The Hafner “Waste To Energy” Plants are essentially based on four main categories:
Depending on the waste heat value, two different combustion technologies are used. Grate firing with an integrated steam boiler plant is used for low to medium-calorific waste. And for highly calorific waste, a rotary kiln with afterburning chamber and waste heat boiler is used.
The plant technology is designed to use upwards of 65% of the thermal energy (R1 – as defined according to Annex II of EU DIRECTIVE 2008/98/EC on Waste) including power generation, district heating or cooling and process steam
In the tradition of conventional simple flue gas cleaning, Hafner relies on a completely dry flue gas cleaning process with double flue gas filtration for increased dust retention and more efficient pollutant minimization. The achieved emission values are thus far below the EU limit values.
From the slag residues of combustion, valuable materials are recovered by further treatments and different selection processes.
