| 摘 要： | 为了研究添加剂对秸秆类颗粒燃料抗结渣的机理，该文以玉米秸秆颗粒燃料为研究对象，通过添加MgCO3、CaCO3、Al2O3 3种添加剂，对其灰渣进行结渣特性、灰渣形貌、化学组成等试验研究。结果表明，添加添加剂后玉米秸秆颗粒燃料灰渣形貌发生明显变化，灰渣尺寸越小，表面越粗糙，孔洞较多；Si、K元素是玉米秸秆颗粒燃料引起结渣的主要元素，Mg、Ca元素与Si、K元素反应生成新的化合物而具有抗结渣效果；Al元素亦与Si、K等元素发生反应生成了新的硅酸盐类。即添加剂与秸秆中的Si、K等碱金属元素发生反应生成了新的化合物抗结渣。研究结果为解决秸秆类固体成型燃料结渣问题提供了理论依据。

| Abstract: | In order to investigate the influence of additives on anti-slagging characteristics of the stalks pellet fuels, three kinds of additives, MgCO3, CaCO3, Al2O3, were added into the pellet fuels to experiment on the slagging characteristics, ash appearance as well as the chemical components of the ash. The results show that adding additives can result in the considerable changes of the ash appearance of the corn stalks pellet fuel, the smaller the size of the ash pellet, the more course and holes its appearance will be. Si, K account for the main elements of slagging during the combustion of corn stalks pellet fuel. The new component of Mg and Ca with Si and K after reaction has anti-slagging effect. The new silicate comes into being after the reaction of Al with Si and K. It is concluded that the new component of additives with Si and K after reaction has anti-slagging effect, and the results can provide a theoretical basis for solving the slagging problems of the stalks solid fuels. |
