中国风电产业的规模和效率探析——以内蒙古自治区为例

对中国数百家风力发电场2008~2010年的发电装机容量和发电效率进行了分析,发现中国的风电场的规模和效率都在递增,但风电场的规模和效率之间的相关性逐年递减,甚至出现了负的相关性。进一步分析了风电第一大省内蒙古的情况,显示装机容量的规模存在着反常的现象,而且装机容量和发电效率之间的相关系数也不稳定。据此分析,对现行的风电发展政策提出了疑问,并给出了相应的政策建议。

膜式机械通风横流冷却塔节能研讨

横流塔由于气水对数平均焓差较小。故在同参数下冷却数较逆流塔大,通常设计中电耗约高46％左右。本文从分析气流在填料中流态出发,探讨填料的相对凸起、风速与传质强度、能耗及投资间关系。由于在一定冷却数下,填料体积与传质强度成反比,前者与塔投资有关,后者当填料间距远小于其长度及高度时,可近似认为仅与填料形状及风速有关,即与能耗有关,故按投资回收期来选择填料形式并决定经济风速才是合理有效的节能方法。样塔提供较原塔节能65.7％的实例。本文亦可供膜式逆流塔参考。

Wind and orientation of migrating birds: A review

Summary Migratory flights are strongly affected by wind, and birds have developed many adaptations to cope with wind effects. By day, overland migrants at high altitudes may often allow crosswinds to drift their tracks laterally from the preferred heading. In contrast, many birds at low altitude adjust their headings to compensate for drift, and may overcompensate to allow for previous drift. The relative motion of landscape features is probably used to sense drift, at least by day. By night, some overland migrants compensate fully for drift but others do not; no pattern is obvious. Over the sea, compensation is rarely if ever total; wave patterns may allow partial compensation. Other adaptations can include reduction of drift by flying at times and/or altitudes without strong crosswinds. Some birds recognize the need to change course to allow for previous wind displacement, and reorient at least roughly toward the original route or destination. Some juveniles en route to previously-unvisited wintering grounds seem to have this ability, but corroboration is needed. Such reorientation may not require a true navigation ability. However, some birds have unexplained abilities to sense the wind while aloft.     

Hot Corrosion of Plasma Sprayed Coatings for Waste Gas Turbine Blades

High temperature corrosion tests in 75%Na2SO4-25%. NaCl molten salt have been conducted on waspalloy specimens plasma sprayed with Co-Cr-B-Si, Ni-Cr-B-Si-hCr3C2, X-40, X-40 + TiC and Ni/Al + Al2O3 coatings, test coupons were exposed isothermally at 750℃up to 200 h. After the corrosion tests, each sample was examined by OM, SEM and EMPA. It was found that X-40, X-40 + TiC and Ni/Al + Al2O3 were violently corroded by the molten salt due to cracking and spalling of the coatings, whereas the Co-Cr-B-Si and Ni-Cr-B-Si + Cr3C2 exhibited superior corrosion resistance, which were thought to be related to the formation of chromium and silicon oxide film. A possible corrosion mechanism had been proposed and it is suggested that the excellent corrosion resistance and high hot-hardness of the two B-Si containing coatings may be of significance for applications in petroleum refining industry as protective coatings of power generating turbine blades which are used under severe corrosion/erosion conditions.
