Numerical simulation and experimental on deacidification of flue gas by co-combustion of MSW with coal
Abstract：The structure of the spray drying tower was optimized by installing flow equalization device for deacidification of flue gas produced by co-combustion of MSW with coal.The Fluent software package,RNG k-ε turbulence model,the stochastic model and particle trajectory model were adopted in numerical simulation.The results show that the flue gas is full of the tower and it is prevented from concentrating phenomena on one side of the tower,the mixture of gas and droplet are strengthened,they are all favorable to the absorption of HCl and SO2.When the coburning ratio of MSW and coal increases,the SO2 concentration drops,the HCl concentration increases.With the increasing of the opening area diameter,the cleaning efficiency of SO2 and HCl has increased.The cleaning efficiency has also increased along with the increase of the stoichiometric ratio.With the droplet size of Ca（OH）2 increase the cleaning efficiency of SO2 and HCl has first increased,then decreased.
