Emissions during co-firing of RDF-5 with bituminous coal, paper sludge and waste tires in a commercial circulating fluidized bed co-generation boiler

Pyrolysis characteristics of coal and RDF blends in non-isothermal and isothermal conditions

“…The limestone (CaCO 3 ) is added to manufacturing process of RDF to deodorize and remove HCl emission for RDF combustion. The addition of limestone could facilitate capture of sulfur and chlorine in gaseous phase [27]. This is also confirmed from XRD pattern of RDF/blend = 0.5 char as can be seen in Fig.…”

Refuse-derived fuel classification in a mechanical–biological treatment plant and its valorization with techno-economic criteria

“…This indicates that the produced RDF has significantly higher moisture content than other RDF samples studied. (Liu et al 2001;Wan et al 2008;Montejo et al 2011) More specifically, from the pre-drying procedure followed for all of the increments of each sample, moisture was found to be more than 32 % in the majority of the samples. The maximum moisture found in a daily increment was 47.57 %, and the minimum was 31.60 %.…”

Valorization of co-combustion fly ash in concrete production

“…RDF is obtained from the separation of the high calorific fraction from municipal solid waste, through a mechanical-biological treatment, and it mainly consists in paper and plastics, with minor content of wood and textile. This material has a relatively high lower heating value (LHV) with respect to other supplementary fuels, which makes it particularly suitable for the intended application: it is characterized by an average LHV of 17 MJ/kg, greater than residual waste (10.617 MJ/kg) and paper sludge (2.537 MJ/kg) [3,7]. According to the production data of 2013, this plant produces about 49,000 t/y of coal-fly ash (CFA), and about 155,000 t/y of co-combustion fly ash (CCFA).…”
