Abstract:
The Horizon Europe project CBE4I focuses on developing an innovative, fuel-flexible biomass conversion technology for highly energy-efficient, near-zero-emission, and zero-waste process heat supply, tailored for flexible implementation in industrial settings. The goal of achieving near-zero emissions is addressed through a combination of technologies: a fixed-bed updraft gasifier with virtually zero dust emissions, a directly coupled, multi-stage gas burner capable of achieving near-zero CO and organic gaseous compound (OGC) emissions and the integration of a novel three-way catalyst (TWC) system based on wire-mesh substrates within the burner to reduce NO. emissions by approximately 85%. To support this, a burner design optimized for effective TWC integration has been developed based on CFD simulations. Various TWC configurations were tested in a laboratory reactor, and the most suitable option was selected for pilot-scale validation at a test facility constructed as part of the project. These tests are ongoing.
