摘要

三次空气分级天然气燃烧器中稳焰器可以大幅度降低不完全燃烧热损失

但却提高了NOx的排放浓度

其最佳工况点为天然气管与一次风管、二次风管和三次风管的流通面积之比为1∶5.51∶1.92∶3.97及天然气管与一次风管、二次风管的插深之比为1∶0.75∶0.208 3。试验表明

稳焰器的安装位置影响NOx的排放量

烟气中NOx最低排放量为24.26 mg/m3。

Abstract

The flame-stabilizer in three air-sorting natural gas burner can significantly reduce the incomplete combustion loss

saving energy

however

the concentrition of NOx emission being risen.The optimal condition of the said burner is as follows:the flow passage area ratio of natural gas pipeline

the primary air duct

the secondary air duct

and the tertiary air duct is 1∶5.51∶1、1.92∶3.97

an inserted depth ratio of the natural gas pipeline

the primary air pipe

and the secondary air pipe is 1∶0.75∶0.208 3 respectively.Test shows that the installed location of flame-stabilizer affects the concentration of NOx emission

the lowest concentration of NOx emission in flue gas is 24.26 mg/m3.
