EFFICIENCY INCREASE OF A WASTE-TO-ENERGY POWER PLANT

This technical project focuses on increasing the energy efficiency of the waste-to-energy facility at Kehrichtverbrennungsanlage Horgen (Zürich) by identifying and optimizing subsystems where significant thermal energy is currently wasted. Key areas analyzed include the flue gas exhaust system, air-cooled condenser (ACC), turbine bleeds, and bottom ash extractor. Through thermal performance evaluations, process data analysis, and feasibility studies, the project proposes engineering solutions such as enhanced flue gas heat recovery, steam-water heat exchanger integration for district heating, and steam parameter optimization at the turbine. These measures aim to utilize low-grade waste heat more effectively, thereby improving the plant’s overall thermal efficiency and reducing energy losses to the environment.
