Assuming a total ventilation air flow rate of 300 m³/s, fifteen 20 m³/s modules would be required, producing a total of up to 11,700 kW_R of cooling. The net power produced was zero between reactor temperatures of 500 and 700 °C at the investigated steam pressures (2.0–7.0 bar). Excess net power was produced at reactor temperatures greater than 700 °C due to the restriction of the inlet VAM temperature to 600 °C (to prevent auto-ignition of the methane upstream of the reactor). At low reactor temperatures the steam flow rate decreased with both reactor temperature and steam pressure but remained constant at reactor temperatures of 750 and 800 °C. The methane abatement plant would be able to operate without an external power supply through the utilisation of the process heat. The plant would produce adequate cooling for a typical gassy underground coal mine in Australia. Such mines are located in the Bowen Basin of Queensland; a region characterised by high virgin rock temperatures with cooling requirements of up to 7000 kW_R.]]> Thu 11 May 2023 13:15:08 AEST ]]>
