Abstract: In this paper, the combustion characteristics and kinetic parameters of bituminous coal and anthracite blended coals at different ratios were analyzed on a high temperature thermogravimetric analyzer. The combustion characteristic parameters such as ignition temperature, burnout temperature and comprehensive combustion characteristic index of blended coals with different blending ratios are analyzed. The reaction kinetics is calculated and analyzed. The experimental results show that with the proportion of anthracite to bituminous coal is increasing, TG and DTG curves moved to high temperature region, There are two peaks in the DTG curve of mixed coals with different mixing ratio,mixed coal ignition temperature and burnout temperature increased gradually, mixed coal at high temperature the activation energy is always higher than that of low temperature, it indicates that volatile branch will be released at low temperature and release a large amount of heat, which will improve the combustion environment of fixed carbon and promote the combustion of fixed carbon. Bituminous coal and anthracite blended coals have better combustion performance and performance at low temperature.

Keywords: Blended Coal, Ratio, Combustion Characteristics, Kinetic Parameters
