The deposition prediction indicates that coal dust particles (50-212 µm) could be deposited in the VAM capture duct within 55 m to 217 m depending on the particles size, particle velocity. MIE tests for three size ranges of coal dust particles were undertaken. Results showed that the MIE of coal dust particles in the 0-74 µm size range, ignited in a range of 100-300 mJ. However, for the coal dust particles in the size range from 74-125 µm and 125-212 µm the MIE measured was in the range of 300-1000 mJ. The ignition coal dust concentration was varied between 150 g.m^-3 to 1500 g.m^-3 for the tests.]]> Thu 31 May 2018 09:12:19 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32401 -1 at 4.0 m from the ignition source) than inside the vessel (173 bar.s^-1) for 9.5% methane.]]> Thu 31 May 2018 09:12:14 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32404 Thu 31 May 2018 09:12:12 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32405 Thu 31 May 2018 09:12:08 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32402 Thu 31 May 2018 09:12:07 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32400 -1 for the range of methane mixtures exploded. The severity of the explosions increased with increasing igniter energy. The maximum pressure rise rate increased from 83 bar.s ^-1 for 1 kJ igniter to 90 bar.s^-1 for 2 kJ igniter, to 155 bar.s^-1 for 5 kJ igniter and to 222 bar.s^-1 for 10 kJ igniter. The severity of the explosions increased with increased coal dust concentration. At 2.5% methane-air mixture, the pressure rise rate increased from 4 bar.s^-1 to 114 bar.s^-1 when the coal dust concentration increased from 50 g.m^-3 to 100 g.m^-3, respectively.]]> Thu 31 May 2018 09:05:09 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32657 Thu 05 Jul 2018 10:55:14 AEST ]]>
