摘　　要：选取35台装机容量30万千瓦以上大型火电机组,进行了为期2年的监测。总结出大型火电机组二氧化硫排放规律,对大型火电机组燃煤含硫量、脱硫设施脱硫效率和二氧化硫排放浓度三者间的关系进行了统计分析,建立了线性回归方程,进而对燃用不同含硫量燃煤的火电机组执行不同排放标准时,配套脱硫设施需要达到的脱硫效率进行了预测。35 large thermal power units with a load capacity over 300000 kilowatts were selected and have been monitored for two years.The laws of sulfur dioxide emission from large thermal power units were summarized.Stepwise multiple linear regression analysis was performed to study the relationship among the coal sulfur content,efficiency of flue gas desulphurization and concentration of sulfur dioxide emission and a regression equation was established.The desulphurization efficiency of desulphurization equipment should reached was predicted when burning the coal with different sulfur content and carrying out different standard of sulfur dioxide emission.
