Investigation on the Performance of Volatile Distributors with Different Configurations under Different Fluidization Regimes

The uniform horizontal distribution of volatiles over the cross section a fluidized bed with purpose to obtain good contact between and materials is key issue improve gas conversion in fuel reactor chemical looping combustion solid fuels. effectiveness volatile distributor (VD) concept on lateral has been investigated under different operational conditions using cold-flow model. Furthermore, performance VD examined configurations holes used distribute volatiles. fluidization regimes, i.e., single bubble regime, only one large formed at time bottom bed, exploding irregular bubbles containing more particles, multiple many small distributed are determined by visual observation riser analysis pressure fluctuations, including frequency analysis. VDs uneven hole arrangements, which have less simulated inlet side larger open area far from inlet, provide even compared equally holes. A flow increase drop distribution. In general, gives regime better regime. However, leakage, leakage VD, should be considered, especially
