This work investigates the lateral mixing process of fuel in a cold flow model of a fluidized-bed gasification chamber in an indirect gasification system. The bed has a significant cross-flow of bulk solids and the fuel mixing is investigated with respect to how operational conditions (fluidization velocity and solids circulation rate) and the fuel-feed location influence the fuel residence time in the gasification chamber. Fluidization velocity and fuel feeding location are found to influence fuel residence time the most, whereas solids circulation rate has no significant effect at the conditions tested.
