Experiment of Sheng Li Lignite Combustion Kinetics under Oxygen-Enriched Conditions

Article Preview

Abstract:

The characteristics of Sheng Li (China) Lignite combustion under oxygen-enriched conditions were studied by thermogravimetric analysis , including TGDTG and DTA. Experiments on lignite combustion were carried out under four kinds of oxygen-enriched conditions (O2/N2 mixture atmospheres) and with a heating rate of 10°C/min. The experiments of working temperature range was 20°C-900°C. The combustion process, regarded as the first order reaction, was analyzed through the Gorbachev kinetic equation participants, which gained the conclusion that Sheng Li lignite combustion reaction shift to low temperature zone and kinetic parameters of combustion increase gradually when oxygen concentration increase.
