The Eelection Microscope Analysis of Desulphurization with Limestone and Dolomite

Cao Zhang Zhu Meizhu Fang Yilin (Thermal Energy Engineering Research Institute)  
In order to find out the mechanism of desulphuization and mass transfer process,the microstructure of sorbents in bed,the distribution of Calcium and Magnesium and the line-area distribution of sulphur element for a tiny zone in reaction product layer are investigated by the use of the scanning electronic microscope and the wave-energy spcctrum analysis.The reaction thickness and its variation with SO_2 concentration obtained is compared with that measured by thermogravimetric analysis.The relatively audio-visual scientific basis for better understanding the desulphurization mechanism,mass transfer process and their variation regularities are provided.
