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

摘要

The characteristics of Sheng Li(China) Lignite combustion under oxygen-enriched conditions were studied by thermogravimetric analysis, including TG,DTG and DTA. Experiments on lignite combustion were carried out under four kinds of oxygen-enriched conditions(O_2/N_2 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 ncrease gradually when oxygen concentration increase.
