Application of coal ash to environmental improvement: Transformation into zeolite, potassium fertilizer, and FGD absorbent

The rapid increase in population and economic growth have led to an increase in energy demand. Coal reserves are distributed worldwide, and coal is now known to be the most stable and available energy source. However, utilization of coal as an energy source involves the generation of a great amount of coal ash, and the recycling rate of the ash is rather low. Coal ash is mainly used in civil construction materials, and there is a limit to the demand for coal ash by construction industries: therefore, the increasing amount of coal ash will be a serious problem in the near future. Different applications should be considered. In this paper, three environmentally-friendly methods for coal ash recycling are described. Firstly, alkali treatment can transform coal ash to zeolite, which is used in deodorant and for wastewater treatment and soil improvement. Secondly, potassium silicate fertilizer is produced from coal ash and has a higher retentivity in the soil than that of conventional fertilizers. Thirdly, emission of sulfur dioxide is controlled by flue gas desulfurization using coal ash. It is considered that environmentally-friendly use of coal ash is important from the viewpoints of energy, economy, and environmental strategy in order to realize the concept of sustainable development.

Like father,like son? Intergenerational transmission of values,attitudes, and behaviours in the environmental domain

How is young people's pro-environmental orientation related to their parents' pro-environmental values, attitudes, and behaviours? To answer this question, we examine parent–child similarities of general values as well as specific attitudes and behaviours related to three common household practices: purchasing environmentally friendly products, curtailing electricity use, and handling waste responsibly in a sample of 601 Danish families. Significant and positive, but weak correlations between parents' and children's values are found across all of Schwartz's ten value domains. The parent–child correlations are stronger for specific pro-environmental attitudes and behaviours. The positive correlations suggest that family socialization exert a significant influence on young consumers' pro-environmental orientation. Still, the young generation is, on average, significantly less environmentally concerned than their parents' generation. Implications of these findings are discussed.

论低压系统检修安全四极开关的设置

在停电检修电器设备时,只断开三根相线（火线）而不断开中性线（零线）,常常因中性线上带有危险故障电压引起事故。因此,四极开关是满足电气检修安全需要的隔离设备,是防止电器部分检修时发生电气事故的有效措施,它应符合电气隔离规定的爬电距离、空气间隙、绝缘水平等要求。     

设备动态风险评估与预测研究

工业系统运行中的设备,受系统状态和设备工况的影响,其失效风险具有动态属性。因此,在认识设备失效风险的可能性和严重性的同时,还必须认识和研究设备在系统寿命周期内失效风险的动态属性。设备失效的动态风险因素可以归纳为设备自身失效率变化、设备外部载荷变化、系统结构变化以及功能变化引起的失效后果严重度变化,依此提出了动态风险模型。利用该模型对江苏某储气库水溶造腔系统进行实证研究,获得注水泵失效动态风险图,明确了造腔初期、中后期和注气排卤三个典型阶段的注水泵失效风险波动状况以及波动原因。实证研究说明,运用该分析模型可以推断系统运行周期内设备失效风险的变化状态和趋势,从而适时、有效地控制风险。
