  • the rdf srf torrefaction an effect of temperature on characterization of the product carbonized Refuse Derived Fuel

    Co-Authors: Andrzej Bialowiec, Jakub Pulka, Piotr Manczarski, Pawel Stepien, Janusz Golaszewski
    Abstract:

    Abstract The influence of Refuse Derived Fuel (RDF)/Solid Recovery Fuel (SRF) torrefaction temperature on product characteristic was investigated. RDF/SRF thermal treatment experiment was conducted with 1-h residence time, under given temperatures: 200, 220, 240, 260, 280 and 300 °C. Sawdust was used as reference material. The following parameters of torrefaction char from sawdust and Carbonized Refuse Derived Fuel (CRDF) from RDF/SRF were measured: moisture, calorific value, ash content, volatile compounds and sulfur content. Sawdust biochar was confirmed as a good quality solid Fuel, due to significant Fuel property increase. The study also indicated that RDF torrefaction reduced moisture significantly from 22.9% to 1.4% and therefore increased lower heating value (LHV) from 19.6 to 25.3 MJ/kg. Results suggest that RDF torrefaction may be a good method for increasing attractiveness of RDF as an energy source, and it could help unify RDF properties on the market.

  • pyrolysis and gasification studies of model Refuse Derived Fuel rdf using thermogravimetric analysis

    Abstract:

    Abstract Processing Municipal Solid Waste (MSW) into a Refuse Derived Fuel (RDF) reduces experimental variability and improves handling. This study analyzes the pyrolysis of individual components to define the model components that mimic real RDF. Size reduction and effective mixing of nine components of model RDF composition allow for reproducible results in lab scale experiments. Selected individual components as well as the model RDF composite are converted by pyrolysis and gasification at 800 °C with a 20 K/min heating rate. The pyrolysis results show that the decomposition profile, product yields, heat of decomposition, and gas composition of the model RDF can be predicted by adding the corresponding values of the individual components in the required proportions. The inorganic content of the individual component chars is found to have a profound effect on the gasification reactivities. Potassium and calcium have the largest catalytic effect during gasification, while silicon and phosphorous inhibit gasification. Potassium mobility and redistribution from orange peels in the model RDF to the other components is determined to be chiefly responsible for the synergistic gasification profile of the char. Furthermore, synergy is observed at different particle size ranges (

  • the proof of the concept of application of pelletization for mitigation of volatile organic compounds emissions from carbonized Refuse Derived Fuel
    Materials, 2019

    Abstract:

    Waste can be effectively reused through the production of carbonized Refuse-Derived Fuel (CRDF) that enables further energy recovery. Developing cleaner production of CRDF requires consideration of practical issues of storage and handling. Thus, it needs to be ensured that CRDF does not pose an excessive risk to humans and the ecosystem. Very few studies indicate a wide variety of volatile organic compounds (VOCs) are present in CRDF, some of which are toxic. During handling, storage, transportation, and use of VOC-rich CRDF, workers and end-users could be exposed to emissions that could pose a health and safety hazard. Our recent study shows that CRDF densification via pelletization can increase the efficiency of storage and transportation. Thus, the following research question was identified: can pelletization mitigate VOCs emissions from CRDF during storage? Preliminary research aiming at the determination of the influence of CRDF pelletization on VOCs emission during storage was completed to address this question. The VOCs emissions from two types of CRDF: ground (loose, torrefied Refuse-Derived Fuel (RDF)) and pelletized, were measured. Pelletization reduced the VOCs emissions potential during the four-day storage by ~86%, in comparison with ground CRDF. Mitigation of VOCs emissions from densified CRDF is feasible, and research is warranted to understand the influence of structural modification on VOCs emission kinetics, and possibilities of scaling up this solution into the practice of cleaner storage and transportation of CRDF.

  • the rdf srf torrefaction an effect of temperature on characterization of the product carbonized Refuse Derived Fuel
    Waste Management, 2017

    Abstract:

    Abstract The influence of Refuse Derived Fuel (RDF)/Solid Recovery Fuel (SRF) torrefaction temperature on product characteristic was investigated. RDF/SRF thermal treatment experiment was conducted with 1-h residence time, under given temperatures: 200, 220, 240, 260, 280 and 300 °C. Sawdust was used as reference material. The following parameters of torrefaction char from sawdust and Carbonized Refuse Derived Fuel (CRDF) from RDF/SRF were measured: moisture, calorific value, ash content, volatile compounds and sulfur content. Sawdust biochar was confirmed as a good quality solid Fuel, due to significant Fuel property increase. The study also indicated that RDF torrefaction reduced moisture significantly from 22.9% to 1.4% and therefore increased lower heating value (LHV) from 19.6 to 25.3 MJ/kg. Results suggest that RDF torrefaction may be a good method for increasing attractiveness of RDF as an energy source, and it could help unify RDF properties on the market.
