Technical Aspects of using MSW Incineration Residue as Construction Materials

Mathematical modelling of MSW incineration on a travelling bed.

The rising popularity of incineration of municipal solid waste (MSW) calls for detailed mathematical modelling and understanding of the incineration process. In this paper, governing equations for mass, momentum and heat transfer for both solid and gaseous phases in a moving bed in a solid-waste incineration furnace are described and relevant sub-models are presented. The burning rates of volat...

Rock Masses as Construction Materials

A rock mass is a material quite different from other structural materials used in civil engineering. It is heterogeneous and quite often discontinuous, but is one of the materials in the earth's crust, which is most used in man's construction. Ideally, a rock mass is composed of a system of rock blocks and fragments separated by discontinuities forming a material in which all elements behave in...

Plants as factories for technical materials.

Until the latter part of the 19th century, humans were largely dependent upon contemporaneous biological sources for the production of all organic materials. Plants and animals provided the only sources of fibers, coatings, lubricants, solvents, dyes, waxes, fillers, and insulation, fragrances, detergents, sizing, leather, wood, paper, rubber, and many other types of materials. As recently as 1...

Resource Efficient Management of Msw Incineration Fly Ash – the Case of Vienna

Effect of improving flue gas cleaning on characteristics and immobilisation of APC residues from MSW incineration.

The flue gas cleaning system of a MSW incinerator with a capacity of 350 kt/year was changed to improve the HCl elimination efficiency. Instead of the semi-wet operating spray reactor and subsequent baghouse, a two-step wet flue gas cleaning was added behind the baghouse. Elemental composition, X-ray powder diffraction patterns and TGA measurements showed that the resulting APC residue was tota...
