Toxicity 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 کاملPrototype 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 کاملCarbonation of Brine Slurried Size Fractionated Coal Combustion Fly Ash
Coal combustion by-products such as fly ash (FA), brine and CO2 from coal fired power plants have the potential to impact negatively on the environment. Reaction of CO2 with FA/ brine slurry can potentially provide a viable route for CO2 sequestration through formation of mineral carbonates. Fractionated FA has varying amounts of CaO which not only increases the brine pH but can also be convert...
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 کاملAdsorption of tungsten onto zeolite fly ash produced by hydrothermally treating fly ash in alkaline solution.
Fly ash (FA) was hydrothermally treated in an alkaline solution to produce zeolite fly ash (Z-FA). The properties of the FA and Z-FA were investigated. The amounts of tungsten (W) adsorbed onto the FA and Z-FA surfaces were evaluated. Z-FA was produced by hydrothermally treating FA in an alkaline solution. The specific surface area and pore volume of the Z-FA were greater than those of the FA. ...
