Effect of CaO, Al2O3 and Fe2O3 in coal ash on the retention of acid- forming elements during coal combustion
نویسنده
چکیده
Industrial coal combustion ashes as well as laboratory-scale experiments were used for the evaluation whether CaO, Al2O3 and Fe2O3 can help with the retention of volatile and acid-forming elements (S, Cl, Br, As and Se). Both industrial ashes evaluation and laboratory combustion experiments lead to the conclusion that CaO can efficiently help with the capture of not only S, but also of Cl, Br, As and Se. Key-Words: Coal combustion, desulphurization, limestone, trace elements, emissions, sulphur, chlorine, bromine, arsenic, selenium

Distribution 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 کاملReduction of Sulfur and Ash from Tabas Coal by Froth Flotation
Tabas mines in Iran have coal sources which are suitable for use in metallurgy industries as coking coal. But the high sulfur content of this coal imposes severe limitations on its utilization as the sulfur oxide gases evolved from the combustion of high sulfur coals result in acid rains and corrosion of equipments. In this work, attempts have been made to reduce sulfur from high sulfur coa...

The Galand-rud coal mine is one of the coal producing areas of central Alborz coal basin which is located in Mazandran Province. Based on mineralogical and geochemical studies pyrite is the main sulfide mineral in the mine. Based on correlation matrix, cluster analysis and principle component analysis (PCA), SiO2, Al2O3, Na2O, K2O and TiO2 are associated with alluminosilicate minerals, CaO, MgO...
متن کاملArsenic and selenium capture by fly ashes at low temperature.
Arsenic and selenium compounds may be emitted to the environment during coal conversion processes, although some compounds are retained in the fly ashes, in different proportions depending on the characteristics of the ashes and process conditions. The possibility of optimizing the conditions to achieve better trace element retention appears to be an attractive, economical option for reducing t...
