On the Radioactivity of Fly Ashes from Coal Power Plants

The radioactivity of Greek lignites and their ashes was studied. It was found that the radionuclides in them belong to the uranium series. Fly ashes are relatively rich in radioactivity. Concentrations up to 7 , 1 0 _ 5 g / g and 12 pCi/g were measured for 238U and 226Ra, respectively. The associated hazards from radioactivity escaping from stacks of thermopower plants or when fly ashes are use...

Arsenic leachability and speciation in fly ashes from coal fired power plants

To determine dominant factors on arsenic leaching from the coal fly ash, arsenic leaching test under a constant pH was performed. Twelve fly ash samples were collected from two coal fired power plants (600 MWe) having different boiler types. Arsenic in the raw coal was almost all associated with the fly ash in both power plants; however arsenic leaching fraction was strongly differed in boiler ...

Treatment of fly ash from power plants using thermal plasma

Fly ash from power plants is very toxic because it contains heavy metals. In this study fly ash was treated with a thermal plasma. Before their treatment, the fly ash was analyzed by many technics such as X-ray fluorescence, CHN elemental analysis, inductively coupled plasma atomic emission spectroscopy and scanning electron microscopy. With these technics, the composition, the chemical and phy...

Physical Characteristics Of Fly Ashes From Three Thermal Power Plants In West Bengal, India: A Comparative Study

A comparative analysis on the physical nature of the fly ashes, obtained from three thermal power plants, situated in West Bengal, India is presented in this work. The particle size of the fly ash samples are estimated, and their morphology and compositional analysis are made. These samples are crystalline, and the major components are mullite and quartz. Quantitative magnetic characterizations...

Activated carbons from oil-fired fly ashes

Introduction. The aim of this investigation is to prepare activated carbons with good sorbent characteristics from oil-fired fly ash, looking for suitable activation processes to produce surface sites with high reactivity on the carbonaceous matrices [1-4]. In particular, the nitrogen surface sites, formed by gaseous ammonia reaction at 800°C, could greatly increase the adsorption of gaseous sp...
