摘　　要：为解决秸秆类生物质颗粒燃料的结渣问题,通过在玉米秸秆中分别添加4种添加剂,对其结渣率、灰熔融特性、燃料特性等开展试验研究,并进行验证试验。结果表明,添加质量分数3%的MgCO3、CaCO3、Al2O3添加剂均可有效改善结渣效果,其中MgCO3的抗结渣效果最好,结渣率近似为零;CaCO3添加剂结渣率低于10%,抗结渣效果性价比最高。同时,添加添加剂对燃料的燃烧性能无明显影响。这为解决玉米秸秆等生物质固体成型燃料的结渣问题提供了技术依据。In order to solve the slagging problems of the stalks-based biomass pellet fuel,through adding four kinds of additives into corn stalks,the experimental research of the slagging percentage,ash melting and fuel characteristics,together with the validation tests were conducted in this paper. The results showed that 3% of MgCO3,CaCO3 and Al2O3 could change slagging effectively,among which MgCO3 had the best effects,the slagging rate was approximately zero;CaCO3 could result in the highest efficiency in anti-slagging. The slagging rate was less than 10%. Adding additives had no apparent influence on the fuel combustion characteristics. The results can provide a basis for solving the slagging problems of the corn stalks-based solid fuel.
