Particle size distribution and qualitative/quantitative analysis of trace metals in the combustion gas and fly ash of coal/refuse derived fuel (open access)

Particle size distribution and qualitative/quantitative analysis of trace metals in the combustion gas and fly ash of coal/refuse derived fuel

This work includes two different areas of research. Both areas are related to the combustion of the binder-enhanced densified refuse derived fuel (bdRDF) with high sulfur coal and examining trace elements. The first area of this work involved studying the trace metals in the combustion gas of bdRDF/coal blend and the effect of the binder, CA(OH)2, on reducing the trace elements emissions. The second area of work involved studying the trace elements in the fly ash and the effect of the dRDF and the binder of trace metals.
