民用燃具低NO_(x)燃烧技术研究进展与展望

Research Progress and Prospect of Low NO_(x) Combustion Technologies for Domestic Gas Appliances

阐述氮氧化物生成机理及民用燃具燃烧技术,综述可用于民用燃具的低NO_(x)燃烧技术(分段燃烧技术、浓淡燃烧技术、全预混燃烧技术、烟气再循环燃烧技术、催化燃烧技术)研究进展,分析优缺点,提出多种低NO_(x)燃烧技术结合可进一步降低NO_(x)排放的思路。

The generation mechanism of nitrogen oxides and combustion technology of domestic gas appliances are expounded.The research progress of low NO_(x) combustion technologies(staged combustion technology,rich-lean combustion technology,fully premixed combustion technology,flue gas recirculation combustion technology and catalytic combustion technology)that can be used in domestic gas appliances are reviewed.The advantages and disadvantages are analyzed,and the idea that the combination of various low NO_(x) combustion technologies can further reduce NO_(x) emissions is put forward.
