基于主元分析的scr烟气脱硝系统入口nox生成量预测模型
, PP. 84-89
Keywords: 烟气脱硝系统,scr,nox生成量,预测模型,主元分析,非线性拟合
Abstract:
针对选择性催化还原(scr)烟气脱硝系统喷氨量控制的大迟延特性,使得难以实现其自动控制的问题,将机组主要运行参数与scr烟气脱硝系统入口nox生成量相关联,通过主元分析确定影响nox生成的主导因素。基于主元分析结果,通过非线性拟合方法建立了nox生成量预测模型,并将nox生成量模型预测值与实测值进行对比。结果表明:机组处于稳态过程时,模型预测值与实测值吻合较好;机组处于动态过程时,模型预测值与实测值之间具有一定的偏差,模型预测值变化较实测值提前约100s。因此,该预测模型可作为scr烟气脱硝系统喷氨量控制前馈,从而克服系统的大迟延特性,同时可用于控制二次风挡板。
