FGR系统中文丘里管的研究现状及展望

The research status and prospect of venturi tude in FGR system

为达到节能减排的要求,我国严格控制NO_(x)的排放标准(≤30 mg)。FGR (烟气再循环)系统中文丘里管的各种参数直接影响其工作性能,从而影响NO_(x)生成量。对FGR系统中文丘里管和表述文丘里管工作性能的评价指标进行简要介绍,归纳总结文丘里管的研究现状,旨在为FGR系统中文丘里管工作性能的进一步优化提供参考。

In order to meet the requirements of energy conservation and emission reduction,the provinces in China strictly control the NO_(x) emission standard(≤30 mg).The various parameters of the FGR system venturi tube can directly affect its performance and thus affect the NO_(x) emissions.This paper briefly introduces the working principle of the FGR system and the performance indicators of the venturi tube.Based on the research of many scholars at home and abroad,the research status of the venturi tube is summarized.The work in this paper can provide some reference for the further optimization of the performance of venturi tube in FGR system.
