通过对强烈燃烧区合理组织混合方法的研究发现,组织混合不仅取决于气流结构,而且也受燃料引入炉内的方法和位置的制约。并以图示的方法表示出了强烈燃烧区燃烧过程的参数与燃烬燃料的过剩空气系数α~C之间的关系,即局部的NOx、化学不完全燃烧损失q_3、总的机械不完全燃烧损失q_4、着火燃料的机械不完全燃烧损失q_4。、同过剩空气系α~C的关系。同时详细介绍了7种抑制炉内NOx捧放量的实际应用方法。即两级混合燃烧、推迟混合-扩散燃烧法(尖峰给水加热锅炉系统)、推迟混合-动力燃烧法三级混合燃烧、回流方式燃烧、双区锅炉燃烧和循环流化床锅炉燃烧。
Through the study of the rational organization and mixing method in the intense combustion zone, it has been found that the mixing of the tissues not only depends on the structure of the air flow, but also depends on the method and location of introducing the fuel into the furnace. And shows the relationship between the parameters of the combustion process in the intense combustion zone and the excess air coefficient α ~ C of the fuel in the combustion zone, ie, the partial NOx, the incomplete combustion loss q_3, the total mechanical incomplete combustion Loss q_4, incomplete combustion of the fuel burning machinery loss q_4. , With excess air system α ~ C relationship. At the same time, seven kinds of practical methods to suppress the amount of NOx in the furnace are introduced in detail. That is, two-stage mixed combustion, postpone hybrid-diffusion combustion (spike water heating boiler system), postpone hybrid-dynamic combustion three stage mixed combustion, backflow combustion, dual zone boiler combustion and circulating fluidized bed boiler combustion.
