Abstract
Abstract
An experimental study was carried out on the concentration of dust in flue gas from the outlet of desulphurization system under the conditions of different ammonia and ozone recharge, When the dust samples were dried at different temperatures, the mass concentration of dust was quite different. Analysis of samples by TG-DSC and XPS, It was concluded that the great change in the mass concentration of soot is mainly due to the influence of the combined denitrification process of SNCR and O3 on the composition of the original flue gas. The formation of Soluble salt was carried by droplets in the flue gas and retained on the filter membrane. It led to a great change in the concentration of dust. The main substances of the soluble salt were carbonic acid, ammonium nitrate and calcium nitrate.
