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。
The industrial analysis, elemental analysis, calorific value, combustion characteristics, ash fraction and ash fusion characteristics of the pretreated sweet sorghum stalks were studied. The effects of solid-liquid ratio on the combustion performance of sweet sorghum stalks Impact. The test results show that water washing can help to remove ash, increase low calorific value, greatly reduce the content of Cl and N in the raw material, and reduce the fuel slagging index. At room temperature, the solid-to-liquid ratio of 1:30 was used to pretreat water to ensure that the performance of the fuel was improved and the emission of NO x and PCDD / F was reduced. In addition, pickling is recommended to reduce the amount of basic compounds in the fuels and further reduce slagging tendency.
