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.
