Properties of energy by-products after biomass combustion

Popis výsledku v původním jazyce

This article deals with the characterization of ash produced by biomass combustion (BMA) as well as by co-combustion of coal with biomass (CC-BMA), produced by large power plants in the Czech Republic. Chemical, physical and mechanical properties of the ashes and their mixtures were determined by several test methods, according to the valid legislation. It was found that the properties of BMA and CC-BMA differ significantly. These properties are influenced by the type of material burned, the method of combustion and the place of sampling (fly ash x bottom ash). In addition, it can be concluded, none of the BMA and CC-BMA samples met all the requirements for chemical composition according to EN 450-1 standard method. The relationship between water consumption and the mean particle size of the BMA and CC-BMA was shown. It can be state that the requirement for the initial and final setting time and soundness was met by all pastes according to EN 450-1. None of the sample meets the requirement of the standard in terms of the activity index values which range of 50 - 70 %.
