Prototype Fly Ash Monitor for Municipal Incinerator Stacks
In anticipation of stricter legislative control of emissions, a project was undertaken to define some of the design parameters required for an automatic fly-ash monitor suitable for application to municipal incinerator stacks. An instrument was designed to separate fly ash from a measured mass of sampled gas by a cyclone and filter combination and to mea sure its mass by a beta gauge technique...
متن کاملToxicity mitigation and solidification of municipal solid waste incinerator fly ash using alkaline activated coal ash.
Municipal solid waste (MSW) incineration is a common and effective practice to reduce the volume of solid waste in urban areas. However, the byproduct of this process is a fly ash (IFA), which contains large quantities of toxic contaminants. The purpose of this research study was to analyze the chemical, physical and mechanical behaviors resulting from the gradual introduction of IFA to an alka...
متن کاملProduction of glass-ceramic from incinerator fly ash
Vitrification is one of the technological options for treating toxic waste. This paper reports the results of the feasibility study of utilizing fly ash from municipal waste incinerators by powder sintering technology. This process was used to transform vitrified incinerated fly ash into a CaO–Al2O3–SiO2 system of glass ceramic products. The major phase exhibited is gehlenite (Ca2Al2SiO7), whic...
متن کاملChloride extraction for quality improvement of municipal solid waste incinerator ash for the concrete industry.
Coal ash from power stations has long been used successfully in the cement industry as binders in several Portland formulations. This is not the case for municipal solid waste (MSW) ash as chloride concentrations, ranging from 10 to 200 g kg(-1) dry weight in the bottom and fly ash, respectively, exceed the maximum allowable concentration in most cement mixtures. To reduce chloride content in M...
متن کاملProperties of Concrete with Municipal Solid Waste Incinerator Bottom Ash
The appropriate utilization of Municipal Solid Waste Incineration (MSWI) residues is a worldwide studied topic over the last decades. One of the possibilities is to use MSWI ashes in concrete production, as it is done with coal combustion products. The bottom ash features the most convenient composition for this purpose, and it is available in highest amounts among the MSWI ashes. Untreated bot...
