摘要

烟气SO2浓度是CFB锅炉重要的环保指标也是计算脱硫效率的主要依据。提出了一种使用公式C0SO2=55 922×St

ar/Qnet

ar计算CFB锅炉烟气SO2浓度的简便计算方法

该方法无需使用元素分析化验结果

仅通过燃料的收到基低位发热量和全硫计算出锅炉烟气SO2浓度和脱硫效率。CFB锅炉脱硫的计算效率与实际效率不同

通常实际脱硫效率要低于计算脱硫效率。

Abstract

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.
