- W2238759929 abstract "�Abstract—Work is focused to the study of unburned carbon in ash from coal (and wastes) combustion in 8 combustion tests at 3 fluidised-bed power station, at co-combustion of coal and wastes (also at fluidized bed) and at bench-scale unit simulating coal combustion in small domestic furnaces. The attention is paid to unburned carbon contents in bottom ashes and fly ashes at these 8 combustion tests and to morphology of unburned carbons. Specific surface area of coals, unburned carbons and ashes and the relation of specific surface area of unburned carbon and the content of volatile combustibles in coal were studied as well. Keywords—Coal combustion, emissions, toxic elements, unburned carbon. I. INTRODUCTION CCORDING to International Energy Agency (2008) and World Coal Association, coal covers about 41% of electricity generation today in worldwide scale; in some countries the proportion is even significantly higher, e.g. in South Africa (93%), Poland (92%), PR China (79%), Australia (77%), India (69%), USA (49%), Germany (46%) etc. In the Czech Republic the share is about 60%. Moreover, the importance of coal in electricity generation in near future is thought to increase up to 44% worldwide (1).Even if modern coal combustion technologies are being tested and used, coal combustion is still accompanied by negative impact on the surrounding environment, from which the release of emissions containing toxic elements is one of the most significant. Since the efficiency of particulate control devices is generally high, the most problematic elements are those that remain in flue gas in gaseous form coming through the precipitator or fabric filter. For the retention of these volatile elements (such as Hg, Cl, Br, As, Se etc.) many adsorbents are being tested (2-4), from which the most common is the adsorption of Hg on activated carbon (5-7). Even if the adsorption efficiency of activated carbon is generally good, rather problematic is somewhat high cost of this material. This is the reason why some new precursors are being sought. Many waste materials are being tested because their possible utilization would bring another benefit.This work deals with unburned carbon - carbonaceous particles of unburned coal present to grater or lesser extent in all ashes. The particular attention was paid to the unburned carbon content in ashes collected at various coal combustion units as well as to unburned carbon adsorption characteristics in terms of the" @default.
