摘要	Combustion characteristics and kinetics of partial gasified coal char (PGC-char) were investigated in this article. Two-stage distributed activation energy model (TS-DAEM) and simple model were used to model the combustion kinetics. The experimental results showed that the combustion characteristics of PGC-chars varied with coal types and percentage of gasification. Modeling results showed that TS-DAEM could suitably describe the combustion of PGC-char. The activation energy and preexponential factor increased with the increasing of PGC-char gasification percentage, but the percent of high reactivity part decreased. This indicated that the difficulty reactive part in the partial gasified coal char became more and more with the gasification conversion. However, simple model wasn't fit to describe the combustion of PGC-char, especially for PGC-chars with obvious second peak in combustion DTG curves.
