摘要/Abstract

摘要： 近年来，国家及各地政府相继出台政策要求燃气锅炉必须实现超低氮排放。目前，大功率等级的燃气锅炉改造普遍采用低氮燃气燃烧器+烟气再循环系统技术路线，改造后普遍出现锅炉振动问题。依托2种大功率等级的燃气锅炉低氮改造项目，研究了低氮燃气燃烧器燃料配比、助燃空气氧含量、燃烧火焰长度三大因素对锅炉振动的影响，提出适用于该类型锅炉燃烧系统的技术改造原则和具体设计要求，为后续改造提供技术支撑。

关键词: 超低氮, 大功率, 燃烧器, 锅炉振动, 燃料配比, 氧含量, 火焰长度

Abstract: In recent years, the state and local administration of China have issued related policies successively in which it is required for gas boilers to achieve ultra-low nitrogen emissions. At present, the technical route of low-nitrogen gas burner coupled with flue gas recirculation system is chosen by most of the retrofits of high-power gas-fired boilers. However, boiler vibration generally occurs after the retrofit. On the basis of two types of high-power gas-fired boiler low-nitrogen retrofit projects, the effects of three major factors, i.e., the fuel ratio of the low-nitrogen gas burner, the oxygen content of the combustion air, and the combustion flame length on the vibration of the boiler were studied respectively. And then, the technical retrofit principles and specific design requirements applicable for this type of boiler combustion system are proposed, which will provide strong technical support for the follow-up retrofit tasks.

Key words: ultra-low nitrogen, high power, burner, boiler vibration, fuel ratio, oxygen content, flame length
