Combustion behavior of xylite/lignite mixtures

摘要: Abstract The behavior and the kinetics in nitrogen air of two low-rank coals (lignite xylite) their blends, as well compatibility component blends were evaluated, an effort for rational use poor coals. experiments conducted a thermobalance system, at non-isothermal heating conditions, with rates 20 100 °C/min, temperature range 25–850 °C. Material particle size was −100 μm. A first-order parallel independent reactions model power law fitted successfully rate data pyrolysis combustion, respectively. Activation energy values reaction orders ranged from 23 to 182 kJ/mol 0.8 2 did not affect kinetic parameters considerably, however when this increased shifted higher temperatures greater. lignite/xylite could be sufficiently predicted, based on individual fuels. However, true case char combustion. Blending lignite xylite, any proportion, seemed cause some interactions between air.
