摘要

针对玉米秸秆燃烧结渣率高的问题,将少结渣原料油松与玉米秸秆混合燃烧,采用热重分析结合扫描电子显微镜（SEM）及电镜能谱分析,研究油松的添加对玉米秸秆燃烧特性及结渣特性的影响。结果表明：油松-玉米秸秆混合燃料在燃烧过程中存在一定的交互作用,随温度升高由抑制作用向协同作用转变,再由强协同转为弱协同。当玉米秸秆与油松混合比例为4∶6时,整体燃烧特性最佳,其燃尽温度提高至475.6 ℃,稳燃指数提高至8.9379×10^-6 mg/（K²·min）,综合燃烧特性指数最高提升至0.0929×10^-8 mg²/（K³·min²）,在鼓风强度为0.1 m/s时,其结渣率由56.25%降至9.87%,结渣率下降82.45%,灰渣中Si、Na、K碱金属元素含量由46.42%下降至29.93%。油松的添加可显著增强玉米秸秆的燃烧特性,并有效降低结渣率。

Abstract

In order to address the problem of high slagging rate of corn straw combustion, mixing oil pine with less slagging feature and corn straw to produce the mixture combustion, using thermogravimetric analysis, SEM scanning and energy spectrometry, the effect of oil pine on the combustion characteristics of corn straw and slagging characteristics is studied. The results show that: there is a certain interaction during the combustion process of the oil pine-corn straw mixed fuel. As the temperature rises, it changes from inhibitory effect to synergistic effect, and then from strong synergistic effect to weak synergistic effect. When the mixing ratio of corn straw and oil pine is 4:6, the overall combustion characteristics are the best, the combustion temperature increases to 475.6 ℃, the stable combustion index increases to 8.9379×10^-6 mg/（K²·min） and the combined combustion characteristics index increases to 0.0929×10^-8 mg²/（K³·min²）, and the slagging rate decreases from 56.25% to 9.87% with the blower strength of 0.1 m/s, the slagging rate decreases by 82.45%, and the content of Si and Na, K alkali metal elements in the ash decreases from 46.42% to 29.93%. The addition of oil pine can significantly enhance the combustion characteristics of corn straw and effectively reduce the slagging rate.
