Oxidation Utilization Technology of VAM in Dafosi Coal Mine

This article elaborates the theory of VAM oxidation which is used to analyze and test the field device. It is shown that the volume of VAM (60 000 m³/h) which is oxidized is large; oxidation efficiency increases with the increasing of VAM concentration; the device shows well at the fluctuation of air volume and VAM concentration; the overheating vapor production and temperature is improved with the increasing of inlet VAM concentration, when the vapor pressure keeps stable.
