摘　　要：基于网格化快速采样自动切换(GASS)烟气测试系统对SCR喷氨优化调整试验测试时间、测量不确定度和准确度进行研究,并利用某1000 MW机组进行实例验证。结果表明:GASS烟气测试系统单工况测试时间为传统方法的1/5~1/10,提高了测试效率,可减少试验负荷申请时间。GASS烟气测试系统降低了NO x质量浓度测量不确定度,直接提高了测试准确度和SCR喷氨优化调整效果。Based on the grid automatic sampling switch(GASS)flue gas test system,the test time,measurement uncertainty and accuracy of selective catalytic reduction(SCR)ammonia injection optimization adjustment was studied and the verification test was carried out on a 1000 MW unit.The results indicated that the GASS flue gas test system’s single-mode test time is 1/5~1/10 of the traditional method,which improved the test efficiency and reduced the test load application time.In addition,the GASS flue gas test system reduced the uncertainty of NO x concentration measurement,directly improved test accuracy and SCR ammonia injection optimization adjustment effect.
