Processing route for ready-to-fire alternative fuels derived from waste fractions

Now, with the aid of simple technology for reducing the contaminant contents of all substitute-fuel fractions, an online conditioning process can be installed upstream of the kiln, simultaneously stabilizing the control system.

1 Introduction

For a long time now, alternative fuels in the form of RDF (refuse-derived fuel), more often referred to as SRF (solid-recovered/specified-recovered fuel), stemming from processed municipal and industrial/commercial waste have been in use as supplementary sources of energy in the cement industry.

Household and industrial/commercial waste volumes are treated, inter alia, according to the following basic processing operations:

mechanical conditioning and fractionation


thermal drying

mechanical/physical fractionation

At diverse European waste treatment facilities, a...
