Catalytic Or Thermal Reversed Flow Combustion Of Coal Mine Ventilation Air Methane: What Is Better Choice And When?, Krzysztof J. Gosiewski
Catalytic Or Thermal Reversed Flow Combustion Of Coal Mine Ventilation Air Methane: What Is Better Choice And When?, Krzysztof J. Gosiewski
Krzysztof Gosiewski
The paper presents a comparison of the two options of reverse flow reactors destined for the utilization of coal mine ventilation air methane by catalytic (CFRR) or thermal (TFRR) combustion. It has been shown that both solutions have advantages and drawbacks. The use of the catalyst significantly decreases reactor temperature and makes the operation becomes to be autothermal for methane concentrations lower than in TFRR (even as low as over 0.06 vol.%). On the other hand when methane is combusted, particularly if average concentration is higher than ca. 0.4 vol.% the maximum temperature in the reactor appears to be too …
