APPLICATION OF PHASE CHANGE MATERIAL for IMPROVED EFFICIENCY IN WASTE-to-ENERGY PLANTS
Supported by: National Environmental Agency, 2017-2019
Description
-
Traditional steam generation boilers suffer from thermal power fluctuation due to the waste combustion which is characterized by a high variability in net calorific value. This leads to a few technical issues which limit the maximum net electric efficiency of WtE plants: the limits on the maximum steam temperature and the fluctuation in steam production

The proposed technology intends to replace the existing water-wall technology with technology based on PCM
-
To increase the electrical efficiency of WtE plants by developing a modular and cost-effective PCM-wall technology
-
Increase the efficiency of the Waste to Energy plants beyond 34% with a simple retrofitting solution
