前言用改进燃烧方法来抑制NO_x 生成的特殊燃烧技术中有烟气再循环法、二次燃烧法。在应用这些方法之前的基本课题是必须使由燃烧室和燃烧器组成的燃烧炉本身成为低NO_x 燃烧炉。由于作为燃烧炉的关键的燃烧器的形式和结构对生成NO_x 具有最大的影响,如果能够不采用特别的方法来抑制NO_x 的生成,那末可以说是更为理想的。 Preface The use of improved combustion methods to inhibit the generation of NO x special combustion technology flue gas recirculation, secondary combustion method. The basic task before applying these methods is to make the combustion furnace, which consists of the combustion chamber and the burner itself, a low NO x combustion furnace. Since the form and structure of the burner as the key to the combustion furnace have the greatest effect on NO x generation, it can be said to be more desirable if no particular method can be used to suppress NO x formation.
