Methods for identifying the material-recyclable share of SRF during co-processing in the cement industry

摘要

Solid Recovered Fuels (SRF) include non-combustible mineral components (e.g. CaCO , SiO , Al O ) that are required as raw materials for producing clinker and are completely incorporated into the clinker during the thermal recovery of SRF. This paper discusses simple and practicable ways of finding the relative amount of SRF that may be utilised as raw material (given as the recycling index). For this purpose, the entire mineral content of SRF was determined as the ash content and its main components were identified using different analytical methods.
