  1. QUO VADIS WP 7 - Biological ParametersProf. Dr.-Ing. Sabine Flamme14. December 2006, Ispra

  2. Tasks • Carry out biomass content determination using different methods of the Final Draft of the prCEN/TS 15440 „Solid recovered fuels - Methods for the determination of biomass content“. • Manual Sorting of SRF material and determination of the biomass content in percent by weight • Selective dissolution tests with different (reference) SRF materials, Determination of the biomass content in • percent by weight • percent by calorific value • percent by total organic carbon content

  3. Status Quo of the Work Package • Comparison of Manual sorting method and selective dissolution test with Solid recovered fuel samples from municipal solid waste are finished • Calculation of the biomass content with manual sorting as defined in the CEN Draft / with variances in the classification • Determination of water content, TC, ignition lost, calorific value of single fractions • Comparison with results of the selective dissolution test in percent by weight / percent by calorific value / percent by total carbon content • Determination of the biomass content of different SRF-Materials has continued • First samples for the homogeneity tests for the round robin material arrived • Homogeneity will be tested on a mass-related base   

  4. Working plan for further investigations - Summary • Ruggedness tests • SRF-Material (WP 4): • Soft pellets - Hard pellets - SRF-Samples • different grain sizes (2 mm, 1 mm, 0,5 mm) • Reductionistic Method - shall be under examination by using the data that were necessary for the converted SRF-Sample • Additional Material: Tyre Samples< 1 mm • Round Robin • Materials from IRMM, homogeneity tests for biomass content • Same laboratories as for the chemical parameters     ()  

  5. Intermediate results - Selective dissolution test (1)Biomass content in Hard Pellets

  6. Intermediate results - Selective dissolution test (2)Biomass related carbon content in Hard Pellets

  7. Intermediate results - Selective dissolution test (3)Calorific value related biomass content in Hard Pellets

  8. Intermediate Results: Selective dissolution test (4)

  9. Intermediate Results - Résumé • Selective dissolution test • Remaining residue is clearly less homogeneous than the crushed sample before selective dissolution • Mass-based biomass fraction  all in all good results • Carbon-based biomass fraction  • Result of the TC-determination (especially of the residue) has a great influence on the result of the biomass related TC-content  appropriate accuracy is to demand (depending on the TC-analyser higher amounts of sample material or appropriate repeated determinations are necessary) • Calorific value based biomass fraction  • calorific value has to be determined with an appropriate accuracy (especially of the residue) • to generate sufficient residue for the determination of the calorific value, often means to dissolute higher amount of sample material (great expenditure)
