This report discusses various topics with respect to coal ashes. The composition and characteristics of fly-ash and bottom-ash are described. The fouling of boilerinstallations by mineral matter in the coal is discussed. Furthermore a comparison is made between the ash from direct combustion and from gasification with respect to quality and the amount produced. The impact of ashes on the environment is taken into account. Finally transportation and dumping of ashes and the potential useful applications are treated a quantative estimate of the amount of ash that could be used productively is given. A major conclusion is that all efforts should be directed towards the use of ash instead of dumping.
