基于能量损失的汽轮机循环水泵优化运行研究
循环水泵优化运行的目的是通过调整循环水泵的运行台数使汽轮发电机组单位上网电量所消耗的能量最少.现有文献在确定机组微增出力和凝汽器真空时都需要用到理论计算或变工况曲线拟合,难免计算结果与实际情况相偏离.针对上述问题,提出了一种以冷端能量损失为研究对象的循环水泵优化运行方法,该方法以热损率作为循环水泵切换运行的判定准则,进而计算出各运行工况切换点循环水温升的比值,以温升的比值来衡量循环水泵运行的合理性,极大地提高了试验测试的精度和方便性,并将该方法应用到某300MW机组中....

Damage and deterioration mechanism and curing technique of concrete structure in main coal cleaning
Concrete structures in main coal cleaning plants have been rebuilt and reinforced in the coal mines of the Shanghai Da-tun Energy Sources Co. Ltd., the first colliery of the Pingdingshan Coal Co. Ltd. and the Sanhejian mine of the Xuzhou Mining Group Co. Ltd. In these projects, the operating environment and reliability of concrete structures in the main plants of the three companies were investigated and the safety of the structures inspected. Qualitative and quantitative analyses were made on the spe-cial natural, technological and mechanical environments around the structures. On the basis of these analyses, we discuss the long-term, combined actions of the harsh natural (corrosive gases, liquids and solids) and mechanical environments on concrete structures and further investigated the damage and deteriorating mechanisms and curing techniques of concrete structures in the main coal cleaning plants. Our study can provide a theoretical basis for ensuring the reliability of concrete structures in main coal cleaning plants....

Economic Analysis on Rent of Equipment Lease of Coal Enterprise
Rent is the key factor in equipment lease. The business that equipment lease company of coal mining often engaged in can be divided into three kinds, that is sublease, operating lease and inter lease, in term of the difference of the role of lease, character of business, object of the trade and condition of t he market. The problem in rent calculating of the three kind s of lease that equipment lease company of coal mining often involved was an alyzed. Hope to b e helpful to the decision-making of the equipment lease company of coal mining....

多产低碳烯烃工艺参数的变化对产品选择性的影响
针对中国石化荆门分公司现有两套催化裂化装置(一催和二催)的目的产品不同(一催多产低碳烯烃,二催保持较高的液体收率和汽油产率),希望通过调整工艺参数满足要求。通过实验考察了反应时间、剂油比和再生温度对产物分布和选择性的影响。结果表明:延长反应时间,热裂化反应深度会显著增加,干气选择性和氢气产率明显增加,热裂化指数明显上升;增加剂油比是保持丙烯收率、增加总液体收率的优选方案;较高的初始油剂接触温度有利于低碳烯烃的生成,但如果以汽油、柴油为目的产物,则应该适当降低再生温度和油剂的初始接触温度,而不是降低反应温度。...
