abstract = "Low-density peats from many countries have long been studied by
many authors. They are mostly forest and moss peats. Different
peat types, from different locations in the world, may present
degradation behavior that differs significantly. Bulk density,
which is one the most important physical parameters governing the
smoldering dynamics of solid fuels, varies among countries'
peatlands. This work compares experimental data for low (200 kg
m(-3)) and high (450 kg m(-3)) bulk density peat smoldering in a
test bench. Peat sam-ples with different densities, organic matter
contents, and particle sizes were considered in this work. The
physicochemical characterization included ultimate analysis, ash
composition, the density of the solid, and thermogravimetric and
differential thermogravimetric analysis. The influences of the
organic matter content, as well as the bulk surface area to volume
ratio on peat burning, are also discussed. It is showed that, for
the same organic matter and bulk surface area to volume ratio, the
high bulk density peat burning rate is as low as one-third of the
low bulk density peat burning rate. Once the High Heating Value of
both peats is found similar, this lower burning rate is related to
chemical kinetics, which shows higher oxidation temperature,
around 500 degrees C for the high bulk density peat, and 300
degrees C for the low bulk density peat. For the high bulk density
peat, the higher the bulk surface area to volume ratio the higher
both horizontal and vertical smoldering spread rates.",
