The history of fluidized bed technology dates back 60 years. Gasification of pulverized coal in the Winkler process during the 1920's marked the beginning of fluidized bed application. Consider­ ,able work done during World War II by U.S. oil companies to improve the catalytic cracking of kerosene led to the development of the Fluid Catalytic Cracking process. Fluidized bed technology later exp...

Resource recovery plants with a waste presorting process prior to incineration have not been successfully implemented in many developing countries. At least two engineering projects were fully assessed in Taiwan for the possible installation of presorting facilities in order to increase the potential efficiency of material and energy recovery for municipal incinerators. But the reuse potential ...

Biodrying is an essential part of the mechanical–biological treatment process that minimizes moisture content and simultaneously maximizes heating value for refuse-derived fuel (RDF) production. Although mechanical separation operates effectively in Thailand’s RDF production, high organic levels their degradation cause contamination RDF, producing wet RDF. Aeration effective biodrying process, ...

The chlorine content of municipal solid waste (MSW) and refuse derived fuel (RDF) plays a dominant role in combustion processes. In order to prevent operational problems, such as high temperature corrosion, quality assured analytical methods for the determination of the chlorine concentration are necessary. This paper presents results of the chlorine content of the main components of untreated ...

An explosion has recently occurred at a silo containing refuse-derived fuels (RDF) in Japan. There is a possibility that microorganisms are involved in generation of combustible gas from RDF and this study was aimed at showing the presence of bacteria that can ferment RDF pellets. All RDF samples tested contained a relatively high number of viable bacterial cells, 1.4x10(5) to 3.2x10(6) viable ...

This study was conducted to investigate health effects in workers at two refuse-derived fuel processing plants. Cross-shift pulmonary function testing and self reporting of symptoms from questionnaires formed the basis of a cross-sectional epidemiological study. Other topics addressed were exploration of the possibility of a hand to mouth component resulting in diarrhoea observed historically b...

Reuse and recycling are preferred strategies in waste management to ensure the high position of resources hierarchy. However, challenges still pronounced many developing countries, where disposal as a final solution is prevalent, particularly for municipal solid waste. On other hand, refuse-derived fuel means energy recovery provides sustainable option managing mixed, contaminated residual (MSW...
