摘要: Abstract The reburning of pyrolysis residual is very important in coal fire control and preventing resurgence. This paper researched the reoxidation characteristics lignite using thermogravimetric infrared analysis. macroscopic mass microstructure composition residues were analyzed. critical temperature for reburning. results show that a significant turning point before 450 °C such as variation weight, constant combustible component weight. aliphatic hydrocarbons are gradually reduced due to side chain cracking coal, aromatic increase with degree aromatization structure pyrolysis. residue at ~400 °C easiest reburning, ~450 °C had strongest intensity.
