Density-refused-derived fuel

Although both are graded solid fuels of broadly similar bulk densities there are significant differences in respect of other properties. The densified refuse derived fuel has a lower calorific value, higher ash content and lower ash fusion temperature. The major differences are the much higher proportion of volatile matter in the dRDF coupled with a very much lower value for the fixed carbon. These differences are likely to be sufficient to render not only the combustion properties different, but also the deposition from the respective flue gases.
