Solid waste is mainly from urban garbage and industrial waste. Sludge is from water treatment factories, paper mills, chemical factories, pharmaceutical factories, rivers and lakes. The waste and sludge are very harmful to water organisms, human health and drinking water, and directly affect the environment. Sludge and waste also occupy large areas of land. There are several methods to treat waste and sludge, such as burial, chemical treatment and incineration. Incineration is more effective than the展开更多

The framework can be used to evaluate the energy and exergy losses in each component. Furthermore, the energy and exergy efficiencies have also been computed and compared for the individual components as well as for the overall plant.展开更多
文中对 P91 钢两类焊缝的拉伸、冲击、硬度,特别是断裂韧性进行了试验研究。结果表明:强度、硬度高,冲击韧性低的 R 焊缝具有低的断裂韧度,强度、硬度低,冲击韧性高的 D 焊缝具有高的断裂韧度;R 焊缝的低韧性主要与其晶粒粗大、网状晶...文中对 P91 钢两类焊缝的拉伸、冲击、硬度,特别是断裂韧性进行了试验研究。结果表明:强度、硬度高,冲击韧性低的 R 焊缝具有低的断裂韧度,强度、硬度低,冲击韧性高的 D 焊缝具有高的断裂韧度;R 焊缝的低韧性主要与其晶粒粗大、网状晶界及焊接过程中焊接线能量和电流偏大有关,而 D 焊缝的低强度与高的断裂韧度则与焊后二次回火时温度过高有关。对于 R 焊缝,用厚度 12mm 的三点弯曲(SEB)试样测得的条件 KIC(Kq)与厚度 25mm 的紧凑拉伸(CT)试样测得的有效 KIC基本一致。展开更多
