ABSTRACT
This article describes the chemical properties of the resulting ash from co-combustion of hard coal with
biomass. Biomass consisted of sunflower husks, bran grains, and forest biomass. To test the fly ash we sampled
from different types of boilers: pulverized, fluidized, and in the case of pulverized boilers ash samples
with and without desulfurization products were tested. The results were compared with the properties of ash
without co-combustion, which were obtained in the same type of boilers. Chemical and mineralogical compositions
were determined and thermal analysis was carried out as well. Studies showed no effect of co-combustion
biomass with coal on the tested properties of obtained ash.
