文摘

Spread of 1.5‰ was observed in δ202Hg values of raw coals and coal related samples. The δ202Hg values were more negative in fly ash than those in the raw coal. The flue gas had a significant Hg fractionation after desulfurization. The stack emissions were enriched with lighter isotopes compared with the raw coal.
