Abstract
In this paper we describe and test the use of a thermogravimetric technique for measuring the ignition temperatures of thin layers and beds of coal particles, and we report the results of such measurements on a South African coal, a Polish coal and two chars. The technique is to compare weight-temperature curves in air and inert (N2) atmospheres in order to evaluate the ignition temperature; the results are used to test the existing theory and to obtain kinetic constants for the reactions.Keywords
