Te majority of WtE plants use a steam Rankine cycle: hot flue gas passes through a hett recovery steam generator (HRSG) producing superheated steam that cards a turbine generator. Trends in this area included:

Organizacja Rankine Cycle (ORC) i Low- Temperature Heat Recovery

For slaler-scale spalarnie or those with fluticating heet loads, ORC systems using organic working fluids (np., silicone oil, pentane) can generate electricity from lower-temperatur flue gas (200- 400 ° C).

Pre-Incineration Anaerobic Digestion

Feeding sludge the volume of material to burned dighester before splaremation reduces the organic fraction by 40- 60%, lowering the volume of material to burned increaming it calorific value.
