摘要
针对切圆燃烧锅炉与对冲燃烧锅炉在不同负荷下的炉膛出口NO_x排放浓度的变化规律进行了研究,从NO_x生成与还原的机理出发,结合基于Fluent的数值计算解释了切圆燃烧锅炉低负荷NO_x升高而对冲燃烧锅炉低负荷NO_x不升高的原因。
The effect of variable load on the NOx emission of different types of pulverized coal fired boilers： tangentialfiring boiler and opposed-firing boiler is investigated. With NOx mechanism of generation and reduction, with the CFD simulations, the reason behind higher NOx emission under lower load for tangential-firing boiler while lower NOx emission under lower load for opposed-firing boiler is analyzed.
