Preparation and characterization of carbon-enriched coal fly ash.
Carbon-enriched fractions have been obtained from two coal fly ash (FA) samples. The FA came from two pulverized-coal fired power stations (Lada and Escucha, Spain) and were collected from baghouse filters. Sieving was used to obtain carbon-enriched fractions, which were further subjected to two beneficiation processes: acid demineralization using HCl and HF, and oil agglomeration using soya oi...
متن کاملEvaluation of Coal Waste Ash and Rice Husk Ash on Properties of Pervious Concrete Pavement
The use of pervious concrete has been significantly considered in recent years. This consideration is due to the properties of pervious concrete in relating to the environmental sustainability that is utilized in the effective management of the runoff from rainfall. Coal extraction and rice husk obtained from milling, produces wastes that have no application and followed by environmental pollut...
متن کاملDistribution of trace elements in coal and coal fly ash and their recovery with mineral processing practices: A review
Today coal is among the most important energy sources. In order to meet the world's energy demands, low-calorie lignite with a high ash content is generally used in the large capacity coal-fired thermal power plants. As a result of coal firing, wastes such as fly ash, slag, and flue gas are also produced. Subsequently, toxic trace elements within coal are transferred to wastes such as slag, fl...
متن کاملThe 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 کاملResearch on the Whiteness and Properties of Modified Coal Fly Ash
In the filling of polymer, coal fly ash has been limited in use by its unlovely grey color. In order to improve the qualities of coal fly ash from Huaneng Power international Incorporation Dezhou Power Plant, its meso-structure and influencing factors on whiteness have been tested and analyzed. Ca(OH)2-H2O-CO2 system to modify the fly ash is conducted. Round coating testify that the system can ...
