Some quantitative comparisonwas given for two kinds of plants.
The mass concentrations of PM17 and PM10 from CFB are 59.5% and
71.2% higher than those from PC, respectively. But the concentrations
of PM1 from both PC and CFB are nearly close. Compared with
PC plants, CFB fires the coal with ash content of 2.5 times of that of
PC coal, but produces equivalent submicron particles and a little high PM10.
