循环孔高度对炉内温度场、燃烧情况和 NOx生成都有很大影响。保持立火 道其他结构不变,只改变循环孔高度,研究表明:内循环率会随着跨越孔高度的增加而呈现先增加后降低的趋势,循环孔高度适当的增加,可以增强立火道高向温度的均匀性,以及降低NO的排放。
The height of circulating hole has a great influence on the temperature field, combustion and NOx generation in the furnace. The research shows that the internal circulation rate will increase first and then decrease with the increase of the height of the spanning hole. The appropriate increase of the height of the circulating hole can enhance the uniformity of the high temperature of the riser and reduce the emission of No.
