In an experimental study of cofiring, where the amount of biomass mixed with coal was in the range of 0%–16% on the basis of energy input, at a high feed rate of biomass of about 24 t/h in a large-scale (300 MW) coal-fired power plant, there was a drastic reduction of NO x emissions, about 10% ( Wang et al., 2011 ).
Coal combustion by-products production in USA and EU is estimated in around 115 million tons per year. A large portion of this production is accounted for the coal fly ash (CFA). Cement and concrete manufacturing consumes most of the CFA produced. Zeolite synthesized from CFA is a minor but interesting product, with high environmental …
