Process for the utilisation of coalmining dirt with feed of waste products from flue gas purification

摘要

The main application P 3209266.0 relates to a process in which washed dirt and/or milling dirt, by admixture of refuse and waste, is utilised as fuel and availability improver against caking in the thermal, ceramic formation area. In a further development of this process, it is proposed according to the invention to add alkaline earth metal compounds to the ceramic formation process. The alkaline earth metal compounds are composed of residual products of flue gas desulphurisation plants. This addition is used for the ceramic formation process for particle sizes below 10 mm.
