Technical Problem
[0002]在工业燃烧过程中，氮氧化物主要污染物之一，其生成与燃烧温度和氧浓度密切相关，随着环保要求的不断提高，低氮燃烧技术已成为工业锅炉和炉窑等领域的重要研究方向，传统的燃烧技术在燃烧过程中容易产生大量的氮氧化物，这些有害气体不仅会导致空气污染，还会对人体健康和环境产生不良影响，现有的低氮烧嘴技术中，大多数采用了预混合燃烧或分级燃烧的方式，然而，低氮烧嘴内大部分不具备有回流机制，难以对未能充分燃烧的烟气进行回流燃烧处理，从而导致系统能效较低，且降低了其燃烧效率
Benefits of technology
[0011]（1）本实用新型通过设置检测器、回流管和回流结构，当喷嘴管道通过检测器对内部的烟气进行检测处理，当检测到燃烧不充足的烟气时，通过电机带动第二阀碟进行转动，由于第二阀碟通过防滑带与第一阀碟相连接，第一阀碟和第二阀碟会同步转动，而后喷嘴管道内的烟气会通过回流管重新进入到燃烧区域，该低氮烧嘴通过回流结构、检测器和回流管之间的配合，将燃烧产生的部分烟气强制吸入内置燃烧室与燃料和空气充分混合，形成低温、低氧的燃烧环境，从而减少氮氧化物的生成，强制烟气回流能够改善燃料与空气的混合效果，使燃烧更加充分，减少未完全燃烧热损失，提高整体燃烧效率。

Abstract
The utility model discloses a kind of forced flue gas backflow low-nitrogen burner, belong to industrial burner technical field, it includes nozzle body, the side of the nozzle body is equipped with nozzle pipeline, the nozzle pipeline outer lap joint has protective structure, detector is fixedly connected in the nozzle pipeline, the nozzle pipeline outer connection has backflow pipe, backflow structure is equipped outside the backflow pipe, the backflow structure is rotatably connected in nozzle pipeline.In the utility model, by setting detector, backflow pipe and backflow structure, the low-nitrogen burner is cooperated between backflow structure, detector and backflow pipe, part of flue gas generated by combustion is forcedly inhaled into built-in combustion chamber and fuel and air is fully mixed, low-temperature, low-oxygen combustion environment is formed, so as to reduce the generation of nitrogen oxides, forced flue gas backflow can improve the mixing effect of fuel and air, make combustion more fully, reduce incomplete combustion heat loss, improve overall combustion efficiency.
