“…Lower moisture and ash contents were found when compared with typical European RDF. According to the European standard of RDF (CEN-TC 343), the samples could be classified as a middle-heating value fuel [10]. The raw material came in block form and was ground to granules with a diameter of 0.64 mm before gasification.…”

“…Arena and Di Gregorio [9] carried out air gasification of solid-recovered fuel in a 400-kW pilot-scale fluidized-bed gasifier, producing a syngas suitable for direct combustion. Dunnu et al [10] studied Stabilat solid-recovered fuel gasification with air in two fluidized beds under various operating conditions and determined the optimum operating parameters. Nevertheless, air gasification only yields low-heating value gas (4-5 MJ Nm ) but requires high cost for pure oxygen.…”

Enriched‐Air Gasification of Refuse‐Derived Fuel in a Fluidized Bed: Effect of Gasifying Conditions and Bed Materials

et al. 2014

Enriched-air gasification of refuse-derived fuel (RDF) was carried out in a fluidized bed, investigating the effects of temperature, equivalence ratio (ER), oxygen percentage of enriched air (OP), and bed materials. For the bed material effect, calcined dolomite proved to be more effective for tar decomposition and resulted in higher CO and H 2 contents. In a bed of high-alumina bauxite, an increased ER tended to cause a greater decrease in syngas quality. For both bed materials, a higher temperature and OP favored the production of combustible gas and led to higher cold gas efficiency. Increasing the ER resulted in higher gas yields and carbon conversion but lowered the concentration of the combustible component. The ash content of the char increased with temperature and OP, while the volatile and fixed carbon contents were decreased. The optimum conditions suggested in this study were an ER of 0.22 and an OP of 44.7 % at 750-800°C in a bed of calcined dolomite.

“…In addition, it is a propitious route to produce fruitful end products using various synthesis routes [10]. In the past decades, gasification of biomass and waste has been comprehensively studied by many researchers [11][12][13], whereas, in the present day, gasification of solid recovered fuel (SRF), an alternative fuel produced from the combustibles in MSW, is one of the key topics in waste gasification [1,[14][15][16].In South Korea, during the SRF manufacturing process, there is a significant amount of residue generated which approaches 40 wt% of input waste, and the disposal cost occupies 20% of the annual operating cost in a few manufacturing facilities [17]. The SRF residue produced as leftovers during the SRF manufacturing process is usually discarded in landfill because of its high ash content (>20 wt%) and high moisture content (>10 wt%) but low energy content (<3500 kcal/kg).…”

Co-Gasification of Treated Solid Recovered Fuel Residue by Using Minerals Bed and Biomass Waste Blends

et al. 2020

Solid recovered fuel (SRF) residue, which is leftovers from the SRF manufacturing process, usually is discarded in landfill because of its low heating value and high ash and moisture content. However, it could be used as a fuel after mechanical and biological treatment. Gasification experiments were conducted on treated SRF residue (TSRFR) to assess the viability of syngas production. Efforts were also made to improve the gasification performance by adding low-cost natural minerals such as dolomite and lime as bed material, and by blending with biomass waste. In the case of additive mineral tests, dolomite showed better performance compared to lime, and in the case of biomass blends, a 25 wt% pine sawdust blend with TSRFR showed the best performance. Finally, as an appropriate condition, a combined experiment was conducted at an equivalence ratio (ER) of 0.2 using a 25 wt% pine sawdust blend with TSRFR as a feedstock and dolomite as the bed material. The highest dry gas yield (1.81 Nm 3 /kg), with the highest amount of syngas (56.72 vol%) and highest lower heating value (9.55 MJ/Nm 3 ) was obtained in this condition. Furthermore, the highest cold gas efficiency (48.64%) and carbon conversion rate (98.87%), and the lowest residue yield (11.56%), tar (0.95 g/Nm 3 ), and gas pollutants content was observed.Energies 2020, 13, 2081 2 of 16 48,934 tons of MSW per day [8]. Usually, this MSW carries an incredible amount of materials like plastic, paper, wood, metals, and glass which can be recycled easily and effectively by doing energy recovery [9].Gasification of MSW is a productive way of generating heat and power. In addition, it is a propitious route to produce fruitful end products using various synthesis routes [10]. In the past decades, gasification of biomass and waste has been comprehensively studied by many researchers [11][12][13], whereas, in the present day, gasification of solid recovered fuel (SRF), an alternative fuel produced from the combustibles in MSW, is one of the key topics in waste gasification [1,[14][15][16].In South Korea, during the SRF manufacturing process, there is a significant amount of residue generated which approaches 40 wt% of input waste, and the disposal cost occupies 20% of the annual operating cost in a few manufacturing facilities [17]. The SRF residue produced as leftovers during the SRF manufacturing process is usually discarded in landfill because of its high ash content (>20 wt%) and high moisture content (>10 wt%) but low energy content (<3500 kcal/kg). However, the South Korean government has set a goal to reach 3% landfill for overall waste and zero landfill for recyclable waste by the year 2020 [8]. In addition, by the year 2050, the South Korean government aimed to expand the share of renewable and new energy to 20% [18]. Thus, to support the South Korean government's vision, in this study, an effort was made to recover energy from SRF residue via the gasification process. However, before applying the gasification process, to improve the quality of SRF residue it was tr...
