Abstract:

The inter-connected fluidized bed (IFB) cold model with four 10 cm x 10 cm compartments was built to establish operational parameters and provide the information for future commercial design of an IFB gasification system. Glass beads, dolomite and limestone were employed as bed materials to investigate the effects of those materials. The effects of the particle weight, gas velocity, orifice diameter, and orifice height on the circulation rate of solids (CRS) in the IFB were investigated. The preliminary results show that the CRS increases with increasing gas velocity of the lean bed, bed weight and orifice diameter. The diameter of limestone decreases during the operation and the value changes from 0.2483 mm in the beginning to the 0.1799 mm after 30 minutes. The diameter of dolomite keeps near constant value of 0.18 mm during the operation. It shows that dolomite is better than limestone if the CO2 capture sorbent is require to cycle use. The hot model will be designed and commissioned based on the present results to carry out the further investigation.
