Effect of alkaline activator composition on the geopolymer properties produced from South African power station fly ash
(North-West University (South Africa)., 2022)Eskom produce ~36 million tons of ash annually, of which 90 % is fly ash. Only 7 % of the ash is valorised; much lower than the global average of ~75 %. Geopolymer production from fly ash, as a Portland cement substitute, ... -
Evaluation and modelling of particle collection efficiency of electrostatic precipitation
(North-West University (South Africa)., 2023)Many South-African power plants use wire-plate electrostatic precipitators (ESPs); however, these ESPs, in practice, have yet to meet the expected high particle collection efficiencies and present relatively low collection ... -
The occurrence of hazardous volatile elements and nanoparticles in Bulgarian coal fly ashes and the effect on human health exposure
(Elsevier, 2012)Low-rank, high-mineral matter Bulgarian coals were studied using a variety of chemical, optical, and electron beam methods. The larger fly ash carbon phases include charred carbons in contrast to coked carbons present in ...
