NUMERICAL SIMULATION OF DESULFURIZATION CHARACTERISTICS IN CFB DESULFURIZATION TOWER WITH BYPASS
摘要
Abstract
Momentum, energy and composition equations of a new CFB desulfurization tower with gas bypass are solved by standard k-ε model, DPM, species transport and finite-rate chemistry model, and numerical simulation results agree well with the experimental results. The characteristics of desulfurization and flow resistance of two desulfurization towers are researched by numerical simulation, and the influence of gas velocity and circulation rate to desulfurization efficiency of bypassing desulfurization tower is also researched. The results show that both desulfurization and flow resistance characteristics of bypassing desulfurization tower are better than those of non-bypassing desulfurization tower. When gas velocity increases, desulfurization efficiency of bypassing desulfurization tower slightly increases and then decreases; desulfurization efficiency increases clearly when circulation rate of desulfurizing agent increases from 20 to 50, but it only has a slight increase when circulation rate is more than 50.关键词
