浓淡型双调风旋流燃烧器低NOx特性分析

An Analysis of the Low NOx Emission Feature of a Dense dilute Dual channel Swirl Burner

利用冷态等温模化技术对浓淡型双调风旋流燃烧器进行了模拟实验研究。根据实验结果,对双调风旋流燃烧器的结构及特点进行了分析,研究了此种燃烧器的分级送风和浓淡燃烧技术的特点以及稳燃环所起的重要作用。

An experimental study is conducted of a dense dilute dual channel swirl burner with the help of cold state isothermal simulation technology. On the basis of the test results the structure and features of such a burner are analyzed and a study is conducted of the characteristics of a stepped air feed and dense dilute combustion techniques. In addition, the major role played by a combustion stabilization ring has also been investigated. All the above has led to a better understanding of the mechanism of low NOx emission and partial load flame stabilization of the dual channel swirl burner.
