Characterization of a pressurized feeder for biomass injection into gas-solid systems

Injection of biomass powders into multiphase reactors is a challenging task that may impact the process yield and limit operation due to feeder’s blockage or unstable flow. A horizontal pressurized gas-solid feeder characterized in this study inject batch different diameters cold-flow model operating under single phase, fixed fluidized regimes. The hydrodynamics injection line investigated for conditions, using fast camera with acquisition rate 3000 images/s. Stable injections are performed wide range solids fluxes, solid concentration flow conditions. map produced, phenomena produce difficulty stable discussed. Ultimately, type injector useful feeding lab-scale mixing kinetic studies might be also scaled-up treating waste pilot-to-industrial scale semi-continuous operations.
