Gasification and Co-gasification of paper-rich, high-ash refuse-derived fuel in downdraft gasifier

A. Fazil et al.

Summary: Gasification is a technically feasible method for municipal solid waste valorization, which can meet emission limits and reduce landfill burden. This study investigates the potential of using paper-rich commercial refused-derived fuel (RDF) with high ash content for gasification and co-gasification. The results suggest that co-gasification can reduce overall ash content and increase the heating value of the gas produced.

Multizone model of a refused derived fuel gasification: A thermodynamic Semi-empirical approach

Prateek Sharma et al.

Summary: The gasification of refuse derived fuel (RDF) is gaining importance as an alternative energy source. In this study, a multizone RDF gasification model is developed to predict syngas composition. The model takes into account the realistic assumptions and the heterogeneous nature of RDF, accurately predicting the output of each zone.

Numerical investigation of the impact of coating layers on RDF combustion and clinker properties in rotary cement kilns

C. Pieper et al.

Summary: This study investigates the impact of coatings on the cement clinker production process within a rotary kiln through CFD simulations. Results show that a thin coating profile can increase gas phase temperatures and reduce free lime content of the final product, while a heavy coating may lower local gas phase temperatures and result in a slight increase in free lime content in the clinker.

Alternative fuels co-fired with natural gas in the pre-calciner of a cement plant: Energy and material flows

Daya R. Nhuchhen et al.

Summary: The study highlights the impact of cement-making on the environment and the potential for reducing this impact through the use of alternative fuels, but also emphasizes the importance of considering fuel properties and combustion requirements. The use of certain alternative fuels may result in an increase in overall carbon dioxide emissions.
