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 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 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 کاملIncinerator Ash - Criteria of Performance
The object of this paper is to throw light on the criteria which apply to the degree of burn-out on a furnace burning mixed household and trade refuse. In particular, the paper concentrates on the ash discharged from the end of the grate since this represents the bulk of the ash produced by the plant. The classical approach to burn-out is to employ "carbon-in-ash" techniques familiar to combust...
متن کاملSize characterization of incinerator fly ash using sedimentation/steric field-flow fractionation.
Fly ash particles emitted from municipal solid waste-incinerators are of environmental concern. This study aims to investigate the applicability of sedimentation/steric field-flow fractionation (Sd/StFFF) and to develop a Sd/StFFF method for the separation and size characterization of incinerator fly ash. This study focuses on the fly ash particles larger than approxiamtely 1 microm, which comp...
