摘要: 温度是有机废液焚烧的重要参数,也是影响焚烧炉结焦结渣的重要因素.实验研究分析了采用流化床焚烧处理有机浓缩废液时,焚烧温度对结焦结渣的影响.研究表明:随着焚烧温度的升高,焚烧炉的结焦结渣程度逐渐加大,渣样晶相由以Na2SO4、NaCl等为主转变为以Na2SO4、Na2Si3O7等为主,且Na2Si3O7在渣样中的比重随着焚烧温度的升高而升高;向焚烧炉添加石灰石、Fe2O3粉末、高岭黏土等添加剂能够较好地抑制焚烧炉的结焦结渣.

Abstract: Incineration temperature is an important parameter to evaluate organic wastewater combustion and is also a significant factor affecting the formation of agglomeration. In the process of fluidized bed incineration of organic-condensed wastewater, the influence of incineration temperature on agglomeration was investigated experimentally and discussed. The results of the combustion tests showed that the intensity of agglomeration and the ratio of Na2Si3O7 in the clinker sample were growing with increasing incineration temperature. Moreover, the dominant crystals of Na2SO4,NaCl were converted into the crystals of Na2SO4,Na2Si3O7 etc. Using additives such as limestone,ferric oxide powder,kaolinite might be effective to reduce the agglomeration problem as illustrated in this paper.
