WebThe fly ash used to synthesize zeolite was obtained from a Polish heat power plant (hard-coal combustion, pulverized bed). The chemical composition of the fly ash and zeolite was investigated with X-ray fluorescence (XRF) using an Epsilon 3 PANalytical XRF spectrometer and is presented in Table 1 . Table 1. WebAbstract Circulating fluidized bed combustion (CFBC) is known for its ability to significantly reduce the emission of NO x and SO 2 from coal combustion. However, the fly ash produced from CFBC (CFBFA) is impractical for use as a construction material due to its low pozzolanic activity.
