The character of indigenous lignite was measured by proximate analysis, ultimate analysis, coal ash analysis, coal true relative density, specific area.et al. The results showed that the internal moisture content is 8-9%, volat ile matter content is more than 45%, the oxygen content is above 20% while the sulphur content less than 0.5%.The main ash content is SiO 2 and Al 2 O 3 , ash fusion point is above 1200 degree centigrade. The calorific value is between 12∼19MJ/kg. Macropore and mesopore is the pattern in the lignite.
