Modelling of Solid Recovered Fuel (SRF) Properties Based on Material Composition – Chloride Quality
© TK Verlag - Fachverlag für Kreislaufwirtschaft (9/2016)
Producing solid recovered fuels (SRF) is a well-established route for recovering energy resources from municipal solid waste (household and/or commercial). Chloride content critically impacts the quality of SRF. It directly influences operation of thermal processes, having deleterious effects through the high temperature corrosion of the boilers and through demands placed on the flue gas treatment (FGT) system, which could impact emissions control. Whereas design and specification of process plant can mitigate the technical issues associated with the presence of chloride experienced during thermal treatment, processing such fuels is associated with increased capital, operating and maintenance costs. This, at best, restricts the uptake/use of SRF or increases the cost of its treatment towards achieving a reduced chloride content.
Mapping air pollution: the city of Thessaloniki - Greece case study
© Aristotle University of Thessaloniki (6/2009)
Air pollution is a global problem that affects natural ecosystems and poses a significant human health risk. The main objective of this study is the evaluation and mapping of air pollution levels. This paper examines traditional and new techniques and processes of mapping a geographic phenomenon like air pollution, which requires spatial methods and algorithms.
