Characteristics of self–ignition and smoldering of coal dust layer under inclination conditions
2021, Process Safety and Environmental ProtectionComputational study on self-heating ignition and smouldering spread of coal layers in flat and wedge hot plate configurations
2020, Combustion and FlameCitation Excerpt :The values for stoichiometry and heat of reaction are also obtained from literature. For adsorption, it is reported that 1 kg of coal adsorbs 0.1 kg O2 [30], releasing 2 MJ of heat [29]. For heterogeneous combustion, 1.1 kg of coal reacts with 2.1 kg of oxygen to generate 3.1 kg of gases and 0.1 kg of ash [11,47].
Low temperature heating and oxidation to prevent spontaneous combustion using Powder River Basin coal
2020, Fuel Processing TechnologyCitation Excerpt :At lower temperatures, the accumulation of stable oxidized complexes progressively covers active sites on the surface and leads to a decrease of CO2 production. As the temperature further increasing to 200 °C, the oxidized complexes start to decompose to re-generate sites for low temperature oxidation, as suggested by Kaji [21]. Our surface area measurement supported our assumption.
Proactive inertisation in longwall goaf for coal spontaneous combustion control-A CFD approach
2019, Safety ScienceCitation Excerpt :This model also employs this coal oxidation reaction scheme at low temperature range. Kaji et al. (1987) measured the rates of heat liberation and oxygen consumption due to coal oxidation at low temperature range using coals ranging from subbituminous to anthracite and 300–379 kJ heat evolved per mole of oxygen at steady state was reported. Many works (Edwards, 1990; Salinger et al., 1994; Yuan and Smith, 2009; Zhang et al., 2016a) used 300 kJ/mol oxygen as coal oxidation reaction heat so this model also uses such a value as reaction heat.
