中文摘要	对垃圾焚烧飞灰加压成型后的高温烧结产物特性(抗压强度、烧失率和体积变化率)进行了研究,以期确定焚烧飞灰烧结的最佳操作条件。实验所设定的影响参数包括成型压力、烧结温度、烧结时间、黏土添加剂、水洗预处理。结果表明:成型压力、烧结温度及烧结时间、黏土添加剂、水洗预处理对焚烧飞灰烧结试体的抗压强度增加有积极影响。本实验采用的焚烧飞灰烧结温度范围较窄,1100℃为比较合适的烧结温度,黏土添加剂能有效的降低烧结试体的成型压力而不影响抗压强度。烧结温度、烧结时间增加会使烧结试体烧失率增加,成型压力增加、黏土添加剂、水洗预处理会使烧结试体烧失率下降,综合考虑烧结试体抗压强度、烧失率和样品制备能耗,焚烧飞灰优化操作条件为成型压力3kN,烧结温度1100℃,烧结时间4h,黏土添加含量30%,水洗预处理。; The sintering treatment of fly ash was performed on cylindrical compact specimens at different experimental conditions,including compact pressure,sintering temperature,sintered time,clay additive,washing pre-treatment.The result show compact pressure,sintering temperature,sintered time,clay additive,washing pre-treatment have positive effect on the increase of compressive strength of the sintered products.The compressive strength of sintered products at many experimental conditions was low,clay additive can effectively increase the compressive strength of the sintered products and decrease compact pressure.The ignition loss of the sintered products is increased with the increase in sintering temperature and sintered time,while it is decreased with the increase in compact pressure,clay additive and washing pre-treatment.The optimum sintering condition is:the compact pressure 3 kN,sintering temperature 1 100 ℃,sintered time 4 h,clay additive 30% and washing pre-treatment by taking account of compressive strength,ignition loss and energy consumption of sample making in high pressure comprehensively.; 国家科技支撑计划项目(2006BAC02A18); 国家高技术研究发展计划“863”项目(2002AA644010)
