Background: VTT have conducted extensive research into fluidized bed combustion, fuel characterization and oxy-combustion. Chemical looping research was started a few years ago to broaden this knowledge to new areas of technology. Tests with various oxygen carriers have been carried out using thermogravimetry and a bench scale laboratory device. Initial tests and proof of concept: The first cold model of a solid recycle device was constructed in 2011. Initial tests showed that in CLC applications solid flow may be controlled with fluidization at a double exit loop-seal.The new reactor system concept has been designed based on the model simulations and scaling laws. The cold model platform has been constructed in order to further develop the concept. The cold model has been commissioned and hydrodynamic tests started.
