The
aim of the study was the evaluation and comparison of energy potential of
briquettes and pellets produced from the maize straw and woody biomass based on various
diameters of pellets. By experimental measurements a calorific value and ash content was
obser
ved. Calorific value was measured by laboratory calorimeter IKA C 6000 (IKA® Works,
Inc., USA) and laboratory combustion chamber Lindberg/Blue M (Thermo Fisher Scientific, Inc.,
USA). Individual calorific values and ash content was observed and subsequentl
y confronted to
obtain differences with replication. The analysis showed that calorific value of pellets with
diameter 6 mm ranged from 16.99 MJ

to 17.80

. Calorific value of pellets with 8
mm
diameter ranged from 16.63

briquettes ranged from 14.99

. Further analysis showed that ash content
of samples varied as well and it’s even affected by diameter of pellets. While ash content of pellets
with diameter 6 mm
was observed as 4.9% of total volume in case of pellets with 8
mm it was
observed at value 5.5%. Briquettes produced from maize straw have ash content at value 5.4%.
In contrary, ash content of woody biomass was significantly higher, 11% of volume, specifi
cally.
At the basis of observed parameters it can be concluded that maize straw densified in form of
briquettes and pellets have a great energy potential which is comparable and competitive with
currently used materials for production of briquettes and pel
lets.
