Fly ash contains the radiochemical polluting elements of the U and Th series, along with other radioactive contaminants like 222 Ru and 220 Ru. Bhangare et al. (2014) measured the radioactivity of 238 U, 226 Ra, 232 Th and 40 K for fly ash from six power plants across India. All the samples were found enriched with the radionuclides.
Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coalfired boilers together with the flue gases.

Ca levels of fly ash from cocombustion of wood with coal were lower than those of fly ash coming from the combustion of wood solely. When the proportion of wood in the coal/wood mixture is increased, the concentration of alkalis (Na and especially K) is also elevated.

Mar 15, 2019· It was further found that lowCa class F fly ash was the most suitable to obtain zeolite NaP1 crystals. Alternatively, highCa class C fly ash promoted the synthesis of hydroxysodalite and calcite. Higher porosity (52%) and surface area ( m 2 /g) were achieved for the geopolymersupported zeolites. These materials can be potentially used ...
