Exploration on the Combustion and Utilization of Coal Mine Methane with Low Concentration

In this paper, the current research status of combustion and oxidation technology used for coal mine methane with low concentrations and ventilation air methane (VAM) of our research team are summarized and partial research results has been listed and displayed. Using filtration combustion experimental units, the typical flame structure and temperature profiles of porous burner were obtained. By the self-designed VAM oxidation apparatus, the axial temperature profiles in the experimental unit with VAM reciprocating flow were measured. The conception of combustion and energy utilization system used for coal mine methane with low concentration were organized which coordinated effectively the reasonable matching of different devices. The system avoided effectively the low-density energies losses.
