Ash and slag waste (ASW) is a finely dispersed mineral material resulting from the combustion of brown and hard coal at thermal power plants. The involvement of ash and slag waste in industrial circulation is one of the effective ways to solve the issue of energy and resource saving. Utilization of ash and slag waste in industrial production will provide a solution to the environmental problem of environmental pollution by industrial waste - technogenic fine dust and harmful effluents by gradually reducing the rat...

Among the existing methods of processing waste from coal-fired thermal power plants, little attention is paid to the problem of ash disposal with variable composition. During the combustion of coals, various chemical reactions occur as part of their mineral part, resulting in the formation of a new technogenic raw material that differs from natural raw materials in chemical and phase composition and has other technological properties. Using the example of a coal-fired power plant burning coals from six different d...
