영문 초록

We have studied that the prediction of desulfurization efficiency by limestone in fluidized-bcd 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 850℃-900℃. Secondly. as the velocity and temperature increased. k. K and the desulfunzation efficiency increased. So. Ks Kd highly depended on the air velocity and bed temperature. and Ks Kd were 82.53 mm/sec 0.0041/sec at 0.2 m/sec. 850℃. Ks Kd were 125.62 mm/sec. 0.00532/sec at 0.3 m/sec. 800℃ respectively. And Ks Kd were 143.78 mm/sec. 0.OO568/sec at 0.3 m/sec. 850 C. Thirdly. as a result of desulfurization modeling. there was good agreement between theory and experiments as anthracite fraction inereased. At 3.0 of optimum Ca/S molar ratio. there was very good agreement between theory and experiments.
