本文对桥头铝电公司发电分公司二厂#5炉制粉单耗偏高的原因进行了分析,找到了降低锅炉制粉单耗的对策:在建立制粉系统最佳运行操作卡片的基础上,严格按照最佳运行操作卡片进行参数的调整、控制,改变运行人员原来不合理的习惯运行方式,加强管理,充分调动运行人员的积极性,同时不断进行设备改造,就能达到大大降低制粉单耗的目的。运行调整后,磨煤机运行电流降低2-3A,排粉机运行电流降低约5-7A,制粉单耗降低约0.
Evapotranspiration ratio of six major forest types in the Pearl River Delta was studied in this paper, and the six forest types included eucalyptus forest, fruit forest, coniferous forest, shrub fores
This paper presents an improved Dark Dense Vegetation (DDV) method for retrieving 500 m-resolution aerosol optical depth (AOT) based on MOD04-C005 arithmetic with the Moderate Resolution Imaging Spect
土钉支护因其施工简单、造价低、工期短和施工技术成熟等优点,在工程中得到广泛应用,但目前其设计计算理论缺乏,且现行规范给出的变形允许值存在不足:1)土钉墙安全系数计算一般采用传统极限平衡法计算,该方法对于复杂土层的计算精度较差,且不能给出土钉支护结构的变形与稳定性之间的关系;2)现行土钉规范(规程)仅是简单地规定一个变形允许值,没有结合基坑的特点、支护类型、周边环境等因素来规定,更没有将基坑的变形与
