hermogravimetric analysis (TGA) has been largely used to
characterize the thermal decomposition of coal and, more recently,
to characterize biomass fuels [14,15] and their co-combustion with
coal [16,17]. The advantage of TGA is that provides a rapid assessment
of the fuel value, the temperatures at which combustion
starts and ends and other characteristics such as maximum reactivity
temperature or total combustion time. For any fuel or blend,
the necessary information to estimate combustion efficiency, residence
time, excess air, boiler design, etc., may be obtained by TGA
in an easy way. Furthermore, TGA has proved to provide a way of
rapidly assessing the kinetics of thermally induced reaction such as
the combustion of carbonaceous materials
