Municipal Solid Waste (MSW) is a highly heterogenous fuel that sets technical limitations to its incineration process. The combination of high temperature and pressure with harmful waste compounds can cause corrosion and thus render the power plant obsolete. On the other hand, lower temperature and pressure limit the power plant’s power generation capacity. This limitation can be overcome with the help of an external superheater utilizing liquid or gaseous support fuels to enhance the power plant’s energy balance.

The wasteWOIMA® EXT power plant presents all the same benefits of robustness, modularity and scalability as does the standard wasteWOIMA® plant, but with improved power generation capacity. The external superheater improves the power plant’s gross electricity generation by over 50% by allowing the use of higher temperature and pressure than the standard wasteWOIMA® plant. In Combined Heat and Power (CHP) mode the improvement is even higher.
