Oxy-Kraft recovery boiler - Towards novel integrated green energy parks

Project Details


The objective is to enable the operation of Kraft recovery boilers in oxy-fuel mode, which would allow the integration of several energy-related systems and processes. To do this, several key processes, especially those connected to chemical recovery, will be influenced by the oxy-combustion and need to be assessed. In addition an energy system analysis and techno-economic assessments of integrated green energy processes will be done.
