摘要

依据锅炉负荷与氧量的相关性探讨了锅炉运行氧量特性

并以此分析锅炉在低负荷下以SOFA技术运行时NOx排放质量浓度高的原因;同时

从理论上分析了燃料分级燃烧技术与锅炉低负荷工况特性相匹配的原因

在此基础上提出了双分级可调低NOx燃烧技术的设想。认为双分级可调低NOx燃烧技术通过一次风燃烧器沿炉膛高度上的布置方式而实现

通过再燃燃料的调节

可以使炉内燃烧方式在空气分级燃烧与燃料分级燃烧技术之间转换

避免了单一技术的某些固有弊端。该技术可实施性强

风险小

适用于大容量机组锅炉。

Abstract

On the basis of the correlation between boiler load and oxygen content

the operation oxygen content characteristics of the boiler was discussed

and the reason for high NOxemission when the boiler was running at low load with the SOFA technology was investigated.Moreover

why the fuel staging combustion technology is matched with the boiler low load operation condition was theoretically analyzed.On this basis

the dual staging adjustable low NOxcombustion technology was proposed

which can be realized by changing the locations of primary air burner along the furnace height direction.Through regulation of the reburned fuel

the furnace combustion can be switched between the air staging combustion and fuel staging combustion

thus the disadvantages of the pure air staging or fuel staging combustion can be avoided.This technology has well feasibility and low risk

therefore

it is suitable to be used in large scale unit boilers.
