旋流分级燃烧器的混合及NO_x生成特性的实验研究

Experimental Research on Mixing Characteristic of Swirl Staged Burners and NO_x Formation

能否成功地降低炉内NO_X的生成是与挥发性燃升N能否得到氧气(即火焰初始区)的混合直接有关。文章研究了旋流分级燃烧器的混合特性与NO_X生成特性,指出这种新型燃烧器具有多功能的特点,便于电厂改装和新设计时采用。

Successful mitigation of NOx generation in furnaces is directly related to the mixing homogeneity of nitrogen contained in the fuel with oxygen. The paper discusses the mixing and NOX generation characteristics of the swirl staged burner and points; out that the multi-function feature of this new type of burner makes it useful in retrofiting old power plant as well as the design of new ones.
