Comparison of coal/solid recovered fuel (SRF) with coal/refuse derived fuel (RDF) in a fluidized bed reactor.

An experimental study was undertaken to compare the differences between municipal solid waste (MSW) derived solid recovered fuel (SRF) (complying with CEN standards) and refuse derived fuel (RDF). Both fuels were co-combusted with coal in a 50 kW fluidized bed combustor and the metal emissions were compared. Synthetic SRF was prepared in the laboratory by grinding major constituents of MSW such...

Effect of Sludge Amendment on Remediation of Metal Contaminated Soils

Column-leaching and pilot-scale experiments were conducted to evaluate the use of biosolids (sewage sludges) to control the mobilization of metals from contaminated soils with smelting slags. The pilot-scale experiments using amended soils showed that Cu, Pb and Sb were retained, decreasing their concentrations from 250 g/L, 80 g/L and 6 g/L, respectively in the leachates of contaminated soi...

a study of underground coal gasification (ucg) wastewater and sludge

underground coal gasification (ucg) is a non-conventional method of extracting gas from coal. the primary advantage of ucg is that it recovers gas from uneconomical or unminable coal, potentially increasing the value of the world’s coal reserves by an estimated 70%; for this reason, ucg has been implemented at sites around the world. however, the gaseous, liquid and solid waste streams which ac...
