摘要
研究了两种烟煤和玉米淀粉、石权子粉粉尘层的反应动力学参数。实验是采用热重分析方法在氧浓度分别为0、2％、8％、20％、50％和100％及层流条件下进行的．并用气相色谱在不同的温度范田内对粉样的气相成分进行了分析，依据实验结果求出上述4种粉尘的氧化、热解动力学参数并对粉尘层氧化某些机理作了描述。
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.
