Thermogravimetric Analysis on the Combustion Characteristics of Brown Coal Blends

Abstract

The pyrolysis,ignition and burnout characteristics and activation energy of three kinds of brown coal and their blends were studied by thermogravimetric analysis.The experimental results show that the parent coals keep their own individual ignition and carbon burnout characteristics in blend combustion.The pyrolysis characteristics and activation energy of coal blends are decided by the blending rate.Meanwhile,a general combustion parameter S N,which can well indicate the combustion characteristics is proposed in this paper.
