SO2 concentration in flue gas is an important environmental index for CFB boilers
and is also the main basis for desulfurization efficiency calculation.A simple calculation method for SO2 concentration was proposed
which applying the equation C0SO2=55 922×St
ar/Qnet
ar.This method doesn't need the ultimate analysis results
it can obtain the SO2 concentration and desulphurization only via the low calorific value(received basis)and total sulfur content of the fuel.The desulphurization efficiency of CFB boilers includes the calculated desulphurization efficiency and the actual desulphurization efficiency.Generally
the actual desulphurization efficiency is lower than the calculated one.
