This article presents the results of a pilot plant study on fine coal processing to
produce alternative fuel. Fine-grained waste generated in the processing plant of a
coal-processing plant in eastern Poland (Lublin Coal Basin) was used to obtain
briquettes using the roll press briquetting method. The study included material
homogenization, the selection of suitable parameters for the roll press unit, and
an analysis of briquette quality. Strength and waterproof testing of briquettes and
a study of the heat of combustion as well as ash and dust emissions were performed.
Based on the results, the production processes were developed for three types of
coal-based fuel briquettes with additional components, such as potato starch, mol-
asses, and wood biomass. Briquettes made with starch met the minimum quality
requirements, but use of a cheaper binder (molasses) did not provide good quality
briquettes. The addition of biomass in an amount not exceeding 20 % by weight
did not significantly affect the pollution emissions in the combustion tests. The fuel
obtained had a suitably high-energy value (22–24MJ kg 1 ) and may be used as an
alternative fuel for combustion in industrial and domestic boilers
