The respiratory toxicity of coal fly ash
The aim of this study was to compare the relative respiratory toxicity of CFA samples obtained from three Chinese coal-burning power stations to CFA obtained from a UK coal-burning power station; both bulk and respirable PM10 samples were tested. In order to elucidate CFA toxicity, a multi-disciplinary approach was taken, thereby considering geochemical aspects of the fly ash as well as biochem...
متن کاملCoal Fly Ash Ceramics: Preparation, Characterization, and Use in the Hydrolysis of Sucrose
Coal ash is a byproduct of mineral coal combustion in thermal power plants. This residue is responsible for many environmental problems because it pollutes soil, water, and air. Thus, it is important to find ways to reuse it. In this study, coal fly ash, obtained from the Presidente Médici Thermal Power Plant, was utilized in the preparation of ceramic supports for the immobilization of the enz...
متن کاملHealth aspects of coal fly ash
Employees of coal-fired power stations and people living nearby as well as those involved in the shipment and processing of coal fly ash can be exposed to coal fly ash (pulverised fuel ash or “PFA”). An extensive research program was carried out in order to map such exposure and its effects. Particle size distribution, chemical composition, quartz, radioactivity, emission factors and fugitive d...
متن کاملProduction geopolymer materials by coal fly ash
Coal ash is the main waste from power plant. It is estimated that the consumption of the coal for power plant will increase to 240 million tons each year and the coal ash wastes will produce more than 2 million tons per year. Although the utilization of coal fly ash can be reached 74.1%, large amount of coal fly ash and bottom ash still cannot be utilized. The purpose of this research is to dev...
متن کاملRecycling of Coal Fly Ash for the Fabrication of Porous Mullite/Alumina Composites
Coal fly ash with the addition of Al₂O₃ was recycled to produce mullite/alumina composites and the camphene-based freeze casting technique was processed to develop a controlled porous structure with improved mechanical strength. Many rod-shaped mullite crystals, formed by the mullitization of coal fly ash in the presence of enough silicate, melt. After sintering at 1300-1500 °C with the initial...
