“…Although the emission control systems have high efficiency rates (near 99.9%), considerable amounts of FA can be emitted into the surrounding environments because of high coal consumption rates of TPPs, the emissions being even greater if the ash content of coal is high (Turhan et al, 2010;Mehra et al, 1998). Also, accumulation of FA stored in piles can contribute to environmental radiological problems through its dispersal into atmosphere and its handling or disposal (Chauhan et al, 2003).…”

“…Economic and environmental problems have led to the implementation of various alternative utilisations, in which FA is considered as value-added product. There are difficulties around the world to achieve effective utilisation (Turhan et al, 2010;Ozbayoğlu and Arslan, 2013). Roughly 1% of the total FA produced in Turkey is being used in a variety of products such as cement, concrete, aggregate in stabilising roadways, etc.…”

Electricity generation in coal fired power plants produces large amount of residues. These materials are known as coal combustion products (CCPs) and can release pollutants to the environment. However, CCPs are environmentally and technically suitable for uses in many areas. The utilisation of CCPs in these areas helps to reduce the overall harmful effects of coal combustion for electricity generation by stabilising the environmentally toxic pollutants. The current paper reveals the possible usage areas of improved ash and presents the general approaches have been developed to obtain improved fly ash. Electrostatic separator with tribocharging technique has great potential for utilisation of coal ash. It significantly contributes to reduce fly ash disposal problems. In recent years, triboelectrostatic separators have increased significantly for the feasibility and success of the implementation of electrostatic separation. Studies carried out by various researchers on triboelectrostatic separation for utilisation of fly ash were also compiled in this article.

“…Przy stosowaniu FA do betonów wskaźnik radioaktywności tego materiału jest wyższy w porównaniu do wskaźnika betonu bez dodatków, ale nadal znajduje się w granicach bezpiecznych dla człowieka (Golewski, 2015). Z uwagi na to, że problem promieniotwórczości naturalnej betonów z dodatkiem FA został już rozpoznany (Turhan, Arıkan, Yücel, Varinlioǧlu i Köse, 2010;Kovler, 2012;Golewski, 2015), w poniższej pracy przedstawiono wyniki badań radioaktywności betonów wykonanych na spoiwach trójskładnikowych, tzn. z łącznym dodatkiem FA i SF.…”

Abstract. Use of the coal in order to generate electricity increases the exposure of people to radiation. In this paper, the activity concentrations of nuclides 226 Ra, 232 Th and 40 K in samples of coal and bottom ash from the Yatagan Coal-Fired thermal power plant determined using gamma ray spectrometer with a NaI(Tl) scintillation detector. The mean activity concentrations of 226 Ra, 232 Th, and 40 K in the coal were found to be 37.2±2.8 Bqkg -1 , 51.8±3.4 Bqkg -1 and 166.7±11.1 Bqkg -1 , respectively. Whereas in the bottom ashes, the concentrations of the corresponding radionuclides were found to be 62.2±5.6 Bqkg -1 , 87.4±5.9 Bqkg -1 and 221.0 ±12.5 Bqkg -1 , respectively. The findings show that bottom ashes show higher activity concentrations of related radionuclide to coal samples. The absorbed gamma dose rate in outdoor air DR OUT and annual effective dose rate (AED) from coal were calculated to define radõologõcal rõsk. The average findings of annual effective doses were detected as 68.6±5.1 µSvy -1 and 110.3±11.2 µSvy -1 , respectively.
