Combustion Kinetic Analysis of Lignite in Different Oxygen Concentration

Abstract:

Combustion behavior of indigenous lignite in oxygen-enriched conditions was investigated by using thermogravimetric analyzer (TGA). Combustion tests were carried out in different oxygen concentration (21%O₂/79%N₂, 30%O₂/70%N₂, 40%O₂/60%N₂, 50%O₂/50%N₂, 60%O₂/40%N₂, 70%O₂/30%N₂). Then get the characteristic temperatures. . The model-fitting mathematical approach was used to evaluated the kinetic triplet (f (α),E,A) through Gorbatchev method. The combustion stages were divided into the early combustion stage and the later combustion stage. The calculation showed that the kinetics parameters higher in the early combustion stage than that in the later combustion stage.
