Abstract

A round robin test, where six ashes (three coal ashes and three bioashes) were analyzed with respect to `fuelspecific` parameters, major and minor elements and trace elements, has been carried out. Thirteen laboratories from Sweden, Finland, Denmark and Norway participated and the purpose of the investigation was to compare and evaluate common methods of analysis for ashes. The standard deviation of the used methods was compared to the precision calculated from the reported reproducability in corresponding standard methods for fuels. The results show that, without taking the significant outliers into account, the precision of the analysis of moisture content, hydrogen, nitrogen, sulfur and the predominant part of major and minor elements was of the order of the corresponding analysis for fuels. The analysis of carbon and calorific value showed a variation somewhat higher than that for fuel analysis, while the results for volatile matter and the tracer elements were considerably less precise. The result for the amount of unburned matter showed significant groupings, not only between the ashes but also between the laboratories. The groupings were explained mainly by the different experimental parameters used during the ashing step. (au) (5 refs., 10 figs., 38 tabs.).
