초록

We have studied that the prediction of desulfurization efficiency by limestone in fluidized-bed coal combustor. The results were presented as follows : Firstly, the bed temperature had a great deal of effect on the desulfurization and the optimum temperature of limestone was 85$0^{\circ}C$~90$0^{\circ}C$. Secondly, as the velocity and temperature increased, $K_{s}$, K and the desulfurization efficiency increased. So, $k_{s}$, $k_{d}$ highly depended on the air velocity and bed temperature, and $k_{s}$, $k_{d}$ were 82.53 mm/sec, 0.0041/sec at 0.2 m/sec, 85$0^{\circ}C$, $k_{s}$, $k_{d}$ were 125.62 mm/sec. 0.00532/sec at 0.3 m/sec, 80$0^{\circ}C$ respectively. And $k_{s}$, $k_{d}$ were 143.78 mm/sec, 0.00568/sec at 0.3 m/sec, 85$0^{\circ}C$. Thirdly, as a result of desulfurization modeling, there was good agreement between theory and experiments as anthracite fraction increased. At 3.0 of optimum Ca/S molar ratio, there was very good agreement between theory and experiments.riments.riments.s.
