Developing an all-round combustion kinetics model for nonspherical waste-derived solid fuels

Abstract

The utilization of challenging solid fuels in the energy industry (especially the ones derived from wastes) has a big priority nowadays, as it is a valid option to keep the recent EU directive related to the decrease of landfills. However, there are serious technical challenges, connecting to the lack of knowledge about the behavior of these fuels in the combustion chamber. This paper discusses the specific aspects of developing particle models concerning the combustion of these non-conventional fuels. A new modeling approach is presented, using which it is possible to develop an all-round particle model that includes every significant influencing process. Moreover, it does not have any restrictions regarding the shape, size and the origin of the particle. As an integral component of this model, the distinctive aspects of intrinsic reaction kinetics related to waste fuels are presented as well.

Carbon Footprint Evaluation of Hazardous Waste Based Solid Fuel: Application in a Cement Kiln

“…Solid waste treatment methods play some degree of impact on global warming (Arshadi & Yaghmaei, 2020). Solid fuel is derived from recyclable municipal solid wastes or industrial solid wastes (Kara, 2012;Szűcs & Szentannai, 2021) with an average heating value of 3,000 kcal/kg 6,000 kcal/kg (Chen et al, 2012). The study conducted by Chen and others (2011) shows that when Refused Drive Fuel (RDF) is used as feedstock for producing electricity in Refuse Recycling Centre/Waste to Energy (RRC/WtE) facility, the carbon footprint of electricity is reduced to 0.14 kg/kWh as compared to the national electric power in Malaysia at 0.60 kg/kWh (Chen, Ismail, Adnan, & Ramasamy, 2011).…”
