Study on Reaction Kinetics of Several Types of Dust Layers

He Dongbo Shengjun Deng Xufan (Industrial Explosion Protection Institute(IEPI), Northeastern University)  
1 A study on reaction kinetics of maize, lycopodium and two kinds of bituminous dust layers are presented. The experiments are conducted using thermogravimetric analysis under different temperature, oxygen content of 0.2 %, 8 %, 20 %, 50 % and 100 % respectively and lami-nar flow condition. The vapor composition of the samples under different temperature are analyzed by means of an infrared. As results of experiments, the models of oxidation and thermodecom-position of the four types of dust layers are established and some of mechanism of oxidation of dust layers are described.
