Abstract

A laboratory scale thermogravimetric analyser was developed to investigate the combustion characteristics of selected solid fuel(wood) in the highly preheated air. The aims are to introduce in the means of experimental determination of the solid fuel particle characteristics through the combustion process in the environment of highly preheated air. A nearly single particle combustion condition was reproduced in a thermogravimetric analyser and regenerating combustor. For a fuel particle whose characteristic length was a few centimeter, the sub-processes of fuel drying, pyrolysis as well as the combustion of residual carbon were identified. Fluidized environment of carrier gas was selected as the major parameter which affect the combustion process.
