A flare also would not be a good fit for the Ventilation Air Methane application due to the significant supplemental fuel/heat required to maintain destruction efficiency, which results in a much higher operating cost.
In the US, mines typically operate at methane concentrations ranging anywhere from 0.3% to 0.4%, and at concentrations above 0.3% oxidation systems can generate a substantial amount of excess heat. In low methane concentrations, a supplemental Coal Mine Methane (CMM) injection can help to increase methane concentration levels in the feed stream to the RTO.
Air Clear’s RTOs are flexible enough to handle the large volume of air coming from your mine shafts even when relatively low concentration streams are present, all while remaining capable of handling spikes in methane emission and flow.
