Analysis and characterisation of solid fuels and ash

Clean Energy through its collaboration with the partner Institute CERTH /CPERI offers a complete range of fuel characterization of solid biofuels and refuse-derived fuels based on the latest European standards arising from Technical Committees CEN 335 and CEN 343 respectively.

Thus, end-users can have a thorough understanding of the combustion properties of the fuels that they consider for their application and make informed choices on the proper utilization technology.

Fuel characterization

  • Analysis of calorific value
  • Proximate (moisture, ash, volatiles, fixed carbon) and Ultimate analysis (C, N, H, S, Cl)
  • Analysis of physical properties of pellets such as durability (DU), bulk and particle density (BD & PD)
  • Heavy metals concentration (major, minor elements)

An integrated set of analyses for combustion & gasification by-products (such as fly ash, bottom ash, FGD gypsum, etc) can be performed and suggestions on the environmental impact and the optimum utilization paths are offered by leading scientists in the field.

  • Determination of chemical composition, trace elements characterization and leachability, including As and Hg, by means of Atomic Absorption Spectroscopy (AAS), Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES), and X-Ray Fluorescence (XRF) Spectroscopy
  • Determination of mineralogy and morphology, by means of X-Ray Diffraction (XRD) Spectroscopy and Scanning Electron Microscopy (SEM), respectively
  • Determination of ash fusion temperatures by means of LECO Analyzer and Particle Size Distribution (PSD), by means of MalVern analysis.

Based on the above, predictions on slagging/erosion/corrosion potential of the respective fuels and co-firing mixtures are also made.
