摘要
为了获得高效清洁的燃烧方式,使用CHEMKIN软件对含氮废气分段焚烧炉的运行参数进行了详细研究.结果表明:过量空气系数存在一个最优区间,较低的过量空气系数不能使还原段升高到足够高的温度,过高的过量空气系数使还原段的还原效果减弱,都会导致较高的污染物排放;延长还原段停留时间有利于降低污染物排放;再燃效果受过量空气系数和炉内温度的制约.
Abstract
In order to obtain efficient and clean combustion mode,a detailed study was conducted on the operating parameters of a segmented incinerator for nitrogen-containing waste gas using CHEMKIN software.The results show that there is an optimal range of excess air coefficient.A lower excess air coefficient cannot raise the reduction section to a sufficiently high temperature,and an excessively high excess air coefficient can weaken the reduction effect of the reduction section,leading to higher pollutant emissions.Extending the residence time of the reduction section is beneficial for reducing pollutant emissions;The effect of reburning is constrained by the excess air coefficient and the temperature inside the furnace.
