| 摘 要： | 文中介绍了一种实现锅炉尾烟含氧量软测量的方法。烟气含氧量主要受煤质变化、锅炉漏风、未完全燃烧等因素的影响。考虑到风量和给煤量的测量精度问题，文中采用燃烧机理分析以及统计分析方法，首先建立风量和给煤量的软测量模型。采用多传感器数据融合方法，并加以煤质校正等处理，得到一个完整的氧量软测量模型。通过仿真验证，建立的氧量软测量模型能较好的反映烟气含氧量的变化。

| Abstract: | A new method realizing the soft-sensing of oxygen content in boiler flue gases is presented. Oxygen content is primarily affected by the change of the property of coal, boiler air leakage, incomplete combustion process and etc. Because the measurement precision of air flow and fuel flow commonly is poor, soft-sensing models of air flow and fuel flow are set up through the mechanism analysis and the statistical analysis. An integrated soft-sensing model of oxygen content is constructed then based on multisensor data fusion, attaching the correction of the property of coal. Simulation results show that the output of soft-sensing model fits well with the practical oxygen content. |
