— Lin et al [13] proposed the thermally co treatment of municipal solid waste incineration fly ash and sewage sludge The rich SiO 2 and Al 2 O 3 in sludge were prone to react with the compounds in fly ash to form low melting temperature eutectics and greatly reduce the ash fusion temperatures
— In addition the heavy metals in fly ash were also checked The results indicated that double washing and triple washing could remove % and % of chlorine from fly ash respectively The double water washing microwave/organic acid could remove about % of chlorine and % and % of insoluble chloride
