Economical production of alternative fuels for calciner firing
If you want efficient plants for turning municipal, commercial and industrial waste into fuel, you first have to define the end product. Especially in the single-stage production of fluidised bed fractions for thermal processing in cement kilns/calciners, it is vital that the shredding systems work, for the most part, extremely robustly and reliably around the clock – since one single shredder turns waste into a precious, defined fuel that one is more than entitled to call a ‘product’.
If you look closely at the profitability of the system, the shredder – as an almost standalone solution for this type of processing – becomes the centre of attention. Not only is a great amount of RDF produced during the machine’s lifetime, but costs are also accumulated. In addition to the proportional acquisition costs, wear and tear as well as energy and labour costs have to be considered. These directly influence the system’s profitability. If you total and divide these costs by the amount of the final product produced, you get the costs per ton (€/t). This figure is extremely important...
