| 摘 要： | 在一携带流反应器上进行了３种煤粉及１种石油焦再燃烧还原ＮＯ试验，燃料挥发分分布在１０．０２％－３９．８１％之间。研究结果表明：在相同的试验条件下，ＮＯ再燃还原效率随煤级别提高而降低；随空燃比增而降低；反应区温度增加有利于ＮＯ与煤还原反应。

| Abstract: | Three kinds of coals and a petroleumcoke,with volatile matter ranging from 1002% to 3981%,were used to reburn to reduct nitric oxide in an entrained flow raector.Three factors,coal's rank,stoichiometric ratio,reaction temperature were studied.The nitric oxide reduction efficiency decreasing with increasing airfuel stoichiometry of both primary zone or reburning zone.The NO reduction efficiency is higher when reburning temperture is lower.When NO reacted with different kinds of fuels,the reduction property was nearly proportional to coal's volatile matter. |
