| 摘 要： | 选用经酸洗法脱灰的煤和秸秆制得实验样品。实验采用热重差热分析仪和气相色谱质谱联用仪对不同比例混合的煤和秸秆以及附加不同比例KOH的样品进行燃烧实验，研究秸秆与煤以不同比例混燃过程中碱金属K对NO释放特性的影响。研究结果表明，脱灰样品中参混一定比例秸秆能有效抑制NO释放，且在燃烧过程中NO释放曲线为单峰曲线。低秸秆比例的脱灰混样中，随着K含量的递增，对NO还原的催化作用越强，但含量达到一定值时趋于稳定。混燃气氛中氧气含量越低对还原NO越有利。

| Abstract: | The effects of alkali metal K on the release characteristics of NO during the co-combustion of a Tiefa coal deashed by acid washing and mixed with corn straw or different proportions of KOH were investigated using an online themogravimetric-gas chromatographic system. The results indicate that it is effective to inhibit the release of NO to add a certain proportion of straw in the deashed samples. As the proportion of straw increases, the peak number of release rate of NO gradually changes from one peak to ... |
