摘要
对水洗预处理后的甜高粱茎秆酵渣进行工业分析、元素分析,热值、燃烧特性、灰分组分和灰熔融特性测试,研究常温下水洗固液比对甜高粱茎秆酵渣燃烧性能的影响。试验结果表明:水洗有助于脱除灰分,增大低位热值,大幅减小原料中的Cl、N元素的含量,降低燃料结渣指数。在常温情况下,采用固液比1∶30进行水洗预处理,确保燃料的各项性能得到提升,减少NO_x和二恶英(PCDD/F)的污染排放。另外,建议进行酸洗以减轻燃料中的碱性化合物含量,进一步减轻结渣趋势。
By analyzing the industrial analysis, element analysis, heating value, combustion characteristics, ash composition and ash fusibility before and after water-washing pretreatment with different solid-liquid ratio, the fuel performance of fermented residue of sweet sorghum stalks was studied at room temperature. It was showed that water- washing can efficiently removed the ash content, enhanced the low calorific value, and greatly reduced the C1, N elements in the fuel, and the fuel slagging index in the ash. At the room temperature, in order to remove the ash, Cl and N elements, and enhance the fuel combustion characteristics, it was suggested that the solid-liquid ratio is at 1：30. At the same time, pickling method should be adopted to reduce the alkaline oxide content in the ash in the next research.
