RDF (Refuse derived fuels) is an alternative fuel that has recently been used in the cement industry as a rotary kiln fuel. Generally, RDF is a mixture of different materials which have a certain energy value such as paper, textiles, rubber, plastics, household waste, etc. The quality of RDF varies depending on the source from whichmentionedalternative fuel is obtained. Exactly the quality of RDF has an extremely large impact on the reactivity of cement clinker, which again ultimately has an impact on the quality of the final product, ie cement. In this regard, the use of RDF as an alternative fuel must be treated with extreme caution because the variations in the RDF quality will affectonthe quality of the cement clinker. When it comes to the quality of RDF, we primarily refer to the calorific value of the RDF, however beside mentioned parametershould also pay attention to other parameters such as chlorine, sulfur, mercury, moisture, ash, etc., which also have a crucial effect on the reactivity of the clinker. This paper presents the results of a clinker/cement quality examinationin the case of using of RDF and for the case where RDF was not used. [ABSTRACT FROM AUTHOR] |
