我国大多数合成氨企业,至今仍然是个“电老虎”。每吨合成氨成本中竟有1/4是电费。如何使企业的电力设备在最佳状态下运行,以降低电耗,减少电费开支,是降低合成氨成本的一个重要方面。提高功率因数,不但可降低受电设备的电能损耗,而且能从电业部门获取“功率因数奖励”,由此减收电费。例如,象陕西兴 Most of the synthetic ammonia companies in China are still “electric tigers”. One-fourth of the cost of ammonia per ton is electricity. How to make the company’s power equipment operate in the best condition to reduce the power consumption and reduce the electricity expenses is an important aspect of reducing the cost of synthetic ammonia. Increasing the power factor can not only reduce the power loss of the power receiving equipment, but also obtain “power factor incentives” from the electric power sector, thereby reducing the electricity bill. For example, like Shaanxi Xing
