库车坳陷煤生物标志物组成随成熟度的变化特征

对塔里木盆地库车坳陷三叠系和侏罗系的11个岩心与露头煤样的地球化学分析表明，煤的生物标志物组成随演化程度的增加而有规律的变化：成熟早期（镜质组反射率Ro／1．0％）煤的生物标志物组成反映了沉积环境和生源的特征；成熟晚期（1．10％＜Ro＜1．30％）煤的生物标志物特征受成熟度的控制作用十分明显，生物标志物参数随Ro的增大而增加或减小；高－过成熟阶段（Ro＞1．30％)所有煤样的生物标志物组成已基本趋于一致，而且和湖相泥岩的生物标志物特征相似，该阶段的生物标志物参数不能用来进行油源对比。

Large-scale cooling towers as part of an efficient and cleaner energy generating technology

The present paper will outline the main aspects of the design and construction of cooling towers in Germany in the last decade. As part of electricity generating power plants, cooling towers play a significant role for the availability of reliable energy supplies, in a manner compatible with environmental requirements. They definitely belong to the largest and thinnest concrete structures at present. Because of the combined action of wind, thermal and moisture effects, special care has to be taken with regard to fatigue, cracking and corrosion to ensure an adequate level of safety and durability. Such a design strategy has been employed for the world’s tallest cooling tower at the Niederaussem power plant in Germany, with an overall height of 200 m and thickness values of 22–24 cm. Special considerations included the realistic non-axisymmetric distribution of soil characteristics, wind action due to interference effects (as determined by wind-tunnel tests), optimisation of the shell shape to improve structural and dynamic behaviour, injection of the cleaned flue-gas into the cooling tower, and the use of high-performance concrete (85 MPa) to improve shell resistance against acid attack by the cleaned flue-gas. The paper will present some results of an actual research project on this problem, which was conducted at the University of Wuppertal, to explore the use of high-performance concrete on design, stability and durability of cooling tower shells.

Relationship Between Coal Powder and Its Combustibility

Coal‘s volatile component ,ash and fixed carbon content have different function in different stages of a combustion process,but the traditional coal classification can precisely show its combustion property.In this experiment coal‘s evaluation indeves(ignition index Di),(burn off index Df) were used to qualitatively show the ignition property and combustion ending property of coal samples.Meanwhile,considering actual heating circumstances in calciner(in cement plants),this thesis established the relationship among the ignition index,burn off index and coal‘s industrial analysis value,which makes it possible for the user to predict the quality of coal before using it and is very valuable in practice.
