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.

This article presents the tests of fly ash properties which originated from co-combustion. The ash samples for testing came from Polish combined heat and power plants co-firing different types of biomass with hard coal in pulverized and fluidized beds. For comparison purposes, the properties of fly ash from coal combustion also were examined. Measured properties include grain composition, specific density, bulk density, and grain shape. Statistical analysis of results did not demonstrate the influence of biomass on the ash properties.
