Di Matteo has developed a tubular weigher specifically designed to dose difficult to handle secondary fuels with continuous flow rates. The WeighTUBE® has many benefits compared to gravimetric dosing systems as explained here by Dr Günther Marotz, Dr Luigi Di Matteo and Ulrich Strotkamp of Di Matteo Group Beckum, Germany.
Particularly in the cement industry, recent years have seen the replacement of conventional fossil fuels with alternative fuels. Aside from biomass, sewage sludge, waste tyres, animal meal and municipal wastes, the preferred substitute fuels are industrial wastes with a high calorific value. These powdery, granulated, pelletised fibrous and flocculent secondary fuels derived from quality-controlled industrial wastes are generally known as fluff (gas-entrainable fine materials).
