摘要/Abstract

摘要： 目前电厂多用石灰石等钙基吸收剂作为脱氯剂，但这些常用钙基吸收剂的脱氯性能并不理想，且会消耗较多的钙资源。本文以玉米秆、棉秆和稻秆为研究对象，实验气氛为空气，在管式炉中模拟燃烧条件，通过实验探究了赤泥、白泥和电石渣对玉米秆、棉秆和稻秆3种不同生物质燃烧脱氯的影响，得出3种添加剂在400~900℃条件下对生物质燃烧脱氯效率的影响，实验结果显示为在400~800℃的条件下脱氯效率随着温度的升高逐渐升高，其中白泥在800℃时对稻秆的脱氯效率达到42.5%，对棉秆的脱氯效率达到37.6%，赤泥对玉米秆的脱氯效率达到30.8%。但是超过800℃以后随着温度的继续升高，脱氯效率反而降低。另外，不同钙基废弃物对不同生物质的脱氯效果不同，在对不同的生物质能源进行燃烧利用时，应选择相应合适的添加剂。

Abstract: Calcium-based sorbents are extensively used as an antichlor in most coal-fired power plants,which consume a large amount of calcium but have a poor dechlorination performance. In this study,the dechlorination performance of red mud,white mud,and acetylene sludge was explored on corn stalk,cotton stalk and rice straw. Air was used as experimental atmosphere,and combustion condition was simulated in a tube furnance. The experiment was carried out at temperatures of 400~900℃. The results showed that the dechlorination efficiency of white mud was 42.5% for rice straw,37.6% for cotton stalk. The dechlorination efficiency of red mud was 30.8% for corn stalk. But when the temperature was above 800℃,the dechlorination efficiency was getting lower with the temperature increase. Besides,different calcium-based wastes had different effects on different biomass materials. So suitable additives should be selected for combustions with different biomasses.
