动力煤燃烧对NO_x还原反应的影响

Impact of steam coal combustion on NO_x reduction reaction

NOx的生成和分解过程十分复杂,目前许多有关NOx生成和分解的模型仍停留在理论定性阶段,而且涉及NO和N2O还原反应的一些均相的化学动力学参数还没有获得,因此要建立合适的NOx生成和分解模型困难较大。在国内外研究的基础上,建立一个以研究NO和N2O化学反应动力学为基础的循环流化床锅炉,开展在典型动力煤燃烧表面分解NOx化学动力学方面的研究,最终得到其动力学参数。

The process of NOx formation and decomposition is very complicated,while many NOx generation and decomposition models stays in theoretical qualitative stage,and many homogeneous chemical kinetic parameters involving NO and N 2 O reduction reactions have not been obtained therefore,it is difficult to build the appropriate generate and decompose models.The authors established a circulating fluidized bed boiler basing upon studies of NO and N 2 O chemical reaction kinetics,and conducts chemical kinetics of NOx decomposition on surface of steam coal combustion on the basis of domestic and foreign research.
