Integrated municipal solid waste treatment using a grate furnace incinerator: the Indaver case

An integrated installation for treatment of municipal solid waste and comparable waste from industrial origin is described. It consists of three grate furnace lines with flue gas treatment by half-wet scrubbing followed by wet scrubbing, and an installation for wet treatment of bottom ash. It is demonstrated that this integrated installation combines high recovery of energy (40.8% net) with high materials recovery. The following fractions were obtained after wet treatment of the bottom ash: ferrous metals, non-ferrous metals, three granulate fractions with different particle sizes, and sludge. The ferrous and non-ferrous metal fractions can both be recycled as high quality raw materials; the two larger particle size particle fractions can be applied as secondary raw materials in building applications; the sand fraction can be used for applications on a landfill; and the sludge is landfilled. For all components of interest, emissions to air are below the limit values. The integrated grate furnace installation is characterised by zero wastewater discharge and high occupational safety. Moreover, with the considered installation, major pollutants, such as PCDD/PCDF, Hg and iodine-136 are to a large extent removed from the environment and concentrated in a small residual waste stream (flue gas cleaning residue), which can be landfilled after stabilisation.

Leaching tests to evaluate pollution potential of combustion residues from an iron recycling industry

Three leaching tests were applied to an industrial fly ash (cupola dust) for the evaluation of its groundwater pollution potential. The tests comprised two batch shaking tests (the SLT-test and a titration test) and a column leaching test (laboratory scale). All three tests gave valuable and consistent results with respect to the leaching of lead, zinc, cadmium and organic matter. The pH of the leaching environment was the most important factor in governing the leaching process. The results of the leaching seemed to be in accordance with observations of the groundwater quality below an actual industrial fly ash disposal site. The combination of the SLT-test and the titration test appears to be a cost-effective means of evaluating the groundwater pollution potential from industrial fly ashes.

Treatment Of Electric Arc Furnace Dust With A Sustained Shockwave Plasma Reactor

In the reprocessing of steel from automotive scrap, lead, cadmium and zinc, which are volatile constituents, vaporize under the extremely high localized temperatures in an electric arc furnace at the points of contact between the graphite electrodes and the charge. These vapors condense to produce a hazardous dust termed electric arc furnace dust (EFD). This study was undertaken to satisfy the need for a mobile system which could be moved from site to site of generators of EFD to avoid transportation of hazardous waste, and to recycle slags and metallic iron products within the plant. A new type of plasma device, the Sustained Shockwave Plasma (SSP) has been developed and tested for treatment of EFD on a laboratory scale (500 g h^-1). Batch tests show that EFD can be treated to produce a non-hazardous slag and metallic zinc and lead to recycle.

Simulation of co-incineration of sewage sludge with municipal solid waste in a grate furnace incinerator

Incineration is one of the most important methods in the resource recovery disposal of sewage sludge. The combustion characteristics of sewage sludge and an increasing number of municipal solid waste (MSW) incineration plants provide the possibility of co-incineration of sludge with MSW. Computational fluid dynamics (CFD) analysis was used to verify the feasibility of co-incineration of sludge with MSW, and predict the effect of co-incineration. In this study, wet sludge and semi-dried sludge were separately blended with MSW as mixed fuels, which were at a co-incineration ratios of 5 wt.% (wet basis, the same below), 10 wt.%, 15 wt.%, 20 wt.% and 25 wt.%. The result indicates that co-incineration of 10 wt.% wet sludge with MSW can ensure the furnace temperature, the residence time and other vital items in allowable level, while 20 wt.% of semi-dried sludge can reach the same standards. With lower moisture content and higher low heating value (LHV), semi-dried sludge can be more appropriate in co-incineration with MSW in a grate furnace incinerator.
