Analyse der RDF-Produktion in Vietnam / Analyze of RDF-production in Vietnam

Schulenburg, Sven 02 August 2010 (has links)
A simplified RDF production was made, together with a waste characterization of MSW from Hanoi area. Three experiments were done, two with active aeration and one without. A high water content was determined at all RDF, which has a negative influence on the lower heating value and a saving-effect. A accumulation of the heating value to the higher class (>40mm), was not completely possible, also no complete transfer of mineral contents to the lower class (<10mm). The RDF reach in most cases the criteria for a fuel for different limit values, heavy metals, chloride and sulfur. An economic benefit could be possible with a surplus income by using RDF instead of coal (lignite), also by avoiding landfill gas and sell emission rights via CDM. More and detailed investigations seem to be necessary to confirm these results.:I. Index I II. Abbreviations III III. List of Tables IV IV. Figures VII V. Acknowledgements VIII VI. Summary IX 1.
