Analysis and Calculation of Flue Gas SO_2 Concentration Based on Ultimate Analysis Contents of Coals

XING De-shan,YAN Wei-ping(North China Electric Power University,Baoding 071003,China)  
A number of formulae have been deduced for calculating the SO_2 concentrations of dry flue gas,wet flue gas and saturated flue gas based on the ultimate analysis contents of coals.The affection of S_(ar),excess air coefficient and other ingredients in coal on SO_2 concentration are discussed.A SO_2 concentration conversion formula among different excess air coefficient was obtained.Two criterion are also given which can directly compare SO_2 concentration of different coals.Finally,other two formulae are given which can calculate SO_2 concentration simply by the converted sulfur content or S_(ar)/C_(ar).All of the formulae can meet the need of SO_2 concentration calculation under various conditions very well,and the calculation data can be taken as the foundation compared with those measured.
