Evaluating the health impacts of incinerator emissions
free download
Before a municipal solid waste incinerator (MSWI) can be operated, it is generally required that a health risk assessment be performed and that human health risks predicted fall below permissible levels. There are several components to the risk assessment paradigm
Comparative evaluation of municipal solid waste incinerator designs by flow simulation
free download
Flow simulations have been carried out to evaluate the effects of combustion chamber design and air/combustion gas flow configuration on the overall performance of municipal solid waste incinerators. Computational results show velocity and temperature fields in the
Trace element pollution of soils collected near a municipal solid waste incinerator : human health risk
free download
MATERIALS AND METHODS Soil samples were collected in the vicinity of a MSW incinerator located in Montcada (Spain) at approximately 10 km from Barcelona. The plant is placed in a residential area with important industrial activity and began operating in 1975
Characterization of solid waste incinerator bottom ash and the potential for its use
free download
This paper evaluates the properties of incinerator bottom ash from Kano Municipal solid waste to see what uses the material could be put to after incineration. The properties of the material make it suitable for use as fills, low cost road subgrades and sub-bases. The
Plasma vitrification of waste incinerator ashes
free download
The results of vitrification of partially toxic ashes mixed with the power plant fly ash are presented and discussed The vitrification process was done with the use of plasma torch reactor. The vitrified product properties including hardness and leaching tests results for
Recovery of metals from waste incinerator bottom ash
free download
Metal extraction from the incineration residue of municipal waste is not only environmentally beneficial but also profitable. The literature on the topic is unfortunately rather fragmented. While many publications deal with the leaching behavior of Municipal Waste Incinerator
Effluent Water from Incinerator Flue Gas Scrubbers

design conditions followed by a series of six tests which consistently show results meeting design conditions and fortunately because this paper is a verification that refuse is a fuel that can be ap plied for steam generation. The results also indicate that refuse emits low
PCDD/F removal efficiencies of electrostatic precipitator and wet scrubbers in IZAYDAS hazardous waste incinerator
free download
SUMMARY PCDD/F removal efficiencies of the electrostatic precipitator and the wet scrubbers in IZAYDAS Incinerator were examined in a trial burn. Both units showed removal efficiencies higher than 90% for all congeners and homologues, producing> 99% removal of
Performance of the New Chicago Northwest Incinerator
free download
A paper presented by James A. Fife, during the 1970 National Incinerator Conference has described the de sign of the Northwest Incinerator for the City of Chicago . Operation of the incinerator plant was started during September 1 970 and in 1971 all four 400 tons/day
Radioactivity in size-separated municipal incinerator ashes
free download
Radionuclide concentrations of the U-and Th-decay series, as well as K and Cs, were determined in size-separated fly ashes and bottom ashes from two municipal incinerators. Secular equilibrium was observed for several of the series radionuclides, though Rn
Incinerator in Malaysia: really needs
free download
Increasing population, tremendous urbanisation growth and rapid economic growth influence directly the Municipal Solid Waste generation in Malaysia. Thus, incineration is one of the considered methods of waste treatment that is quickly attracting the municipal
Study of a MSW incinerator : overall operation and on-site measurements over the grate
free download
ABSTRACT A measurement program of a municipal solid waste incinerator was carried out. The aim was to character ize the grates distributed off-gas temperature and com position. Simultaneously, all operating conditions were recorded. Two complete passes over the bed
Metals in MSW-Where are They and Where Do They Go in an Incinerator
free download
The source and fate of metals entering and leaving a modern municipal waste combustor [MWC] were identi fied during The WASTE Programs Burnaby, BC field exercise in June 1991. The solid waste feed was sorted, screened and the trace metals analyzed and the
The nature of incinerator slags
free download
Slag samples taken from three incinerators operated by the City of New York were investigated. The slags selected were taken from the point 01 greatest build-up immediatel), above the air cooled silicon carbide wall. Investigation included: a) Fusion point and
Gas generation in incinerator ash
free download
In recent years, explosions have occurred in certain phases of ash management in Sweden. Investigations have revealed that hydrogen have been present in all cases. It is supposed that the hydrogen is generated by chemical reactions of aluminium and other
Disposal of incinerator ash by adding to concrete
free download
Incinerator ashes are generally by-products of industrial and municipal waste incineration process. Because of their cementitous or pozzolanic properties they can serve as partial cement replacement material. These ashes have an inherent negative value, as they require
Corrosion of high alloy steels and Fe-Cr-alloys beneath deposits from waste incinerator plants

Life cycle assessment of bottom ash management from a municipal solid waste incinerator (MSWI)
free download
Thermal treatment of Municipal Solid Waste (MSW) results in various types of solid wastes, distinguishing mainly bottom, boiler and fly ashes and slag. To minimise waste generation it necessary to carry out primary measures for controlling residue outputs that involve
