| 摘 要： | 针对直接空冷凝汽器运行中存在的问题。通过对空冷凝汽器变工况计算，找出了环境温度、迎面风速、汽轮机排汽量变化对汽轮机背压、发电标准煤耗率的影响关系。结果表明：空冷凝汽器的运行工况与设计工况差别较大，用户应在变工况下合理确定空冷凝汽器运行方式。

| Abstract: | Aiming at the problem of direct air-cooled condenser in actual operation,through the calculation in variable working condition of air-cooled condenser,finds out the influence relations of the environment temperature,the head-on wind speed and the change of quantity discharged of the steam turbine for the back pressure of the steam turbine and standard coal loss rate of the power generation. The result shows that the difference of operation and design working conditions of air-cooled condenser is very great,user should determine in reason the operation way of air-cooled condenser in variable working condition. |
