Waste-to-Energy plants, electricity is produced through a steam turbine – generator set. When producing electrical power, it is possible to recover only up to 35 percent of the available waste energy as power. The surplus heat has to be cooled in a condenser or a cooling tower. This option is attractive if the plant is situated far from consumers who demand heat. When only power is produced, a fully condensing turbine is used. The excess heat is produced at such a low temperature in this condenser that it is not attractive for recovery.
