- Summary:The combustion of coals in low oxygen concentration, which exists widely in industry combustion, was investigated by the use of thermogravimetry. Experi-mental results show that thermogravity/differential thermogravity/differential scanning calorimetry curves of four studied coals shift to a higher temperature zone in lower oxygen concentration. The ignition temperature is almost constant for each coal and increases with the increased coal rank. The burnout temperature and peak tempera-ture increase with the decreased oxygen concentration. The kinetic parameters were calculated using the Coats-Redfern method for coal combustion in low oxygen concen-tration. The apparent activation energy increases linearly with oxygen concentration,and high rank coal has a high apparent activation energy. An intensive compensation effect exists between the apparent activation energy E and pre-exponential factor A,and the corresponding compensation coefficients are obtained.
