Alkali metal transformation and ash deposition performance of high alkali content Zhundong coal and its gasification fly ash under circulating fluidized bed combustion

•Zhundong (ZD) coal and its gasification fly ash are high alkali fuels.•The transformation of Na and K during high alkali fuels combustion was studied.•The release of Na during fly ash combustion was less pronounced than it was in the ZD coal.•Variation in the bed temperature did not greatly affect...
