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...
متن کاملRecovery of Calcium Sulfate Hydrates from SDA Waste Sludge and Bag Filter Ashes
Abstract— SDAWS (Spray drying absorption waste sludge) and BFA (bag filter ash), which are the wastes generated in the SDA (pray drying absorption) process, are only partially recycled as cement additives, gypsum boards, building materials, and the rest are being landfilled in managed landfills. However, wastes that have not been disposed of at the landfill are accumulated around the landfill. ...
متن کاملHigh efficiency power production from biomass and waste
Two-stage gasification allows power production from biomass and waste with high efficiency. The process involves pyrolysis at about 550°C followed by heating of the pyrolysis gas to about 1300°C in order to crack hydrocarbons and obtain syngas, a mixture of H2, CO, H2O and CO2. The second stage produces soot as unwanted by-product. Experimental results are reported on the suppression of soot fo...
متن کاملPhosphorus recovery from municipal solid waste incineration fly ash.
The potential of phosphorus (P) recycling from municipal solid waste incineration (MSWI) residue is investigated. Vast and ever increasing amounts of incineration residues are produced worldwide; these are an environmental burden, but also a resource, as they are a major sink for the material flows of society. Due to strict environmental regulations, in combination with decreasing landfilling s...
متن کاملResource Recovery from Hazardous Waste – the Case of Msw Incineration Fly Ashes
(2014) " Resource recovery from hazardous waste – the case of MSW incineration fly ashes " In: Proceedings " 4th International Conference Industrial and Hazardous Waste Management", 2.-5. SUMMARY: In the European Union almost 78 million tons of waste are annually combusted in Waste-to-Energy plants. Solid residues generated thereby contain altogether about 72,000 t/a of Zn, of which more than 5...
