Despite many advantages of the u tilization of biomass a s a r enewable energy source, certain
bot t lenecks during biomass plant operation can be identified. Div ersity in space, periodicity of
biomass collection and non-uniform material characteristics a r e issues r elated to decr easing
efficiency of logistics and fu el manipulation which can a lso cause economic problems with
biomass collection, transport, and storage. Since biomass is an especially reactive fuel, this has
r a ised concerns ov er its safe handling and utilization. Fires, and sometimes explosions, are a risk
du r ing all stages of fuel production a s well a s during handling and utilization of the product. This
paper presents a nov el method for assessing ignition risk and prov ides a ranking of the relative
r isk of ignition of biomass fu els. Tests within this method include physical and chemical
properties of biomass, thermal analysis (TA) measurements, and the calculation procedure steps
which were ma...de using characteristic temperatures from thermogravimetry (TG) recordings. The
TG r esults were used for the determination of the tangent slope of the mass loss rate curves in the
dev olatilization zone at considered heating rates for all tested samples. Linear interpolation of the
da ta obtained by tangent slope analysis and used heating rates may prov ide a unique straight line
for ea ch sample in the ignition testing. TG index of spontaneous ignition (TG spi) is obtained for all
samples based on a newly established formula. By v arying gradient of linear dependence of selfhea
ting coefficient against reference temperatures (Tref,i), mass and heat transfer limitations for
v arious biomasses were discussed. The proposed method is accurate as well as relatively simple
and quick, enabling determination of data necessary for the design and application of appropriate
mea su r es to r edu ce fir e and explosion ha za rds r ela ted to the oper a t ion of bioma ss.
