　　The potential of Municipal Solid Waste Incinerator Bottom Ash (IBA) as the sole precursor to synthesize geopolymer was investigated.Ground IBA powder was mixed with water glass and sodium hydroxide solution.After curing, the hardened samples were characterized by FTIR and NMR together with Salicylic acid/methanol extraction (SAM) to identify chemical composition of hardened binder.It was found that the IBA binder consists of one third of alkali-modified C-S-(A)-H and some geopolymeric gel with zeolite-like structures.

磷酸铝污秽对绝缘子泄漏电流的影响
污层受潮是污秽外绝缘放电的先决条件,受潮程度由大气环境与污层吸湿性共同作用.本文采用量子化学与分子动力学模拟方法,分析了不溶物污秽磷酸铝的吸湿特性.在恒湿环境下开展污秽绝缘子放电试验,研究磷酸铝吸湿性对绝缘子泄漏电流的影响.结果表明:污秽中磷酸铝含量达到20％,相对湿度70％及以上时,磷酸铝污秽绝缘子的泄漏电流特征量明显异于常规污秽绝缘子;基波电流电压相位差对污层吸湿性的反映最为灵敏.强吸湿性不溶

灵武电厂#4锅炉壁温测量系统故障率高原因分析
华电宁夏灵武发电有限公司＃4锅炉壁温测量系统平均余额故障次数达到5.2次/月,故障频发,不但增加了维护工作量,更主要的是此现状不利于机组在投入AGC后,负荷大幅度调整过程中运行人员准确监视、判断采取措施防止超温.而针对引起故障的主要原因采取的首要措施就是降低前置器工作的环境温度。对锅炉炉墙进行保温加厚覆盖，减少锅炉对环境的散热，从而降低环境温度。更换前置器的工作位置，通过对现场周围环境测温检查发现
