Investigation of Lignite Combustion Characteristics with Thermal Analysis

Abstract:

Combustion characteristics of three types of lignite (coming from Indonesia, Ximeng, Hami), and a bituminous coal from Shenfu were studied by thermogravimetric analysis (TGA). Combustion parameters including characteristic temperatures, maximum rate of combustion, combustion performance index and activation energy of samples were analyzed. Kinetic parameters of samples were calculated using Jander model. The results showed that the characteristic temperatures of lignite samples are lower than that of bituminous coal. Indonesian lignite has the best combustion performance and the lowest activation energy. It indicates that high quality lignite such as Indonesian lignite has good combustion performance, even better than some bituminous coal, which makes it possible to use lignite by bulk combustion.
