The riser of a dual ?uidized bed gasi?cation reactor heats bed materials by burning residual char particles coming from gasi?cation part of the reactor. A validated Computational Particle Fluid Dynamic (CPFD) model is applied to simulate combustion of char particles in a riser of dual ?uidized bed gasi?cation reactor in a demonstration plant with 8 MW fuel capacity. The plant is located in Güssing, Austria. The three-dimensional model is used investigate combustion reaction as a function of the bottom, primary and secondary air feed rates. The results show there is a still possibility to improve combustion reaction by optimizing air feed rates, which can maximize the bed material temperature without increasing additional char particles feed.
