| Abstract: | The mathematical model for the gas-solid heat transfer in cocurrent downflow circulating fluidized bed(CDCFB)reactor was proposed in this paper. Experiments of stable heat transfer were conducted for measuring axial particle temperature distribution in CDCFB reactor. The particle transfer coefficient of gas-solid at axial section and apparent heat transfer coefficient of gas-solid, as model parameter, were obtained from experimental data by using the Matlab software for nonlinear regression. |
| Keywords: | downflow circulating fluidized bed gas-solid heat transfer model |
